Foot Switches

GENERAL INFORMATION

There are typically one of two standard foot switches on a spot welder: two stage or three stage.

• Two stage is for welders without the retraction function
• Three stage is for welders with the retract function

Linemaster 534-SWHOX Hercules Foot Switch

• $291.43 (*pricing subject to change, freight not included, please inquire for current pricing)
• Rugged cast metal enclosure has sufficient weight to keep the switch from sliding when being operating
• All models have a neoprene cover gasket plus O-rings on the activating shaft and a separate ground screw
• In all maintained contact models the release is accomplished by simply pressing the latch with a light forward movement of the toe. The release is placed under the full shield so falling objects cannot easily release it
• Oversize “O” and “OX” shield models accept oversized safety shoes and metatarsal foot guards. The “OX” shield has an additional 3/4inch (19.1 mm) opening height as compared to the “O” shield
• Painted alert orange
• single 3/4″ -14 NPT threaded conduit entry is standard
• 3 holes provided for rigid mounting to the floor or equipment

• This Linemaster 534-SWHOX Hercules foot switch is a 20 amp 125-250V, 1 HP foot switch with a heavy pilot duty of 250V maximum. It has a cast iron housing, an extra oversized aluminum guard, and neoprene (polychloroprene) gasket and O-rings for use in applications in which users need hands-free, on-and-off power activation. The foot switch provides two-stage, momentary action for push-on/push-off activation and termination. It has a cast iron treadle and housing for strength and durability, and the extra-oversized aluminum guard has 3/4″ more opening height than Linemaster’s oversized guard, for use with large-size safety shoes and metatarsal foot guards. The neoprene cover gasket and O-rings on the actuating shaft are corrosion resistant. 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 maintained operation foot switch is suitable for heavy-duty industrial and specialty medical applications, among others.20 amp 125-250V, 1 HP foot switch for use with heavy-duty electrical devices
• Cast iron treadle and housing for strength and durability
• “Extra oversized” cast aluminum guard for large-size safety shoes and metatarsal foot guards
• Two-stage, maintained action for push-on/push-off activation and termination
• Neoprene cover gasket and O-rings for corrosion resistance

*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 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.

Linemaster Switch Company manufactures electromechanical, pneumatic, digital, linear Hall effect, and wireless foot switches for use in the industrial, medical, computer, and musical fields, among others.
