Abstract
Description
Technical Field

[0002] A membrane switch is an operating system that integrates key functions, indicator elements, and instrument panels. It consists of a panel, upper circuit, isolation layer, and lower circuit. When the membrane switch is pressed, the contacts of the upper circuit deform downward, contacting and conducting with the plates of the lower circuit. When the finger is released, the contacts of the upper circuit rebound, breaking the circuit and triggering a signal. Membrane switches feature a rigorous structure, attractive appearance, good sealing, moisture resistance, and a long service life. They are widely used in electronic communications, electronic measurement instruments, industrial control, medical equipment, the automotive industry, smart toys, and household appliances.
