[0002] The membrane switch is an operating system that integrates key functions, indicating elements, 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 downward and contact and conduct with the plates of the lower circuit. When the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the loop triggers a signal. It has the characteristics of small size, good quality, and strong protection. It is widely used. During its processing, the surface of the membrane needs to be coated with double-sided tape.
