Membrane Switches

Fun Fact:

Nintendo makes a game called “Membrane” for playing on its Switch gaming system. . . and you couldn’t play Membrane on Switch without membrane switches.

We all encounter membrane switches every day, when we tap a computer keyboard, program a microwave oven, choose something to watch with a remote control, or pump gas. A membrane switch protects a control mechanism from moisture, soil, and other environmental elements that could interfere with the performance of the switch. This is especially valuable in settings and applications where the mechanism could be exposed to chemicals or similar hazards. PET (polyethylene terephthalate) film delivers a wealth of critical properties that make it the material of choice for membrane switches: high tensile strength, a wide variety of thicknesses, chemical resistance and electrical insulation.
