LF10-W series pressure switches provide time-tested, reliable control for automatic water systems. The switch is universally acceptable for use as original equipment on water well pumps or pumping systems.

LF10-WR can prevent the pump from starting whenever the system falls considerably below the cut-in pressure. Upon the restoration 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 non-professionals alike.
