This Linemaster 511-BG Hercules Anti-Trip 20 amp 125-250V, 1 HP foot switch has a heavy pilot duty of 250V maximum. It has a cast iron housing, oversized aluminum guard, and a non-trip mechanism for use in applications in which users need hands-free, on-and-off power activation. The foot switch provides single-stage, momentary operation for quick-release termination. It has a cast iron treadle and housing for strength and durability and an oversized aluminum housing for large-size safety shoes and metatarsal foot guards. The neoprene (polychloroprene) cover gasket and O-rings on the actuating shaft are corrosion resistant. An anti-trip treadle mechanism helps prevent power flowing to the device or equipment if a user accidentally steps on the treadle. The non-skid base prevents the foot switch from sliding on smooth floors and has 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 meets Canadian and United States Underwriters Laboratories (UL) standards for quality assurance. It has an Ingress Protection (IP) rating of 56 for protection against contact with live parts and damaging deposits of dust and protection against heavy seas, and it is compliant with the Restriction of Hazardous Substances (RoHS) directive. This momentary operation foot switch is suitable for heavy-duty industrial and specialty medical applications, among others.
*H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.
Foot switches are used to turn on and off electrical devices and may also provide control over the devices 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 devices 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.
