Normally Open Pump Float Switch

Rainwater pumps are not designed to pump when there is
no water in a storage tank and will actually burn up if there
is not some type of protection for the pump. The switch
is wired directly through the pump to provide maximum
protection for your rainwater harvesting pump. The float
switch is preset on installation to disconnect power from
your pump before the rainwater tank completely empties.
After the next rain event, the float activates and the pump
automatically starts when there is a demand.
