membrane switch pcb

Moisture Proof Copper Foil PCB Membrane Switch , Light Weight 1. Flexibility It can be bent, folded and deformed freely. Its coil radius is small and it can be moved freely along X, Y, Z axis separately. 2. Occupy small space Since it is light and thin, it makes best use of the narrow space in the instruments. (average thickness 1.1-0. Am) 3. Light weight Its weight is very light because the design of FPC is not based on mechanical strength but current load. 4. Good seal
