waterproof membrane switch with LED and Metal dome FPC circuit
What is Membrane Switch keypads?
Membrane switch is an operating system which integrates key function, indicating element and instrument panel. It consists of panel, upper circuit, isolation layer and lower circuit. Press the membrane switch, the contact of the upper circuit is deformed downward, and the contact with the electrode plate of the lower circuit is conductive.
When the finger is released, the contact of the upper circuit bounces back, the circuit is disconnected, and the circuit triggers a signal. The membrane switch has strict structure, beautiful appearance and good sealing performance. It has the characteristics of moisture-proof and long service life.
It is widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, intelligent toys, home appliances and other fields.
