Actuator with rotary switch

The invention relates to an actuating device for a technical system, in particular for a shift-by-wire change gear transmission. The actuating device comprises an actuating element (1) having at least three shift positions, among which is a basic position. The actuating element (1) for selecting an operating state of the technical system, starting from its initial position, can be deflected at least in one direction into an intermediate shift position. For selecting at least one further operating state of the technical system is the Betagigungselement (1) starting from an intermediate shift position into at least one further than the intermediate shift position from the home position further switching position, deflected. The actuating device according to the invention is characterized in that the actuating element is a rotary switch (1) which automatically reset itself from all shift positions in the basic position. The actuating device comprises a locking arrangement against inadvertent deflection of the rotary switch (1) starting from an intermediate shift position into a further shift position. With the invention in particular the undesired switching of intermediate positions of an actuating element is effectively prevented. At the same time intuitively easy to understand tactile feedback of the switching state of the actuating element or the system state is realized with the invention. Furthermore, can the actuator, ...
