LF10-W Water Pressure Switch (15 -150 PSI)
Product Details

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.
