ABSTRACT:
A control device for adjustment of reversible electrical adjusting devices, in particular of motor vehicle rear-view mirrors, having a selector switch which can be switched by means of a knob between a multiplicity of stable switching positions for selection of a mirror to be adjusted, and three tip switches, which can be switched by the same knob for the actual control of the adjusting device. A four-digit binary code, composed of signals of the selector switch and of the tip switches, is generated at four connection terminals of the switch arrangement by actuating the knob while maintaining the set position of the selector switch. In a fourth stable switching position of the selector switch, the switching contact of the said selector switch is not in contact with any of the fixed contacts assigned to it and the downstream connection terminals are potential-free. The fourth switching position of the selector switch can be used for the activation of further functions, preferably both outside rear-view mirrors of the vehicle can thereby be retracted and deployed under remote control, and a memory circuit can be made to store mirror positions manually/electrically set beforehand.
