Push-button panel

Film switches are an integrated operating system that combines key functions, indicator elements, 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 contacts deform downward, making contact with the lower circuit's board for conduction. Upon releasing the finger, the upper circuit contacts bounce back, breaking the circuit and triggering a signal in the loop. Film switches are structurally sound, aesthetically pleasing, and have good sealing properties. They feature a long service life and are widely used in electronic communication and measurement instruments, industrial control, automotive industry, smart toys, household appliances, and more.
