Float Switches for Sump Pumps
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.
Heavy Duty Sewage Water Switches for Sump Pumps
Activate your pump in dirty water that contains sludge and sewage. This switch has no moving parts for a longer life than float switches. Use it to replace an existing switch, or pair it with a plug-in activated pump to control when the pump activates.
| Voltage | Current, A | Temperature Range, °F | Plug Type | Cord Lg., ft. | Each | |
| 120V AC | 12 | 35° to 120° | Three Prong | 15 | 0000000 | 0000000 |
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.
| Voltage | Current, A | Max. Temp., °F | Plug Type | Cord Lg., ft. | Features | Includes | Each | |
| 120V AC | 12 | 100° | Three Prong | 4 | Mounting Cage | Stainless Steel Clamp | 0000000 | 000000 |
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.
Oil-Detection Switches for Sump Pumps
To prevent contamination, these switches won’t activate if they sense oil in your sump pit. They have a probe to detect the liquid level—it activates when it senses water and deactivates when it senses oil. Use these switches to replace an existing switch, or pair them with a plug-in activated pump to control when the pump activates.
| Voltage | Current, A | Temperature Range, °F | Plug Type | Cord Lg., ft. | Specifications Met | Each | |
| 120V AC | 16 | 35° to 170° | Three Prong | 20 | CE Marked, UL Listed | 0000000 | 0000000 |
Drop-In Float Switches for Water
Plastic Float and
Three-Prong Socket
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.

Float Switches for Slurries and Thick Liquids
Switch With
Adjustable Level
A polypropylene float makes these switches buoyant even in viscous liquids. Hang them in your tank for level monitoring that doesn’t require installation through a tank wall.
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.
