Product Description

Membrane Switch

Membrane switches, also called membrane keypad, are built from thin polyester film and pressure sensitive adhesive (PSA). Printed Circuit Boards (PCBs) can also be used as the base for a switch. Membrane switches can be tactile or non-tactile, depending on the design. Tactile switches provide a physical "click" when the user pushes it. Non-tactile switches have longer lives, but lack physical feedback to the user. Rubber keypads can be added to the top of the membrane switch as well.
