Membrane keyboards

Grand PCB can offer you devices designed for all types of industry:

Usage of the high quality materials can guarantee the high reliability of the device allowing to use it in harsh environment. We are supplying the membrane keyboards according to military, avionics and marine industries specifications. The most advanced technologies and materials are used, providing high reliability of membrane keyboards sustaining 2.5 million operations and -50 to +70 C operating temperature.

We can offer membrane keyboards with advanced features including 0.1-0.2 Ohm contact resistance (while only 70-100 Ohms resistance is available using conductive paste) and twice much higher swithing capacity.
