Abstract
An operating device with haptic response for the manual entering of information into a device comprises a setting member having a position which is variable under the action of an actuating force, and with which there is connected a transducer for producing electric signals which characterize the position of the setting member. There is connected with the setting member a braking element which, under control by the electric signals, exerts a force on the setting member, the value of which force depends on the position of the setting member. The braking element has at least two surfaces which are movable relative to each other and between which there is provided a force transmitting fluid the transmission properties of which can be varied by the electric signals.
