Abstract
An operating device for a steering wheel comprises an operating element, which can be selectively rotated about a first rotation axis and a second rotation axis for controlling a control system by means of an actuation, wherein the operating element can be rotated to an actuation stage from a starting position, wherein the first rotation axis is coaxial to the longitudinal axis of the operating element, and the second rotation axis is substantially transverse to the first rotation axis, wherein a force application point has a mechanical advantage with respect to the second rotation axis when actuated about the second rotation axis, and wherein the force application point has no substantial mechanical advantage in relation to the second rotation axis when the operating element is actuated about the first rotation axis, in order to prevent a simultaneous actuation of the operating element about the first and second rotation axes.
