A gas generator igniting capsule for use in an igniting apparatus, comprising an electrical igniter and a detonator, the electrical igniter having a contact bridge of a defined electrical resistance and two elongated contact pins of constant diameter being attached to the contact bridge; said contact pins being directed towards an igniting element within a housing with a portion of each of said pins extending axially through a concentric bore of a galvanically conductive cylindrical ring mounted in said housing, a lower portion of said pins being surrounded and supported by an insulator, said insulator being mounted in a lower end of said housing by a fitting ring; said cylindrical ring being located above said fitting ring and having a height of at least twice the diameter of the contact pins and being connected to an earth line of the igniting apparatus; said contact pin portions being separated by a distance from said cylindrical ring matched to a disruptive field strength, whereby a voltage surge occurring at the contact pin is diverted across said distance to said earth line; an insulating plug socket mountable upon said housing and surrounding said portions of said pins within the bore of said cylindrical ring, said plug socket having a cut-out portion between said pins and said cylindrical ring defining an air gap of said disruptive field strength distance between said pins and said cylindrical ring; said detonator comprising at least two detonator portions provided in the igniting capsule, a second portion being less highly explosive than a first portion; said first portion being in contact with said igniting means and being an organometallic detonator; said second portion comprising an inorganic detonator mixture; said first and second portions each being pressed into layer form and encapsulated within said capsule in a pressure-tight manner.
