What is a conductive silicone button?

We all know that silicone is an insulating material, so why are there such products as conductive silicone buttons? Let me explain for you.

First, let’s take a look at the purpose of the buttons. Buttons are devices that can control machinery and equipment, and are used to input commands and transmit information. Then the main function of the conductive silicone button is to achieve a conductive button through the conductive glue. When the conductive silicone button is pressed, the conductive rubber under the button can be electrically connected with the contact below. When the conductive silicone button is released, the button The conductive rubber underneath bounces up and does not communicate with the contacts underneath. The process of pressing and releasing achieves the purpose of transmitting information.

Silicone material itself is not conductive, so we use other methods to achieve the purpose of conductivity. One is to install conductive black particles. Place the conductive black particles in the mold before molding, and then use Teflon to shape the silicone keys first, and then perform molding. The conductive black particles will be integrated with the silicone keys. The other is to brush glue-like conductive glue on the conductive part of the silicone button that has been processed. Make it have the ability to conduct electricity. Of course, the two methods will have an effect, and there will be differences in cost.
