Customized Hot Sale Membrane Switch 

Factory Customized Hot Sale Membrane Switch Since the connections of the membrane switch are prefabricated, the design of the membrane switch circuit should be submitted to the manufacturer as a process document. The design of membrane key switch circuit can be divided into two types. One is the common wire method, all membrane switches are connected to one wire, and the other end of the wire is separated. The benefit is that each contact can directly control a specific function. 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 are deformed downward, and are in contact with the pole plate of the lower circuit. After the finger is released, the contacts of the upper circuit bounce back, the circuit is disconnected, and the circuit triggers a signal.The membrane…
