NOTE: This switch is not recommended for controlling electrical loads less than 100 milliamps, 12 VAC or non-arcing electrical loads. This switch must be used with pumps that provide integral thermal overload protection.
A Pump Switch is designed for Horsepower (HP) rated loads and is not suitable for control (pilot duty) applications. It will fail prematurely when switching loads less than 1 Amp at 120 VAC. Select a float switch from our Control Switch offering for control applications.
