• What is a Membrane Switch?
• A membrane switch or flat panel switch consists of a printed polyester or polycarbonate overlay adhered to a printed circuit using pressure to open and close a circuit. The switch is an interface between user and machine, enabling an operator to communicate with equipment, instrumentation, or machinery. The membrane switch circuitry is most often screen printed using conductive inks which are typically made of silver or carbon. Membrane switches are part of a range of devices considered to be user interfaces or human machine interfaces (HMIs).
