Polycarbonate Membrane Swithes Factory Semitransparent

Membrane switch is a set of key functions, indicating components, instrument panel as one of the operating system.It consists of four parts: panel, upper circuit, isolation layer and lower circuit.Press the membrane switch, the contact on the circuit deforms downward, and the electrode plate of the lower circuit contacts conduction, after the finger is released, the contact on the circuit bounces back, the circuit is disconnected, and the circuit triggers a signal.


Membrane switch has strict structure, beautiful appearance and good sealing. With moisture-proof, long service life and so on. It was widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automotive industry, intelligent toys, household appliances and other fields.
