The vacuum switch is an electrical device wired intothe power circuit to an electric motor or electric clutch.When the switch is connected to the suction side of a pump,it senses the break in vacuum if the pump runs out of liquid.The break in vacuum causes the switch to open the circuitand shutoff the motor or deactivate the clutch.
The vacuum switch is generally installed in a pumpingsystem when transferring or pumping a limited amount ofliquid when the pump cannot be attended at all times. Theswitch provides automatic shutoff when the pump runsdry, helping to prevent damage to the pump. Normally,the switch is manually restarted, although it is possiblewith electric motor and clutch installations to wire amomentary switch, float or liquid level device across theterminals of the vacuum switch to reactivate the systemremotely or automatically.
The switch is normally mounted on the inlet side of thepump, between the pump and liquid source. The switchcontains a spring loaded diaphragm sensitive to a vacuumof not less than 4-1/2" Hg (mercury).
