Warrick-Gems Sensors & Controls 164870 Float Switch S.S.

The Warrick-Gems Sensors & Controls 164870 Float Switch S.S. is a liquid-level control device found in a variety of HVAC equipment, such as sump pumps, condensate drains, and chilled water systems. Its body is made of strong stainless steel, and its float is composed of stainless steel that floats. A magnetic reed switch that opens or closes an electrical circuit is triggered when the float lifts in response to an increase in liquid level. By automatically adjusting pump operation based on liquid level, this straightforward yet efficient technique helps avoid overflow, system damage, and possible environmental risks. When a sump pump is used, for example, the rising liquid level raises the float, which activates the pump and removes extra water. However, when the liquid level falls, the float also does, turning off the switch and halting the pump.
