ABSTRACT:
A short-circuit fuse for electrical igniters with a plug-in connection wherein the short-circuit is automatically eliminated upon a connection of the igniter to a current carrying line. At least one pin-shaped electrode, extending out of the igniter, is surrounded by a common socket with at least one contact spring, arranged at the socket and extending essentially in parallel to the at least one electrode, being normally in contact with the electrode when the igniter is unconnected to the current carrying line. The contact spring has an elongated and leaf-like shape and is electrically conductively connected with either a further contact spring or with the igniter casing. Upon a connection of the igniter to the current carrying line, the contact spring is lifted off the electrode by the insertion of a connector plug.
