ABSTRACT:
A rotary position transducer for generating electrical rotary angle signals as a function of the pivoted position of a rotary device, in particular a throttle valve in the fuel supply system of an internal combustion engine, has a first carrier with concentrically disposed electric contact tracks and a second carrier with fixedly disposed wipers, which rest with axial pressure on the contact tracks. One of the two carriers is rotatable relative to the other, and the rotatable carrier has a securing element for coupling of the rotary device in a manner fixed against relative rotation. To suppress a transmission of radial and axial play of the rotary device to the arrangement of wipers and contact tracks, the securing element is joined to the carrier via a spring coupling that is torsionally rigid in the rotational direction but highly elastic in the axial and radial direction.
