LF37 diaphragm pressure switch is available for various sumps, effluent, and sewage applications to control the liquid level.
Various switch settings are available to turn on or turn off the pump.
The diaphragm pressure sensing design makes it more reliable than the traditional float ball mechanism.
Port connection design means it can sense the pressure without immersing the liquid directly.
