ABSTRACT:
An ignition switch has contact plates held in a socket plate and with trip cams on the circumference of the socket plate. A switching wheel carries a plurality of contact springs, which abut on one side against a central contact and have contact arms switchable by means of the trip cams with respect to the contact plates. The contact springs also cooperate with a starter repetition lock. The central contact is in the form of a spherical shell segment and each contact spring has a spherical shell segment pressed with a prestressing force onto the spherical shell segment.
