High Quality Membrane Switch Customization

High Quality Membrane Switch Customization The basic working principle of the membrane switch is as follows: when the panel is not pressed, the membrane switch is in a normal state, its upper and lower contacts are disconnected, and the isolation layer isolates the upper and lower circuits; when the panel is pressed, the upper and lower contacts are in a disconnected state. The contacts of the circuit are deformed downward, overlap with the lower circuit and make the circuit conduct, and the circuit after the conduction sends a signal to the external connecting instrument (substrate) to realize its corresponding function; when the finger is released, the upper circuit contacts. The point bounces back, the circuit breaks, and the loop triggers a signal. 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 pr…
