About Electrical Switches

Choose a switch with the right trigger type, number of inputs, and control functions to power your equipment.

Wet-Location Foot Switches


Switch	Switch with Guard

Switch with Oversized Guard	Switch with Safety Lever and Oversized Guard

Operate these switches hands-free when working in wet or humid environments. They’re IP and NEMA rated, so they won’t corrode when exposed to water, oil, or coolant spray.

Oversized Guard—Switches with an oversized guard fit bulky shoes and toe guards.

Safety Lever—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.

With Guard—Switches with a guard shield the pedal so you don't accidentally step on it and activate the switch.

Without Guard—Switches without a guard are unobstructed and let you press them from multiple angles.

2 Speeds—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.

Switch Guards

Add an 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.

Horizontal-Mount Hazardous Location Float Switches for Fuels and Oils


Style C

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” or from “on” to “off”.

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