Abstract
A connection part for an ignition device, arranged between an ignition coil and a spark plug for incorporating in a cylinder head of an internal combustion engine, has an isolation housing, a high voltage switching element located in the isolation housing and during application of a trigger voltage is transferred reversibly in an electrically jump-like fashion to an electrically conductive condition, a first junction element located at one end of the high voltage switching element and connected with one pole of the latter and also connectable with a high voltage terminal of the ignition coil which leads to an output voltage of the ignition coil, a second junction element provided at another end of the high voltage switching element and connected with another pole of the latter and provided for receiving a terminal pin of the spark plug, and an element associated with the isolation housing for increasing a capacity region between the high voltage switching element and the first junction element.
