Product Description
Vacuum Switch, Snap on
The vacuum switch for the VG4 (vacuum generator 4) adapted to the vacuum generator with 4 screws on the corner of the tank. 
When vacuum in being created in the tank by the vacuum pump the diaphragm on the switch gets pulled in - once the tank reaches 8-10 inches the spring on the diaphragm is pulled in enough to release the snap action switch on the end of the assembly, turning your pump off. Once you vacuum is released from the system by flushing your toilet, the spring is released, activating your snap action switch, turning your pump on to create the vacuum lost.
One main reason for replacing your switch is if the system is building enough vacuum but your switch is not responding to turn the pump off.
When wiring the vacuum switch you will use the B terminals.
