What is the function structure of PET film in the membrane switch? -Film supplier

PET membrane switch, also known as light touch keyboard, adopts a flat multi-layer combination of integral sealing structure, which combines key switches, panels, and marks. A new type of electronic component that integrates light, machine, and electricity with the symbol display and the backing plate sealed together. It is a fundamental change in the appearance and structure of electronic products. It can replace the buttons of conventional discrete components and execute the operating system more reliably. The task; the panel is the 'jacket' of the entire membrane switch, the main function is to play the role of markings and buttons. The upper and lower circuits are the electrical components of the membrane switch, which is also the 'close' and 'key' of the switch, but its performance directly affects the performance of the switch device. It is formed by printing a layer of conductive material on the film. The upper and lower circuits are responsible for the two shock characteristics required for switch closure. The thickness is generally between 0.05-0.175MM, the most common is 0.125MM PET.
