About Sump, Water-Removal, Condensate, and Submersible Pumps

About Float Switches

Hang these switches in a sump pit to detect rising water levels. Use them to replace an existing switch, or pair them with a plug-in activated pump to control when the pump activates.

Voltage	Current, A	Max. Temp., °F	Plug Type	Cord Lg., ft.	Includes		Each

Heavy Duty Sewage Water Switches for Sump Pumps

Activate your pump in dirty water that contains sludge and sewage.

Dual Float Switches for Sump Pumps

If the primary float fails, the backup float kicks in and an alarm sounds to indicate float malfunction. The floats are enclosed in a mounting cage to minimize false switch activation. Use the switch to replace an existing switch, or pair it with a plug-in activated pump that operates on 15 amps or less to control when the pump activates.

Pressure Switches for Sump Pumps

Since these switches activate on increasing pressure caused by rising water levels, they have no floats to catch on sump pit walls. Use them to replace an existing switch, or pair them with a plug-in activated pump to control when the pump activates.

Switch with wire leads can be connected to a three-pronged plug or wired directly to a power source.

Drop-In Float Switches for Water

Switch with ABS
Plastic Float and
Three-Prong Socket

Switch with
Polypropylene Float
and Adjustable Level

Hang these free-floating switches in your tank for water-level monitoring that doesn’t require installation through a tank wall.

Switches with three-prong socket allow you to plug your pump directly into the switch; the socket piggybacks to the three-prong plug. They’re often used to trigger an alarm.

Switches with adjustable level prevent excessive switch activation in tanks with fluctuating level. Adjust the set point by moving the weight along the cable or altering the cable length.
