Schurter's new Metal over Cap (MoC) offers a solution for durable and robust switches and keypads without mechanical moving parts.

This capacitive MoC technology is a good alternative to piezo switches. This robust switching panel is designed for use in harsh environments and can be equipped with front plates of stainless steel or aluminium. The customer-specific graphical printing of the surface design is made by screen printing with an additional protective coating. The sensor electronics with common communication interfaces are mounted on a rigid PCB from the rear. The MoC technology is robust against vibrations and will operate in an extended temperature range from -40 to +85°C.
