Abstract
An igniter with a charge sleeve is provided with a through hole having a cylindrical wall, a bridge wire extending at least partially within the through hole, and a consolidated ignition powder charge retained within the through hole of the charge sleeve such that the bridge wire is at least partially embedded in the ignition powder charge. The cylindrical wall comprises at least one of i) a protrusion embedded into consolidated ignition powder charge, ii) a dimple filled with the consolidated ignition powder charge, and iii) at least 2 cylindrical wall sections that are eccentric to each other. The at least one of the protrusion, dimple and 2 cylindrical wall sections positively interlock with the consolidated ignition and output powder charge to prevent the charge both from moving in a radial direction in relation to the bridge wire and from rotating in relation to the bride wire.
