A control system having a rotatable knob for selecting various operating modes is described. The control system includes a stationary toroidal coil and a braking washer operatively connected with it. The rotary direction, the angular deflection and the function of the braking washer are scanned and supplied to an electronic processing system, whereupon the processing system furnishes the actual control commands to the equipment to be controlled. Among the uses for the control system are to enable remote control of various kinds of equipment in at least two modes of operation, one of them being speed control as a function of the rotational speed of the control system.

Control system for controlling the operating mode of an apparatus (M) having a movable operator controllable knob (1, 50), said knob being deflectable from a reference position by being rotatable and axially shiftable, for controlling operating modes of the controlled apparatus (M, 28) by rotation and axial shifting of the knob, including means (23, 24, 36) for scanning deflection of the knob from the reference position and providing knob movement signals representative of said deflection, said knob movement signals including a first electrical control signal representative of the angular deflection of the knob and a second electrical control signal representative of the speed of angular deflection, and of the direction from the reference position of the knob, said system comprising a toroidal coil (7, 64) positioned concentrically with the axis of rotation (5) of the operator controllable knob (1, 50); a brake disk (2, 63) magnetically coupled to the toroidal coil and further mechanically coupled to the knob for effecting braking at a predetermined angular deflection of the knob; and control means receiving said knob movement signals coupled to and selectively energizing said toroidal coil.
