Pressure Switch - Water Systems, Max 5-65 psi, Factory Setting 30-50 psi, Differential Range 15-30 psi

Furnas brand W series pressure switches provide time tested, reliable control for automatic water systems. The switch is universally accepted for use as original equipment on water well pumps or pumping systems. Its simple design makes it easy to use for professionals and non-professionals alike.

Switches combine the functions of a standard pressure switch with protection against low pressure. They prevent the pump from starting whenever the systems falls considerably below cut-in pressure. Upon restoration of the water supply, a manual reset lever is depressed until a build up of system pressure permits automatic operation.
