Wet-Location Foot Switches
Operate these switches hands-free when working in damp or humid environments. They’re IP and NEMA rated, so they won’t corrode when exposed to water, oil, or coolant spray.
Switches without a guard are unobstructed and let you press them from multiple angles. Switches with a guard shield the pedal so you don't accidentally step on it and activate the switch. Switches with an oversized guard fit bulky shoes and toe guards.
Two-speed switches have two contact points. Push the pedal halfway down for the slow speed or all the way down for the high speed.
Switches with a safety lever lock the pedal in place to prevent accidental activation. Fully insert your foot to release the safety lever. If the lever isn't released, the pedal won't depress.
Add an optional oversized guard to switches with or without a standard guard to shield the pedal from getting pressed by accident and to accommodate bulky shoes. Or, replace an existing oversized guard.

Variable-Speed Foot Switches
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.
