ABSTRACT:
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.
