Pres-Air Controls makes this vacuum pressure switch, SPDT, 125V, 25A, 250 inches of water column, and a 1/8"NPT threaded connection. Pres-AirTrol VM12540E is used on older Cal Spas, Jacuzzi Spas and Catalina Spas, among others, and replaces 47-369-2005, 610902, 9171-53, and 7132 vacuum pressure switches. This safety vacuum switch activates at 250 inches of water column by use of a rubber diaphragm. Used in front of the pump, they work to monitor vacuum pressure, as an approximation of water flow into the pump and heater - like a pressure switch, but used on the suction side of the pump, to sense vacuum pressure.
