LF10-W

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 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. Or a manual reset lever is depressed until a build up of system pressure permits automatic operation. It simple design makes it easy to use for professionals and nonprofessionals alike.
