A novel hybrid air bag inflator system includes a differential pressure monitoring switch which comprises a sealed module containing a gas under a threshold pressure mounted in a gas bag filler tank. The capsule comprises a movable diaphragm connected to a fixed top plate and the diaphragm is supported on a shaped mandrel mounted on a switch body. The switch body and the mandrel are provided with a central aperture through which moves a movable piston and the movable piston forms a support for switch contacts which are normally open until the pressure P1 in the hybrid air bag gas filler tank falls below a predetermined operable reference pressure P at which time the switch contacts reach a closed position indicative of a failed or inoperative hybrid system.
A method of assembling a differential pressure switch for installation in a hybrid air bag inflator system of the type comprising a cylindrical tank containing an inert gas at predetermined pressure P1 for use in inflating an air bag comprising the-steps of:
