Membrane Switch
A membrane switch is an interface between user and machine, enabling an operator to communicate with equipment, instrumentation, or machinery. A membrane switch is a printed electronic circuit that uses pressure to open and close a circuit. 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) along with touch screens and mechanical switches.
