This Linemaster TWIN 88SN1-05 Classic IV twin foot switch is a 16 amp 125-250V, 1/2 HP dual foot switch assembly with aluminum housing, base plate, and waterproof design for use in applications in potentially wet environments where users need hands-free, on-and-off power activation. The foot switch provides single-stage, momentary operation for quick-release termination. It has a one-piece cast aluminum housing for durability and resistance to corrosion. The switch has a pedal divider for safety and provides an aluminum base plate with non-skid feet and bolt holes for mounting to the floor or equipment. It has a 3/4″-14 National Pipe Taper (NPT) threaded conduit entry for wiring. This foot switch assembly meets Canadian and United States Underwriters Laboratories (UL) standards for quality assurance and meets European Conformity (CE) product compliance safety standards. It has an Ingress Protection (IP) rating of 68 for total dust ingress protection and permanent submersion in water, an International Electrotechnical Commission (IEC) rating of 601-2-2 for the safety of high-frequency medical electrical equipment, and is compliant with the Restriction of Hazardous Substances (RoHS) directive. A heavy gauge steel guard and other accessories are available for this product (contact manufacturer). This momentary operation foot switch is suitable for medium-duty applications in the medical field and light industry, among others.

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.
