Custom Silicone Rubber Keyboard Membrane Switch 

CUSTOM SILICONE RUBBER KEYBOARD MEMBRANE SWITCH   The main function of the gasket layer is to closely connect the panel layer and the circuit layer to achieve the effect of sealing and connection. This layer generally requires a thickness between 0.02---0.05MM, with high viscosity and anti-aging properties; In production, special double-sided adhesive for membrane switches is generally used. Some membrane switches are required to be waterproof and high-temperature resistant, so the cushion layer must also use materials of different properties according to needs.   Membrane switch is an operating system that integrates key functions, indicating elements and instrument panels. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit are deformed downward, and are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of…
