Device for electrical actuation of the accelerator of an internal combustion engine, particularly of a motor vehicle, comprising a reduction gear interposed between an electric motor and an element for actuating the accelerator. The reduction gear comprises a planetary gear train whose sun gear 12 is solid in rotation with the shaft of the electric motor. An internal ring gear 11 is connected to the actuation element 4 and the planet carrier 14 is pulled elastically by a return spring 15 to actuate an electric contact switch 17.

The contactless angular displacement and/or torque pickup is characterized in that it comprises two electrically insulating coaxial disks (7a, 7b) that can turn in relation to one another by an angle to be detected and that carry on their opposing faces conductive plane coils (8) in the shape of spirally wound sectors coiled alternately in both directions and whose mutual induction varies as a function of the relative angular position of the detection disks (7a, 7b). Also included is a rotary transformer (6a, 6b) to supply one of the detection disks (7a, 7b), a circuit (18) for supplying the primary (11a) of the rotary transformer and a circuit (17, 18) for processing the signal (S) collected on one of the detection disks (7a, 7b).
