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.

Horizontal-Mount Compressed-Air Float Switches for Fuels and Oils
 |
Install these switches through a tank wall. They actuate with a compressed air valve instead of an electrical signal. Use them with diesel fuel, hydraulic fluid, oil, and water.
Fail-Open Valve—For switches with a fail-open valve starting position, the air valve closes when liquids move the float.
Fail-Closed Valve—For switches with a fail-closed valve starting position, the air valve opens when liquids move the float.

Horizontal-Mount Hazardous Location Float Switches for Fuels and Oils
 |  |
Style A | Style B |
 | |
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.
