Abstract: The invention concerns a steering column assembly switch for automotive vehicles with a supporting sleeve surrounding the casing tube of a steering mechanism and mountable thereon, supported by means of a roller bearing on the steering column and housing a plurality of switches, the sleeve having a hollow cylinder mounted at an acute angle to the axis of the sleeve, for a column lock and an ignition switch. The plurality switches are located in a common housing mounted on the supporting sleeve concentrically to the axis of said sleeve. The internal space is divided into two chambers by means of an annular disk and on both sides with conductor bars and switch contacts; each of the chambers contains an annular, rotatably and tiltably mounted sliding contact with a switching lever.

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.
