Dome Metal: All Thing You Need to Know

Posted on December 10, 2024 by Love Dome

Dome metal is a key component in many electronic devices. It plays a crucial role in creating responsive switches that we often take for granted. From keyboards to touchscreens, these metal domes are everywhere, providing tactile feedback when pressed.

What Is Dome Metal?

Dome metal refers to a small, circular metal piece that is used in the construction of switches. Typically made from stainless steel, it has a unique design that allows it to flex under pressure. When you press a button on a keyboard or a remote control, it’s likely that a metal dome is at work underneath the surface, responding to your touch.

These metal domes are designed to provide tactile feedback. This means when you press a key or switch, you feel a small “click,” confirming the action has been completed. It’s this feedback that makes dome metal switches so popular in various applications.

Metal Dome Structure

The metal dome structure is relatively simple but highly effective. The metal dome is shaped like a shallow, inverted bowl, allowing it to compress under pressure. When you press on the surface, the dome collapses, causing a contact to form beneath it. This contact triggers the electrical signal, completing the circuit and registering the action. Below is a top view and side view structure of a metal dome.

Characteristics of Dome Metal

Material and production process: metal domes are made of ultra-thin (0.05mm-0.1mm thickness) and ultra-thick (generally high hardness) stainless steel 301 or 304 material.
Thin and small volume: thin product, small volume, easy to install and use.
?High hardness: the general hardness is between HV480-550.
Long life: after special treatment, the life of metal dome can reach more than one million times.
?Surface treatment: the metal dome can be nickel plated, silver plated, gold plated and other different surface treatment to meet different needs ?.
Application: Metal dome is widely used in mobile phones, digital cameras, telephones, mp3 and other digital products. It is mainly used in membrane switch, micro switch, PCB board, and other products.

Metal Dome vs. Metal Dome Array

While individual metal domes are commonly used for single switches, metal dome arrays are essential for applications where multiple presses need to be registered in a small area. Here are some basic differences between the metal dome and metal dome arrays:

1. Metal Dome:

Single Switch: A metal dome is typically used for a single switch or key press. It’s a small, dome-shaped piece of metal that flexes when pressed, triggering an electrical signal.
Compact Design: These are designed for one-to-one interaction, often used in devices with a small number of buttons, such as simple calculators, remote controls, or industrial panels with minimal buttons.
Flexibility: The individual dome is able to compress and return to its original shape with each press, ensuring tactile feedback for the user.
Applications: Commonly used in devices where individual switches are necessary, such as remote controls, calculators, and some industrial applications.

2. Metal Dome Array:

Multiple Switches: A metal dome array is essentially a grid of multiple metal domes arranged in a pattern. These arrays are used in keypads or control panels with a large number of buttons, such as in laptops or multifunctional devices.
Space Efficiency: A metal dome array allows for more switches in a compact space. Instead of having individual domes for each switch, they can be grouped together, saving space and providing a more efficient design.
Durability: Just like single domes, metal dome arrays are built for durability, capable of withstanding millions of presses.
Applications: These are found in devices that require high-density switch layouts, such as keyboards, calculators, complex control panels, and some automotive dashboards.

How Long Do Domes Last?

The lifespan of metal domes can vary based on several factors, including usage frequency, pressure, environmental conditions, and the quality of the dome material. However, here’s some general data on how long metal domes last:

Standard Lifespan: Most high-quality metal domes are designed to last between 5 million to 10 million actuations. This means that with normal use, the metal dome should remain operational and provide the same tactile feedback for millions of presses.
Premium Lifespan: Some premium domes, especially those used in high-end consumer electronics or industrial applications, are designed to last even longer, often reaching up to 20 million actuations.
Environmental Factors: Temperature, humidity, and pressure can affect the lifespan. Metal domes exposed to extreme conditions (e.g., high heat or moisture) may experience wear more quickly. However, in normal indoor conditions, they are quite durable.
Pressure Sensitivity: The amount of pressure applied during each press also affects the longevity. Heavier presses can cause slight deformation over time, while lighter presses tend to preserve the shape and function of the dome for longer.

Overall, high-quality metal domes, if used properly, can provide a reliable and durable solution for long-term applications, with a lifespan that far exceeds many other types of switches.

Dome Metal Applications

Dome metal switches are used in a wide variety of applications. Some of the most common include:

Keyboards
Remote Controls
Calculators
Automotive Dashboards
Consumer Electronics like microwaves, coffee machines, etc
Touch panels
Industrial control panels
Medical devices
Wearable technology
Toys
POS systems
Consumer gadgets

Dome Metal Packaging

When it comes to packaging metal domes for transport and assembly, ensuring their safety and protection is essential. Here are common methods used to package metal domes:

Tray Packaging:

Metal domes are often arranged in custom-designed trays that keep them securely in place during transit. These trays typically feature individual slots or compartments for each dome, preventing any damage.

Tape Rolls:

For bulk orders, metal domes may be attached to adhesive tape rolls. This method allows for easy handling and assembly, as the domes are precisely placed and can be quickly transferred to their intended position.

Vacuum Sealing:

In some cases, metal domes are vacuum-sealed in protective plastic bags to prevent exposure to moisture or dust. This is especially important for high-precision or sensitive components.

Blister Packs:

Metal domes can be packaged in blister packs, similar to the packaging used for small electronics. These packs help protect the domes from physical damage while allowing easy access for assembly.

Plastic Bags:

A simple, cost-effective packaging solution involves placing metal domes into static-free plastic bags. These bags help protect the domes from static electricity, which could damage the components.

Custom Packaging:

For larger quantities or special requirements, manufacturers may use custom-designed packaging solutions. These can include tailored boxes or storage units that optimize space and prevent any movement during transportation.

N/C Switch: What it is & How does it works?

Posted on December 10, 2024 by Love Dome

What is an N/C Switch?

An NC switch is a type of electrical switch that is commonly used in various electronic and electrical circuits. In its default state, the contacts of a normally closed switch remain in the “closed” position, allowing current to flow through the circuit. When the switch is activated, it opens, interrupting the current flow.

N/C Switch: What it is & How does it works?

NC switches are essential in many applications, such as controlling power to specific parts of a system or triggering safety mechanisms. The main idea behind an NC switch is that it is “closed” when not activated and “opens” when it is activated.

What Does NC Mean on a Switch?

The abbreviation NC on a switch stands for Normally Closed. This indicates the switch’s default state when it is not being actively pressed or triggered. In the Normally Closed position, the switch connects two contacts, allowing current to flow freely. When you press or activate the switch, the contacts open, cutting off the flow of current.

Is NC On or Off?

An NC switch is “on” when it is in the normally closed position. In other words, when the switch has not been activated, the circuit is complete, and current flows through the switch. It only turns “off” when the switch is pressed or triggered, causing the contacts to open and interrupt the current.

So, in its natural state, the NC switch is considered “on” because the current is flowing through it. It’s only “off” when the switch opens, preventing the flow of current.

N/C Switch Diagram

Here’s a simple diagram to help you understand how a Normally Closed (NC) switch works:

In this diagram:

The switch is normally in the “closed” position, allowing current to flow through the circuit.
When the switch is activated (pressed or triggered), it opens, stopping the flow of electricity.

This diagram is the basic representation of an NC switch used in various circuits.

What is the Difference Between an NC Switch and a NO Switch?

An NC switch and an NO switch are both fundamental components in electrical circuits, but they function differently.

NC Switch (Normally Closed): As we’ve discussed earlier, the NC switch is closed by default. This means when the switch is not activated, the circuit is complete, allowing current to flow. When the switch is triggered (pressed or otherwise activated), it opens, interrupting the current flow.

NO Switch (Normally Open): The NO switch is the opposite. In its default state, the switch is open, meaning the circuit is incomplete and no current flows. When the switch is activated (pressed or triggered), it closes, completing the circuit and allowing current to pass through. Below is the circuit diagram of these two types:

Key Differences:

Default State:

NC: The switch is closed by default.

NO: The switch is open by default.

Activation:

NC: Pressing or activating the switch opens the circuit, stopping current flow.

NO: Pressing or activating the switch closes the circuit, allowing current to flow.

Application:

NC switches are often used in safety circuits where the system should be active unless manually disabled (e.g., emergency stop buttons).

NO switches are commonly used where the circuit needs to remain off until activated (e.g., light switches).

How Does an NC Button Work?

An NC button operates similarly to an NC switch. When the button is in its default (unpressed) state, the circuit is closed, and current flows. Pressing the button interrupts the flow of current by opening the switch contacts.

For example, if you have a safety system that needs to be deactivated only when a button is pressed, an NC button is ideal. The system would remain active as long as the button remains unpressed (normally closed), and pressing it would disable the system (open the circuit).

How Do I Know When a Switch is Off?

To know when an NC switch is off, look for the following:

Visual Indicators: Some switches have indicators, such as LED lights or labels, to show whether the switch is in the “on” or “off” state.
Physical Position: The position of the switch can also tell you its state. If the switch is pressed or toggled, it will show as “off” (open position). When not pressed, it’s in the closed state (on).
Multimeter Measurement: You can use a multimeter to measure the continuity of the switch. If the switch is open, the meter will show no continuity, indicating the switch is off.

By using these simple methods, you can easily identify when an NC switch is off.

What is an Example of a Normally Closed Switch?

An excellent example of an NC switch is the doorbell switch. The switch is normally closed when the doorbell button is not pressed. This keeps the circuit active, allowing the chime to sound when you press the button.

Another common example is the emergency stop button in machines or industrial equipment. The button stays in a normally closed state, keeping the machine running until the button is pressed to stop it.

What are snap switch definition?

Posted on December 9, 2024 by Love Dome

What is a Snap Switch?

A snap switch is a type of mechanical switch designed for quick and precise operation. It features a spring-loaded mechanism that snaps into place when activated, ensuring a reliable connection or disconnection of an electrical circuit. This mechanism allows the switch to operate with speed and accuracy, making it a dependable choice for various applications. Snap switches are often used in industrial machines, household appliances, and automotive systems, where precision and reliability are crucial.

The design of snap switches focuses on reducing wear and tear. Their spring mechanism minimizes slow movements, which could lead to contact damage over time.

What is Another Name for a Snap Switch?

Snap switches are also commonly referred to as “quick-action switches.” This alternative name highlights their defining characteristic: the ability to switch between positions quickly and effectively. The rapid action of these switches sets them apart from slower manual switches, such as toggle or push-button types.

In technical contexts, they might also be labeled as “mechanical limit switches” when used to detect position or limit movement in industrial settings. The versatility of the snap switch has led to its widespread adoption under various names across different industries.

How Many Types of Snap Switches Are There?

Snap switches come in multiple types, tailored to different electrical and mechanical requirements. Below are the primary types:

1. Single-Pole, Single-Throw (SPST)

This is the simplest form of snap switch. It has one input and one output terminal, functioning as an on-off switch. It’s commonly used for straightforward tasks like controlling lights or small appliances.

2. Single-Pole, Double-Throw (SPDT)

This type has one input terminal and two output terminals. It allows the user to switch between two circuits. SPDT snap switches are popular in multi-functional devices or applications requiring alternate paths for current.

3. Double-Pole, Single-Throw (DPST)

DPST switches have two inputs and two outputs, controlling two circuits simultaneously. They are often used in systems requiring separate but simultaneous switching, such as dual power supplies or large appliances.

4. Double-Pole, Double-Throw (DPDT)

This type is more complex, offering two inputs and four output terminals. DPDT snap switches are used for reversing the direction of motors, switching between different power sources, or managing complex electrical systems.

Snap Switch vs. Toggle Switch

While both snap switches and toggle switches are used to control electrical circuits, their differences lie in their mechanisms and applications.

Mechanism

A snap switch uses a spring-loaded mechanism that quickly moves the contacts into position. This design provides a tactile click and ensures reliability over repeated use. Toggle switches, however, use a lever mechanism. While functional, the movement in toggle switches is slower and more manual compared to the quick action of a snap switch.

Applications

Snap switches are commonly found in safety-critical systems, automated machinery, and devices requiring precise and rapid switching. Toggle switches, on the other hand, are more suitable for manual operations, such as in home light switches or vehicle dashboards.

Precision

Snap switches often outlast toggle switches in demanding environments due to their robust design and reduced wear on contacts.

Advantage of a Snap Action Switch

Quick Response
High speed switching
High repeatability
Compact design
Reduced Contact Wear
Reliability

How to Switch Snap to Dark Mode?

This question applies to software interfaces rather than physical switches. If you’re using a software platform or app associated with the term “snap,” you can typically switch to dark mode by following these steps:

Open the settings or preferences menu of the app.
Look for “Appearance,” “Display,” or “Theme” settings.
Select the “Dark Mode” or “Night Mode” option.

For hardware devices, “dark mode” settings might not apply unless the device has a digital interface. If this is about smart switches with app controls, refer to the app’s documentation for enabling dark mode.

How to make a metal dome?

Posted on December 6, 2024 by seo_li

How to make a metal dome? The first step in making a metal dome is to choose the right material. After determining the material, the next step is to design and plan the metal dome. During the design process, factors such as the shape, size, elastic coefficient, and installation method of the dome need to be considered to ensure that the dome can meet the needs of actual applications. Next, the metal dome can be processed and manufactured. Finally, the metal dome needs to be quality tested to ensure that the quality and performance of the metal dome meet the design requirements and usage standards.

What is metal dome?

A metal dome is a thin sheet-like component made of a metal material (such as stainless steel 301 or 304). It usually has a specific shape and size, can be deformed when subjected to external force, and quickly returns to its original shape after the external force is removed.

Metal domes are mainly used in membrane switches of rigid boards such as printed circuit boards, and are also widely used in membrane switches, contact switches, PCB boards, FPC boards, medical devices and other products.

Characteristics of metal dome:

High elasticity: metal dome can maintain stable rebound ability after repeated deformation.

Excellent conductivity: metal dome can quickly conduct the circuit when the key is pressed to realize signal transmission.

Low contact resistance: ensure good conduction effect of the circuit, reduce signal loss and energy loss.

Corrosion resistance: choose suitable metal materials (such as stainless steel), which can be used for a long time in harsh environment without corrosion.

Strong wear resistance: high hardness, strong wear resistance, can withstand long-term use without wear.

High precision: modern manufacturing technology enables metal dome to achieve extremely high size and shape accuracy.

Good stability: after rigorous design and testing, it can maintain stable performance under various working conditions.

Strong customizability: metal dome of different shapes, sizes and elasticity can be designed according to specific application scenarios.

How do you dome a piece of metal?

The main method of making a piece of metal into a dome is cold stamping through a stamping die. This method uses a die installed on a press to apply pressure to the metal material at room temperature, causing it to separate or plastically deform, thereby obtaining the required dome parts.

Steps and principles of cold stamping processing of stamping dies

Prepare materials: Select suitable metal materials, such as stainless steel or manganese materials, which have good processing properties after heat treatment.

Die design: Design the die according to the required dome shape and size to ensure that the die can accurately stamp out the required parts.

Stamping: Place the metal material on the press, and the die applies pressure to the material to cause plastic deformation or separation to form the required dome shape.

Subsequent processing: As needed, the stamped dome can be surface treated, such as nickel plating, silver plating, gold plating, etc., to improve its conductivity and corrosion resistance.

What is the strongest dome design?

The strongest dome design usually uses high-strength metal materials such as beryllium bronze, stainless steel, and spring steel.

Beryllium bronze: Beryllium bronze has extremely high strength and elasticity and is one of the preferred materials for making dome. It not only has good mechanical properties, but also has excellent corrosion resistance and wear resistance, and is suitable for various harsh environments.

Stainless steel: Stainless steel domes are usually made of high-strength stainless steel materials, such as 301 or 304 stainless steel. These materials have good corrosion resistance and high strength, and are suitable for application scenarios that require high strength and corrosion resistance.

Spring steel: Spring steel is also commonly used to make domes. These materials have excellent elasticity and strength, and are suitable for occasions that require high elasticity.

How does metal dome work?

The working principle of metal domes mainly depends on their elasticity and conductivity. Metal domes are usually located in the conductive part of the PCB board. When pressed, the center point of the dome is concave and contacts the circuit on the PCB, thus forming a loop, and the current passes, allowing the entire product to work normally.

What is an ellipse shape dome?

An ellipse shape dome is an elastic metal sheet with an elliptical outline. Its major axis and minor axis are different in size, and the edge can be smooth and curved or have chamfers, small holes, slots, etc., which are designed for easy installation and use. It is often made of elastic metals such as stainless steel, phosphor bronze, beryllium bronze, etc., and is made by stamping or CNC processing, and may be subjected to surface treatment such as electroplating.

Elliptical dome has a variety of specifications and sizes, and common sizes include 7.6*8.9mm. These dome are usually used to connect circuits, switch operations, etc. to ensure the normal operation of electronic equipment.

Based on the principle of elastic deformation during operation, it deforms along the pressure direction when subjected to force, and the deformation characteristics in the long axis and short axis directions are different, which can store and release elastic potential energy. It can provide tactile feedback and trigger circuits in electronic device buttons, and can achieve elastic contact in electrical connections to ensure circuit conduction.

What are the different metal dome shapes?

Round: The overall shape is round, with a center and annular parts, which can be evenly stressed and can be used for small pressure sensors.

Square: The outline is a quadrilateral, which can be divided into square and rectangular, and the four corners can be processed. It is used for equipment that requires precise linear deformation.

Triangle: It has three sides and three corners, with various types, and the top corner can be stressed. It is used for structures that are subjected to unidirectional force or angle guidance.

Oval: Similar to an ellipse, it has a long axis and a short axis, and the elastic properties of the two axes are different. It is suitable for equipment that requires different elasticity in different directions.

Cross: The shape is like a “cross”, consisting of two vertical long strips crossing each other, with four branches, and the end points can be stressed or fixed. It is used for equipment that contacts in multiple directions or provides elastic support.

In short, the production of metal dome requires multiple links such as material preparation, design and planning, processing and manufacturing, quality inspection, packaging and storage. Each link requires strict control of quality and process to ensure that the quality and performance of the metal dome meet the design requirements and usage standards.

What are rcg bulk tactile metal domes?

Posted on December 5, 2024 by seo_li

What are rcg bulk tactile metal domes? RCG tactile metal domes are metal parts specially designed to provide tactile feedback. Its main structural feature is its four-corner shape. This four-corner design gives the dome higher stability and reliability. It is usually made of high-quality metal materials, such as stainless steel, copper alloy, etc. These materials have good elasticity and conductivity, and can maintain stable performance under different environmental conditions.

What is the rcg dome series?

The rcg dome series refers to a group of dome products with four-corner metal domes as the main feature. The four-corner metal dome is usually a small metal sheet component, and the design of its four corners is a key structural feature. This four-corner structure makes the dome have better stability during installation and operation.

It is generally made of metal materials with good elasticity and conductivity, such as stainless steel or copper alloy. These materials can ensure that the dome still maintains good mechanical and electrical properties under repeated deformation.

From the shape point of view, except for the four corners, the main part of the dome is flat and has a certain curvature or curved shape. This shape design is to allow the dome to produce elastic deformation when subjected to vertical pressure, and the degree of deformation can be adjusted according to specific design requirements, such as by changing the thickness of the dome, the curvature size and other parameters to control its elastic coefficient.

When external force acts on the central area or other specific positions of the rcg dome, the dome will produce elastic deformation according to the magnitude and direction of the force. Since the dome itself has good conductivity, this contact will realize the conduction of the circuit. Once the external force disappears, the dome will rely on its own elasticity to return to its original shape, and the circuit will be disconnected.

In this process, the four-corner structure plays a role in stabilizing the position of the dome. The four corners can be fixed on the housing or circuit board of the device to prevent the dome from excessive displacement or distortion when it is deformed by force, ensuring the normal on-off of the circuit and the reliability of key operations.

What is a pressure switch tester?

Posted on December 4, 2024 by seo_li

What is a pressure switch tester? A pressure switch tester is a device specifically used to detect and calibrate the performance of a pressure switch. It can simulate various pressure environments and accurately measure parameters such as the operating pressure, return pressure, and switching difference of a pressure switch.

In a pressure switch, a metal dome is usually a part of a micro switch and plays a key role. When the deformation of the pressure-sensitive element is transmitted to the micro switch through a conversion mechanism, the metal dome will undergo elastic deformation according to the change in pressure. This deformation will cause the contact state of the micro switch to change, thereby achieving on-off control of the circuit.

The performance of the metal dome directly affects the accuracy and reliability of the pressure switch. If the metal dome is not elastic enough or the deformation is uneven, it may cause the operating pressure of the pressure switch to be inaccurate, or even cause misoperation or non-operation. Therefore, in a pressure switch tester, it is also very important to detect and evaluate the performance of the metal dome.

What is a pressure switch?

A pressure switch is an automatic control element that is mainly used to monitor and control pressure. When the pressure of the measured medium exceeds or falls below the preset value, the pressure switch opens or closes the contact through the deformation of the elastic element, thereby achieving control or protection of the measured pressure.

The working principle of the pressure switch is based on the elastic mechanical effect. When the medium pressure is applied to the elastic element, it will produce corresponding bending strain. By adjusting the stiffness of the elastic element and the preset trigger value, accurate control and detection can be achieved within different pressure ranges.

In the micro switch of the pressure switch, the metal dome is a common component. It mainly plays the role of assisting the on-off control of the circuit. When the conversion mechanism transmits the deformation of the pressure sensing element, the metal dome will undergo elastic deformation.

The elasticity of the metal dome can ensure that the contact state is accurately changed under appropriate pressure, and after the pressure disappears or returns to normal, it can rebound quickly to restore the micro switch to its original state.

Pressure switches are widely used in various automatic control systems, including home appliances such as air conditioners, refrigerators, and washing machines, as well as mobile equipment such as cars, ships, and airplanes. Its main function is to control or protect the corresponding system or equipment when the measured medium reaches a certain pressure.

In order to ensure the normal operation of the pressure switch and extend its service life, it is recommended to check and maintain it regularly:

Regularly check whether the contacts are in good contact: Make sure that the contacts are not oxidized or corroded, and clean or replace them if necessary.

Check the sealing performance: Make sure that the sealing ring of the switch is not aged or damaged to prevent medium leakage.

Calibrate the pressure setting value: Regularly calibrate the preset value of the pressure switch to ensure that it works within the correct pressure range.

Prevent overload: Avoid exceeding the rated working pressure of the pressure switch to prevent damage.

What is a pressure switch tester?

A pressure switch tester is a device specifically used to test the performance of a pressure switch. It simulates various pressure conditions and detects the working state of the pressure switch under different pressures to ensure that its performance meets the design requirements and usage standards.

The working principle of the pressure switch tester is based on the changes in the pressure sensor. When the pressure in the system is higher or lower than the set safety pressure, the disc in the sensor will move instantly, pushing open or close the switch connector through the connecting guide rod. When the pressure returns to the rated recovery value, the disc is immediately reset and the switch is automatically reset, thereby achieving the purpose of controlling the measured pressure.

Pressure switch testers are widely used in various industrial and automation systems to detect and control pressure. Such as:

Industrial automation: In industrial automation systems, pressure switches are used to control the flow of fluids and gases, and the tester ensures its stability and reliability under different working pressures.

Automobile manufacturing: In automobile manufacturing, pressure switches are used to control the cooling system and braking system of the engine, and the tester ensures its performance under extreme working conditions.

Aerospace: In the aerospace field, pressure switches are used to control the pressure and temperature in the cabin, and the tester ensures its reliability at high altitudes and extreme temperatures.

How do you check if a pressure switch is bad?

Turn on the pressure switch and observe whether the metal dome has signs of breakage, deformation or wear. The breakage of the metal dome is a more obvious damage. Once broken, it will definitely cause the pressure switch to not work properly. Slight deformation may affect the elasticity of the dome and the contact of the contacts, resulting in inaccurate action pressure or poor circuit contact.

Check the part where the metal dome contacts the micro switch contacts. If the contacts have obvious signs of wear, oxidation or ablation, it will affect the conductivity between the dome and the contacts. The oxide layer will increase the contact resistance, and ablation may cause the contact surface to be uneven, so that the dome and the contact cannot fit well, thus affecting the normal conduction and disconnection of the circuit.

You can use a small tool to gently press the metal dome to feel its elasticity. A normal metal dome should have obvious elastic recovery force and can quickly return to its original shape after pressing. If the elasticity of the dome is too weak, it may not provide enough force to make the contacts of the micro switch close or disconnect normally.

If there is a normal pressure switch of the same model, the elasticity of the suspected problematic metal dome can be compared with the normal metal dome. Under the same pressing force, observe whether their deformation degree and recovery speed are consistent.

What is the best way to test a pressure switch?

You can use a professional pressure calibrator, connect it to the pressure interface of the pressure switch, accurately apply pressure and compare the set value, detect the action, with high accuracy, suitable for high-precision control fields, but you need to pay attention to the interface sealing and correct operation. You can also use a simple pressure test device, which is low-cost and easy to operate, and is suitable for preliminary testing in general scenarios.

You can also use the resistance range of the multimeter to measure the normally closed and normally open contact resistances in different operating states of the pressure switch to determine the circuit connection and on-off. The operation is convenient, but before testing, make sure that the multimeter is normal and the right gear is selected, and pay attention to the electrical parameters of the pressure switch to prevent damage.

In short, the pressure switch tester is a very important testing and calibration equipment, which can ensure the accuracy and reliability of the pressure switch and ensure the safe operation of industrial production and equipment. When selecting and using the pressure switch tester, it is necessary to fully consider its function, accuracy, pressure range and other factors, and pay attention to the detection and evaluation of key components such as metal dome.
