Introduction of membrane switch

Membrane switch is an operating system that integrates key function, indicating element and dashboard. It consists of four parts: panel, upper circuit, isolation layer and lower circuit. When the membrane switch is pressed, the contact of the upper circuit deforms downwards and contacts with the polar plate of the lower circuit. After the finger is released, the contact of the upper circuit bounces back, the circuit is disconnected and the circuit triggers the signal. The membrane switch has the advantages of rigorous structure, beautiful appearance and good sealing performance. It has the characteristics of moisture resistance and long service life. Widely used in electronic communication, electronic measuring instruments, industrial control, medical equipment, automobile industry, intelligent toys, household appliances and other fields.
