LF10-W series pressure switches provide reliable control for automatic water systems with time function. The switch is universally acceptable for water well pumps and pumping systems usage. LF10-WR can prevent pumps from starting while system pressure falls considerably below the cut-in pressure. It will automatically cut the water supply restoration. A manual reset lever will be decreased if system pressure is suitable for automatic operation. The simple design makes it easy to use for both professionals and normal users.
