New metal-over-cap technology for durable and robust switches and keypads

Schurter's new metal-over-cap (MoC) technology is the ideal solution for durable and robust switches and keypads without mechanical moving parts providing an attractive alternative to piezo switches, says the company. 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 is mounted on a rigid PCB from the rear. The MoC technology is robust against vibrations and permits use in an extended temperature range of -40to +85C. Typically, the technology can be used in building and security technology, transportation and construction machinery.
