A single device acts as a pressure switch, gas generated heater, and an igniter. The device has pyrotechnic material such as a combustible gas in an inner chamber. An outer chamber, that is, a chamber in which the device is positioned, includes a gas that may or may not be combustible. A monitor current flows through a pressure monitor resistor and a bridgewire resistor monitoring continuity. When the pressure in the outer chamber decreases below a threshold value, the pressure monitor resistor breaks continuity and causes a resistance change. If an air ...
A combination low pressure switch/initiator/gas generator device for a compressed gas air bag inflator comprising, first and second diaphragms each of which are electrically conducting, electrically non-conductive spacer means having a first side and a second side, attaching means attaching said first diaphragm and said second diaphragm in opposed and sealing relation to said first and second sides, respectively, of said spacer means thereby forming a hermetically sealed chamber, with said first diaphragm and said second diaphragm being movable toward an...
