Abstract
An igniter for propulsion unit including a receptacle having at least one opening through which passes a conducting line connected to an ignition carrier of a slapper contained within the receptacle, the igniter being characterized in that at least one elastomer material is disposed between the ignition carrier and the opening such that the pressure of the gases generated by the propulsion unit which is ignited pushes the elastomer material at the vicinity of the opening of the receptacle so that this elastomer material blocks the opening and avoids any gas leak through this opening.
