Applications

Membrane switches are used in many consumer products as well as many industrial applications.

Some of the most common applications for a membrane switch include:

  • medical equipment
  • industrial control panels
  • retail equipment
  • instrumentation
  • household appliances
  • consumer products

Household appliances like microwave ovens and stoves are operated by membrane switches. Vending machines, kiosks, exercise equipment, and gasoline pumps are other common retail/consumer applications. In industry, any manufacturing equipment can have a control panel with a membrane switch. Medical test equipment and HVAC controls are also good examples of uses for membrane switches.
