Float switches of the type QW-xx-xx are sealed units for direct pump control.
They are intended for continuous liquid level maintenance in pools, tanks or
ponds exercised through direct control of the pumping in or out process in the
respective reservoir. They are pre-wired and depending on the chosen
configuration can control either the pumping in, or pumping out of the
reservoir. They allow direct control of single phase pumps with mounted power of
1 kW. Float switches are waterproof.
