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.
