Membrane switches have long been the industry standard in a variety of different applications and can be found across a wide range of industries. Simply a mechanical switch that is used in order to complete a circuit, the membrane switch is often the first choice when an economical, robust user interface is required. A typical membrane switch is a momentary, normally open switch created using a conductive stainless steel dome and its contact with a conductive printed circuit. The combination of the low-profile dome and flat printed silver circuit allow the membrane switch to used where little space is available, making it ideal for a wide variety of applications. Membrane switches can be arranged in a combination of individual circuits; schematic diagrams frequently feature common power or common ground connections which can reduce the total number of contacts (traces) required. Membrane switch circuits can also be arranged using an X,Y matrix, allowing functionality well beyond the total number of dome switches. Other electronics can be embedded within the laminated layers of the membrane switch, including low-profile indicator LEDs, LEDs for backlighting and other illumination requirements, resistors and potentiometers.
