- Membrane switch is a operating system of key function, indicating element and instrument panel brought together. Membrane switch is also named light touch keyboard, using planar multilayer combination sealing structure as a whole. It is a new type of optical, mechanical and electrical integration of electronic component. It can replace the keys of conventional discrete component , more reliably operating system tasks.
- Membrane switch panel is the main type of membrane switch, made of the basis of rigid or flexible printed circuit board, installed tactile or non-tactile buttons and plastic membrane overlay printed with colorful decorative pattern. It is a new type of human conversation interface. The connection between the switching circuit with the machine can be completed by the splicing or welding method.Printing Circuit Techinical Parameters:
