Effect of PET film on Membrane Switch

1. What is a Membrane Switch.

Membrane Switch, also known as light touch keyboard, is a plane multi-layer integrated sealing structure and an open key panel. The sign display is sealed with the lining plate, which is a new electronic component integrating light, machine and electricity. It is a fundamental change in the appearance and structure of electronic products. It can replace the buttons of traditional discrete components, so that the operating system can complete the work of the operating system more reliably.
2. What is the structure of Membrane Switch.
The board is the "coat" of the whole membrane switch, and its main function is to play the role of sign and button. The upper and lower circuits are not only the electrical components of the Membrane Switch, but also the "shutdown" and "key" of the switch, but its performance directly affects the performance of the switching device. This method is formed by coating a layer of conductive material on the film. The upper and lower circuits are responsible for the two impact characteristics required to close the Membrane Switch. The thickness is usually 0.05-0.175mm, usually 0.125mmpet.
What are the advantages of Membrane Switch?
1. The electronic component integrating switch function and decoration function is a new man-machine dialogue interface. The connection mode between the switch circuit and the whole machine can be completed by welding or plugging.
2. The main type of Membrane Switch is a membrane switch panel, which is a plastic membrane panel with hard or flexible printed circuit board as the matrix, installed between the hand feeling and the hand feeling, and then covered with color decorative patterns.
3. Membrane Switch is waterproof. Dust proof. Oil proof. Resistant to harmful gas erosion. Stable and reliable performance. Light weight, small volume and long service life. It is easy to assemble and connect, the panel is cleaned and not easy to be damaged, and the panel is not easy to be damaged, rich in color and beautiful. The use of film switch makes your product more contemporary.
