Claim:
A combination air regulator and sensor assembly comprising: a head including a first chamber having an inlet and an outlet, a regulator dome including a second chamber linked with the first chamber through a bore, the second chamber including at least one outlet; a valve assembly housed within the bore and moveable between closed and open positions sealing and allowing flow in the bore; a first diaphragm positioned in the second chamber and linked with the valve assembly, the valve assembly moving in response to a pressure applied to the first diaphragm; a spring contacting the first diaphragm and applying a biasing force to the first diaphragm; a sensor dome including a third chamber linked with the outlet of the second chamber, and the sensor dome including a sensor chamber including a discharge outlet, a second diaphragm positioned in the sensor chamber, the second diaphragm including a rubber disk having a conductive contact ring attached on one side of the rubber disk and a non-conductive cup washer attached on the same side of the disk, the cup washer including a hole formed there through allowing passage of air between opposing sides of the second diaphragm; electrical contacts attached to the sensor chamber, the electrical contacts selectively engaging the contact ring and responsive to a differential pressure of the second diaphragm to define an electrical switch.
