Silicone Rubber Keypad
Silicone Rubber Keypads - The economic option for your applications
The silicone rubber keypads contacts are relatively economic and reliable option when compare to membrane switches or other material, because it's made of high elastic, nontoxic silicone rubber compounds that can be massive produced by compression or injection modeling. The ease-shaped silicone rubber keypads provide great convenience for integrating with the printed circuit boards (PCB) in any form. Moreover, the sensitivity and the tactile feedback can be adjusted to satisfy the operator's need. Due to its excellent characteristics, the silicone rubber switch is utilized in various industries to satisfy cost, reliability, and ergonomic/ cosmetic styling needs.
