Drop-In Float Switches for Water


ABS Float with Three-Prong Socket	Polypropylene Float with Adjustable Level

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

Three-Prong Socket—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.

Adjustable Level—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.
