Abstract

An activation device for selecting shift stages of a shift-by-wire vehicle transmission comprises a housing and an activation knob which can be moved in a translatory fashion and a latching device with a latching pin and latching contour as latching elements for generating latching forces and restoring forces. The activation device is defined by a latching gearwheel which is in engagement with a toothing arrangement on the activation knob. In this context, one of the two latching elements is connected to the latching gearwheel and in this way forms a rotatable latching element. The second latching element is directly or indirectly connected to the base housing and forms the fixed latching element.
