ABSTRACT:
An ignition unit for igniting propellants having at least one electrically conductive pin with a pin holder comprising a metal ring which encloses the pin by leaving an annular cavity with an insulating filing in the annular cavity. An electrically conductive bridge or a semi-conductor bridge connects between the metal ring and the pin with a sealing cap which is connected to the one face side of the pin holder and which receives the propellant. A plug can be connected in a positive or non-positive way with the metal ring on its end averted from the sealing cap and which enters into an electrically conductive connection with the pin in operation. At least one of the two elements, either the metal ring or the plug are provided with a coating in the region between the mutual connection, which coating has a low electric contact resistance between the plug and the metal ring.
