The present disclosure relates to an operating assembly consisting of a carrier, an actuating element that is mounted movably relative to the carrier and so as to return into a rest position and which defines an input surface and has a detector for detecting a touch occurring on the input surface, and of at least one rotary adjuster, which is disposed on the input surface and is mounted rotatably relative to the input surface, and of a matrix of force sensors between the carrier and the actuating element, and of an evaluator, which is configured for carrying out a positional determination of a touch that has occurred on the input surface from the signal obtained by the detector, and for identifying at least one action of the actuating force on the rotary adjuster based on the signals of the matrix of force sensors by a comparison with predetermined values.
