Sump Pump Switches — AC Rated
These completely molded,
ruggedly constructed switch
assemblies are designed
specifically for sump pump and
liquid level applications. All series
feature Quick-make/Quick-break
mechanisms with snap acting butt
contacts. They provide high
reliability and long life at an
economical cost. Currently used in
many pedestal and submersible
type residential sump pumps,
these switches can be supplied to
operate with float type or weight
type actuators.
