Most companies today have completely different production methods from before. Designers and engineers build products with enhanced functionality and a stronger user experience by combining the various materials and components used in the production of the product. And the metal dome switch is one of these components, the tactile dome switch.
What is a dome switch
Tactile dome switches, also called snap domes or metal domes, are instantaneous contacts. Tactile dome switches are buttons with their own circuits. They are made of PET material and have text and patterns for prompts. The metal dome is installed inside and assembled with PCB or FPC. When you press the key part on the surface with your finger, the key contact is electrically connected to the corresponding part of the contact point on the lower part, thereby transmitting instructions.
Advantages of dome switches
Tactile dome switches provide many conveniences in product application. Tactile dome switches are easy to install and affordable, which makes Tactile dome switches very popular among manufacturers in large-scale mass production. At the same time, Tactile dome switches provide efficient and accurate tactile feedback in applications, allowing users to convey instructions better and faster, and at the same time allowing users to trigger specific operations.
Since the Tactile dome switches have a sealed structure as a whole, the contacts of the switches are not corroded by harmful gases, are not easily oxidized, and are waterproof and dustproof. Therefore, in normal applications, the service life of the Tactile dome switches can be optimal, and the metal dome The service life has been tested and can reach 5 million times. The dome avoids dust infection in the Tactile dome switches and can minimize damage. Therefore, the normal use of Tactile dome switches will not be affected in harsh environments.
Common applications
Tactile dome switches are widely used in industry, machinery, electronic appliances, medical treatment, instrumentation and many other fields. Although Tactile dome switches are involved in different application fields, the functions in various applications are the same. However, combined with the requirements of different industries, the methods of producing and designing metal domes are different.
In industrial applications, it is installed on equipment to switch and transmit instructions. This requires Tactile dome switches to have good waterproof, oil-proof, anti-static interference and other functions to avoid operation, which will affect the use effect during installation and use.
In the medical industry, it can be used in various instruments and equipment, such as medical monitoring instruments, surgical instruments, and electronic medical equipment. Doctors need to use a variety of different instruments to complete surgical operations. Tactile dome switches can be integrated on the handle or button of the instrument, and the doctor can control the operation of the instrument by pressing the switch. Tactile dome switches have requirements for product precision and feel during production. Due to the particularity of the use environment, the products must be strictly controlled.
Choose the right dome switch
When choosing a suitable Tactile dome switches manufacturer, the first thing to do is to combine the performance of the manufacturer’s products with the actual application. Best Technology has good insulation, heat resistance, bending resistance and resilience, and does not affect use in some special environments. Set the size of Tactile dome switches according to the actual application size to make the product more suitable for the application.
