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.
Voltage | Current, A | Temperature Range, °F | Plug Type | Cord Lg., ft. | Each | |
120V AC | 13 | 35° to 140° | 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.

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.

Medium-Pressure Switches for Well Water Pumps

- For Use With: Water
- Connection Material: Steel
- Connection: NPT Female
- Switching Current: 24A/34A
- Switching Voltage: 120V AC/240V AC
These switches meet the pressure and electrical requirements of well water pumps. They electrically activate automated controls or alarms when a set pressure is reached. Switches are double pole, single throw and normally closed (DPST-NC), so they switch two circuits from on to off.

Tilt Switches





Often used as position indicators, pump level controls, and machine limit switches, these switches actuate when tilted to a certain angle. They mount horizontally and activate when tilted downward, and deactivate when tilted up. Differential angle is the total angle from the point of activation to the point of deactivation. All combine electromechanical and solid state technologies for reliability and long life.
