ABSTRACT:
A control device, particularly a rotary controller for manual entry of information into an electronic device, has a setting member the position of which can be changed under the effect of an actuating force. The setting member is connected with a generator for producing electric signals which characterize the position of the setting member. A drive element is connected with the setting member and, under the control of the electric signals, exerts a force on the setting member which acts in the same direction as or in the direction opposite to the actuating force, depending on the position of the setting member for haptic acknowledgement of the operation of the setting member.
