Foot switches are used to turn on and off electrical devices and may also provide control over the device's speed and mode of operation. They come with up to three pedals and can have a maintained, momentary, variable, or anti-trip switch action. For maintained action switches, one press of the pedal controls the power, whereas momentary action switches require constant pressure on the pedal for power. Variable action switches (also called foot potentiometers) function similarly to momentary action switches, but also provide control over the connected device's operating speed. Anti-trip action switches require users to release a safety latch before pressing down for momentary action. Foot switches vary in their contact specifications, amp ratings, plugs and receptacles, and material construction to suit different applications, device amperages, plug configurations, and environments. Foot switches are commonly used with power tools, sewing machines, musical instruments, dental equipment, and lighting, and in the construction, laboratory, production, and medical fields, among others.
