Wet-Location Foot Switches

With Guard

With Oversized Guard

Safe for use in wet locations, these switches are IP and NEMA rated for protection from corrosion, washdowns, and oil/coolant spraying.

Two-speed switches have staged contacts. For slow speed, push the pedal halfway to close the first contact; for high speed, push it all the way to close the second contact.

Switches with an oversized guard accommodate bulky footwear.

Switches with a safety lever prevent accidental activation; the lever must be pushed forward before pressing the pedal.

Variable-Speed Foot Switches

Iron

Iron with Guard

When the pedal is pressed, the built-in potentiometer adjusts the resistance to vary the speed for motor drives. These switches can be wired to either increase or decrease the current when actuated. All are rated NEMA 4 and 13 for protection from washdowns and oil/coolant spraying.

Horizontal-Mount Hazardous Location Float Switches for Fuels and Oils

Designed for use in areas where flammable substances are present, these switches are CSA certified for hazardous locations. Mount them through a tank wall. All are rated NEMA 4 for protection from washdowns. All are single pole, double throw (SPDT) and can be installed to turn one circuit from “off” to “on” (normally open) or from “on” to “off” (normally closed).

Switches with stainless steel body are more corrosion resistant than switches with brass body.
