FPC Membrane Switch Graphic Overlay 

FPC MEMBRANE SWITCH FPC keyboard membrane switch is made of flexible printed circuit, with good flexibility, light weight, stable transmission performance, impact resistance, low price, environmental protection and other advantages. Special price is only half of the ordinary rigid circuit board (PCB). Used in the key parts of the product, can reduce the cost of the product. Products are widely used in electronic machinery automation control, instrumentation, medical equipment, consumer electronics, computers, communications, measurement and household appliances, toys and other fields. 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 conta…
