The membrane switch is an operating system that integrates key functions, indicating components, and instrument panels. It consists of four parts: panel, upper circuit, isolation layer, and lower circuit.
When the membrane switch is pressed, the contacts of the upper circuit deform downwards and make contact with the plates of the lower circuit. After releasing the finger, the contacts of the upper circuit rebound back, the circuit is disconnected, and the circuit triggers a signal.
The membrane switch has a rigorous structure, beautiful appearance and good sealing performance. It has the characteristics of moisture resistance and long service life. It is widely used in electronic communications, electronic measuring instruments, industrial control, medical equipment, automobile industry, smart toys, household appliances and other fields.
