The membrane switch is an operating system that integrates key functions, indicating elements, and instrument panels. By the panel, the upper circuit, isolation layer, the lower circuit consists of four parts. Press the membrane switch, the upper circuit contacts downward deformation, and the lower circuit of the pole plate contact conduction, finger release, the upper circuit contacts rebound back, the circuit is broken, the circuit triggers a signal.
Membrane switches have been widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.
