PS04-W Water pressure switches provide time-tested, reliable control for automatic water systems. The Water Pressure switch is universally acceptable for use as original equipment on water well pumps or pumping systems.

PS04-WR Water pressure switch prevents the pump from starting whenever the system falls considerable below cut-in pressure. Upon the restorations of the water supply, it will automatically cut-in.
A manual reset lever is depressed until a build up of system pressure permits automatic operation. Its simple design makes it easy to use for professionals and nonprofessionals alike.
