Membrane Switch Features

The membrane switch is an operating system that integrates the button function, the indicator component, and the instrument panel. 

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 is deformed downward, and the contact with the plate of the lower circuit is turned on. 

After the finger is released, the upper circuit contact bounces 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 anti-moisture and long service life. Widely used in electronic communication, electronic measurement instruments, industrial control, medical equipment, automotive industry, smart toys, household appliances and other fields.

Membrane switches, also known as light touch keyboard or keypad, is a mechanism keypad, a one-piece combination of flat and multi-layered sealing structure. 

It is a kind of light collecting, machine and electric integration that seals the key switch, panel, mark, symbol display and liner. 

The new electronic components are fundamental changes in the appearance of electronic products. Membranes can replace the buttons of conventional discrete components and perform the tasks of the operating system more reliably.
