Abstract
A pressure responsive sensor 10 for use with a vehicular air bag inflation system is shown having an electric switch 24 actuatable by a snap acting disc 40 when the gas pressure in the gas storage bottle 48 decreases to a selected low level. The snap acting disc 40 is exposed on one side to the gas mixture P1 in bottle 48 and the opposite side to a reference gas mixture P2 in a reference chamber 34. The gas mixture P2 in the reference chamber is filled to a lower pressure level than that in the bottle in order to provide switch actuation at the desired level and comprises a mixture of gases to enhance leakage testing and tracking of the pressure vs. temperature characteristic curve of the bottle gas mixture.
