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 are the Four-Leg Metal Dome Features?
The main features of the four-leg metal dome include:
1. High elasticity: The four-leg metal dome has excellent elastic properties and can maintain stable rebound ability after repeated deformation.
2. Excellent conductivity: The metal dome itself has good conductivity and can quickly conduct the circuit when the key is pressed to achieve signal transmission.
3. Low contact resistance: The contact resistance between the four-leg metal dome and the conductive contact is low, which can ensure good circuit conduction and reduce signal loss and energy loss.
4. Strong corrosion resistance and wear resistance: By selecting suitable metal materials (such as stainless steel), the four-leg metal dome can be used for a long time in harsh environments without corrosion, and has high hardness and strong wear resistance, and can withstand long-term use without wear.
5. High precision and high stability: Modern manufacturing technology enables the four-leg metal dome to achieve extremely high size and shape accuracy and maintain stable performance under various working conditions.
6. Strong customizability: Four-legged metal dome can be designed with different shapes, sizes and elasticity according to specific application scenarios to meet different needs.
What are the different metal dome shapes?
The main shapes of metal domes include round, cross, triangle, oval, waist round, etc. The diameters of these metal domes range from 3mm to 20mm, and the strength ranges from 100g to 6000gf.
Metal domes of different shapes and their application scenarios
Circular metal domes: often used in scenarios where loads need to be evenly distributed.
Four-legged metal domes: suitable for applications that require specific shapes and strengths.
Triangular metal domes: suitable for applications that require specific angles and strengths.
Elliptical metal domes: suitable for scenarios that require larger deformation space.
Waist round metal domes: suitable for applications that require specific shapes and strengths.
Metal domes are usually made of stainless steel, and can be surface treated with nickel plating, silver plating, gold plating, etc. according to needs to improve their corrosion resistance and conductivity.
Where is the rcg dome series used?
Application scenarios of four-legged metal dome include:
Membrane switches and control panels: Due to its good feel, high stroke and long life (up to 1 million times), four-legged metal dome is widely used in membrane switches and control panels.
Single-sided and double-sided, multi-layer hard boards (PCB) and flexible circuit boards (FPC): play an important role in the circuit connection of electronic devices.
Other electronic devices: such as mobile phones, tablets and other devices are also widely used in buttons and switches.
Can the rcg dome series be purchased in bulk?
It can be purchased in bulk. We provide a variety of packaging methods for bulk purchase.
Plastic box packaging: Place the metal dome in a customized plastic box, and a partition groove can be set inside the plastic box to arrange the dome in an orderly manner to avoid scratching and entanglement with each other. It is suitable for relatively small quantities and high requirements for dome protection, which is convenient for picking up and counting.
Paper envelope packaging: For some metal dome with smaller size and thinner thickness, paper envelopes can be used for packaging. The specifications and quantity of the dome can be marked on the surface of the envelope for easy identification and management. It is often used for sample gifts or small batch orders.
Foam pad tray packaging: The metal dome is placed on a tray with a foam pad. The foam can play a role in buffering and shock absorption to prevent the dome from being damaged by collision during transportation. The tray can be designed in different sizes and shapes to accommodate dome of various specifications.
Vacuum packaging: Vacuum packaging can be used. Put the dome in a vacuum bag, evacuate the air and seal it, which can effectively isolate impurities such as oxygen and moisture, extend the shelf life of the dome, and ensure its stable performance.
Coil packaging: It is packaged by winding it on a special reel. This packaging method is convenient for storage and transportation. At the same time, the dome can be easily pulled out from the reel when in use. It is suitable for automated assembly on continuous production lines, which can improve production efficiency and reduce the time and cost of manual operation.
In summary, as an important electronic component, RCG tactile metal dome has a wide range of applications in many fields such as consumer electronic devices, automotive electronic systems, medical equipment, and industrial control equipment due to its unique four-corner shape and excellent tactile feedback performance.
