ABSTRACT:
An air bag inflator (20) includes gas stored at or above a predetermined pressure in a chamber (24) in a container (22). An initiator (10) connected with the container (22) is exposed to the pressure of the gas stored in the chamber (24). A closure can (120) of the initiator (10) includes an electrically conductive sensor portion (140) which is spaced apart from an electrically conductive contact can (200) when the pressure in the chamber (24) is at or above the predetermined pressure. If the pressure in the chamber (24) drops below the predetermined pressure, the sensor portion (140) moves into electrical contact with the contact can (200). The engagement of the sensor portion (140) with the contact can (200) completes an electrical circuit to provide an indication of low pressure in the inflator (20).
