Abstract
An actuating device () for a technical system, especially for selecting gears of a shift-by-wire speed-change gear includes an actuating element () with at least two shift positions and a locking device (). The locking device () has at least one actuator () driven with auxiliary energy and is used to reduce the shifting path of the actuating element () or to lock the actuating element (). The actuator () has at least three different shifting states to make it possible to embody the necessary locking functions of the actuating lever with a reduced number of actuators and hence with a comparatively low design effort. Space, weight and costs can thus be saved.
