Title: Initiator for air bag inflator

Abstract: An initiator (10) comprises first and second coaxial terminals (70, 80) engageable by an electrical connector (40) to connect the terminals electrically with vehicle circuitry. Electrical insulation (100) electrically insulates between the first and second terminals (70, 80). The initiator (10) also comprises a spring (150) made of an electrically conductive material. The spring (150) has a first portion (156) electrically connected with the first terminal (70). The spring (150) has a first condition, when the first and second terminals (70, 80) are not connected with the electrical connector (40), in which a second portion (160) of the spring is in electrical contact with the second terminal, thereby shorting the initiator (10). The spring (150) has a third portion (162) which is engageable by the electrical connector (40) upon connection of the electrical connector with the first and second terminals (70, 80). The third portion (162) is moved by the electrical connector (40) to move the spring (150) from the first condition to a second condition in which the second portion (160) of the spring is spaced apart from and not in electrical contact with the second terminal (80).
