ABSTRACT:
This device for transmitting data, coming from a plurality of control elements (8 to 11) mounted on a steering wheel of a motor vehicle, to a system recognizing the data and also mounted on the vehicle, comprises light sources (12 to 15) mounted on the steering wheel and respectively connected to the control elements. The light sources are disposed in such manner as to cooperate with annular means (16 to 19) coaxial with the steering wheel for transmitting light to photosensitive detectors (30 to 33) mounted on the vehicle and adapted to actuate loads corresponding to the actuated control elements, irrespective of the position of the light sources relative to the photosensitive detectors.
