1. A control element has a control panel on a front side and a rear surface on a rear side of the control element situated opposite the front side, the control element comprises:
a vibration actuator operatively connected to a locally limited portion of the control panel so that a touch detected by a sensor on the locally limited portion of the control panel triggers a vibration of the vibration actuator;
the vibration actuator is connected indirectly, via a lever element, to the rear surface on the rear side of the control element, the lever element transmits a vibration of the vibration actuator to the rear surface of the control element in the area of the locally limited portion of the front side of the control panel;
the lever element includes a contact portion that rests against the rear side of the control panel in the locally limited portion of the control panel and the lever element has a geometric dimension that corresponds to the locally limited portion of the control panel;
the lever element includes a holding portion where the vibration actuator is held on the lever element, the holding portion of the lever element is arranged to swing freely relative to the rear surface of the control element.
