Abstract
Adapter plugs are proposed for electronic circuits in motor vehicles which normally receive plug-in units. The adapter plug is interposed between the circuits and the plug-in units and contains circuits which improve the operation of such units. Specifically, in ignition control circuits, the circuitry in the adapter plug can contain a thyristor which is normally blocked, but which shunts energy from the ignition capacitor when the ignition switch is open while the interrupter switch is closed. This prevents the generation of undesired sparks.
