Electromechanical Vacuum Switches
The Presair Electromechanical Vacuum Switches is a general purpose vacuum switch with a user adjustable set-point and small switching differential. This diaphragm operated vacuum switch is high vacuum compatible. The electromechanical vacuum switch contains a pressure sensitive diaphragm which operates a non latching snap action microswitch. The switch can be used to operate an electrical circuit when the system pressure rises or falls through an operator-determined pressure set point between 2.5 to 300 inches of water.
Spas, whirlpools, jetted baths and hot tubs incorporate Presair’s high quality, UL approved switches and controls. Other important applications are medical equipment, plumbing and HVAC equipment and products for the home.
