PVC CNC Panel

Film switches are an all-in-one operating system that integrates button functions, indicator components, and instrument panels. They consist of four parts: the panel, upper circuit, insulating layer, and lower circuit. When the film switch is pressed, the upper circuit's contact deforms downward to make contact with the lower circuit's board, allowing conduction. Upon releasing the finger, the upper circuit contact bounces back, breaking the circuit, which triggers a signal in the circuit loop. The film switch is structurally sound, aesthetically pleasing, and has good sealing properties. It features a long service life and is widely used in electronic communication, electronic measurement instruments, industrial control, automotive industry, smart toys, household appliances, and more.
