Abstract: The invention relates to a switch device (10), for switching a user on and off, in particular, a motor or similar in a vehicle, comprising a housing (20), an operating element (30), a switch element (40) and a display (50), wherein the display (50) is arranged on the operating element (30), the switch element (40) may be activated by the operating element (30) and at least one switch signal (117) for a control unit (15,15?) may be generated by means of the switch element (40). According to the invention, the switch element (40) is a piezo switch and the piezo switch is arranged such as to generate the switch signal (17) on pushing (31) the operating element (30) into the housing (20).

Abstract: Disclosed is an electronic steering wheel lock for motor vehicles, comprising a rotor (5) that is rotatable within a stator (2) from an initial position and back into said initial position so as to move a locking member (3) back and forth between a steering shaft-locking position and a steering shaft-releasing position. In its initial position, said rotor (5) can be coupled in a positive manner to the stator (2) under the effect of a spring load (22) while being movable within the stator (2) in an axial direction against the effect of the spring load (22) by means of an electromagnet (7) disposed coaxially to the rotor (5) in order to cancel the mutual engagement between the rotor (5) and the stator (2) and allow the locking member (3) to be moved into the steering shaft-releasing position when the electromagnet (7) is excited with the aid of an electronic key. The rotor (5) is provided with at least one coupling dog (23) which cooperates with a coupling slot (24) of the stator (2).
