Membrane Switch

 

Membrane switches are thin and flexible switches and are economical alternatives to conventional mechanical switches, offering a sealed construction and improving the overall appearance. A membrane switch works by permitting the momentary opening and closing of a circuit. Pressing the keypad button activates the circuit. This causes the switch contacts to connect and permit continuity and current flow. The connection or circuit is broken as soon as the button is released.

Graphics Connection offers Membrane Switch production engineering. Engineering includes production drawings, circuit layout and tooling designs.
