- FIG. 2 is essentially based on the exemplary embodiment according to FIG. 1, the connecting device 30a on the vehicle body side now also being shown on the tape end 11 on the vehicle body side.
- the first and second conductor tracks 18, 19 are led from the steering wheel-side connecting device 30 to the vehicle body-side connecting device 30a.
- the connecting device 30a on the vehicle body side has a first connecting section 31a. In the first connection section 31a on the vehicle body side, the conductor tracks 18, 19 are connected to the contact elements 41a, 42a via the contact points 50a, 51a.
- the contact elements 41a are led out of the first connection section 31a through the plug plate 33a into the second connection section 32a.
- the second connecting section 32a on the vehicle body side forms a connector receptacle with the outgoing contact elements 41a and the connector collar 34a, so that the electrical transmission device 10 can also be contacted on the vehicle body side.
- a cable with a corresponding connector can be plugged into the connector receptacle formed in order to connect a control unit on the vehicle body side via the electrical transmission device 10 with an assembly provided on the steering wheel side.
- Fig. 3 shows a further development of the embodiment according to FIG. 2.
- the protective potential contact element 16 in addition to the conductor tracks 18, 19 and the protective potential contact element 16 in the sense of a third conductor track from the steering wheel-side connecting device 30 to the vehicle body-side connecting device 30a.
- the protective potential contact element 16 is connected to the contact element 42a via the contact point 51a.
- the contact element 42a is also from the first Binding section 31a led out through the connector plate 33a into the second connecting section 32a.
- a protective potential or the ground potential can also be applied to the protective potential contact element 16 on the vehicle body side.
