The LF10-W series pressure switch can continuously measure and control the pressure of automatic water supply systems. This series of pressure switches is widely used as a matching component in water pumps or other water supply systems.
LF10-WR can prevent the water pump from starting and running below a certain water pressure, and the switch will automatically close when the water pressure returns to the preset value. The switch with a handle can be manually operated to turn on and operate the system, making it easy to use.
