Abstract

An igniting element, such as is used in a vehicle air bag igniter reduces the power dissipated by the air bag ignition circuit, as well as its space requirement and its costs, by using the ignition switch/switches as the ignition element (7) itself of the ignition circuit. The ignition circuit is integrated in a silicon chip, and has at least one ignition switch constructed as a transistor.
