Anti-static membrane switch has the same structure as other membrane switches. It is composed of graphic overlay, metal domes, circuit and back adhesive. The raw materials are also the same, such as films, inks, silver paste and LED.
We put a layer of conductive metal material on graphic overlay, and connect it to the casing. This layer is also called electrostatic net.
Static electricity may generate on the surface of film. The electrostatic net can effectively lead it to the casing. As a grounding device, the casing can safely lead static electricity into the ground, thereby preventing static electricity from damaging membrane switches or other electronic equipment.
We can see anti-static membrane switches on some complex instruments. They are also used in high-risk working conditions, such as flammable and explosive environments under coal mines, or flour production.
