The LF37 diaphragm pressure switch is available for various sump pumps, 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 traditional float ball mechanisms. The port connection design allows it to sense the pressure without immersing it in the liquid directly.
