Abstract

An electrical ignition device (1) has a metal container (2) for a firing resistor or bridge, a first (3) and a second (4) terminal pin and at least one ignition charge (5, 6). So that firing of the ignition charge does not occur in the event of electrical discharges between terminal pins and a housing, it is proposed that the container (2) be capable of being embedded in a plastic material by injection moulding and inserted in the housing, that a first outward extension (8) be provided on the container (2) which is electrically conductively connected to the first terminal pin (3), and that a second outward extension (9) be provided on the container (2) which can be formed so as to extend to the housing leaving a small clearance and of which an outer end is not embedded in the plastic material.
