A chip slapper is presented, having a substrate, a conductive layer disposed above the substrate face, and an intermediate layer disposed between the substrate face and the conductive layer. The conductive layer and intermediate layer form a first land and a second land atop the substrate face, with a bridge formed of the intermediate layer spanning between the first land and the second land. A first adhesion portion is attached to the first land, and a second adhesion portion is attached to the second land, wherein at least a portion of the bridge is not overlaid by the first adhesion portion or the second adhesion portion.

A ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, for example for devices which are subjected to high pressures, such as igniters for airbags or belt tensioning devices, includes a feedthrough opening, whereby the feedthrough opening is located substantially in the center of the ring-shaped or plate-like element and whereby the ring-shaped or plate-like element has a thickness. The ring-shaped or plate-like element has a relief region in the area of the feedthrough opening. Further, the ring-shaped or plate-like element in the relief region has at least one thickness which is reduced by the height of the relief region and which is selected so that the feedthrough opening can be punched out of the ring-shaped or plate like element having the reducing thickness.

An initiator for a gas generator of a vehicle safety device includes a cup defining an interior, a primary pyrotechnic material disposed in a primary combustion chamber in the interior of the cup, and a pair of electrical pins in reaction initiating communication with the primary pyrotechnic material through a bridge wire. The bridge wire is in reaction initiating contact with the primary pyrotechnic material at a first end of the primary pyrotechnic material. The primary pyrotechnic material is compacted within the primary combustion chamber to include a depression at a second end of the primary pyrotechnic material, the second end opposite the first end.

A pyrotechnic ignition pill with a housing, an ignition pill charge housed in the housing, at least two terminal contacts connected to the ignition charge, wherein the terminal contacts are guided out of the housing through a glass bushing, characterized in that the terminal contacts in the region of the ignition charge have a round cross-sectional profile and that the terminal contacts outside the housing have an angular cross-sectional profile.
