Membrane Switch 0111
A membrane s witch typically has 4 or more layers. The top layer of a membrane switch is the graphic interface between the user and the machine. The another critical layer is a printed circuit. This can also be a flex circuit made of copper and polyimide material. The layers are normally assembled using pressure-sensitive adhesives although inexpensive designs can be held together by other mechanical means such as a keyboard housing. Contact between two traces can be made through a printed shorting pad or through a metal dome that stands on legs.
