Silicon Rubber Keyboard

These Silicon Rubber Keyboards comprise of a Snap Dome Switch and a Glass Epoxy PCB, which is used as a base and for the circuit. A layer of Silicon material covers and seals this assembly using Industrial Grade Adhesives. These type of sealed keyboards can be offered in any size and shape and are made as per customer's specifications and requirements. Silicon Keyboards can also be offered by using a carbon contact instead of a snap dome arrangement. However, in this case the overall life of the switch will be relatively lower.
