The role of PET film in membrane switch-film supplier

1. What is a membrane switch? 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. Task. 2. What is the structure of the membrane switch? The panel is the 'jacket' of the entire membrane switch, and its main function is to serve as a mark and button. 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. 3. What are the advantages of membrane switches? 1. An electronic component integrating switch functions and decorative functions is a new type of man-machine dialogue interface. The connection between the switch circuit and the whole machine can be done by welding or plugging. 2. The main type of membrane switch The membrane switch panel is a rigid or flexible printed circuit board as the substrate, with or without hand-feeling buttons installed, and then covered with plastic (polycarbonate PC, polycarbonate PC, polycarbonate Ester PET, etc.) composed of film panels. 3. The membrane switch has good waterproof, dust-proof, oil-proof, harmful gas erosion, stable and reliable performance, light weight, small size, long life, convenient assembly, the panel can be washed without damage to the characters, rich in color, and beautiful Generous and other advantages.
