Abstract
The invention relates to an anti-withdrawal device for preventing a key from being withdrawn from an ignition starter switch of an automobile, comprising a blocking device which is coupled with a switch contact of a transmission. The spring-loaded blocking pin of said blocking device can be actuated electromagnetically. The blocking device acts on a detent pawl which is fixed on a rotor of the ignition starter switch and which prevents the ignition starter switch from twisting into a position in which the key can be withdrawn; depending on the position of the transmission. Said blocking device and said ignition starter switch are introduced into a steering-column switch housing that is integral with the casing tube, whereupon the blocking device locks mechanically and is electrically coupled with connection contacts of the ignition starter switch through terminal contacts, said ignition starter switch being connected by a printed circuit board in the steering-column switch housing to an electrical supply system.
