Abstract: Device for pivoting a motor-vehicle mirror in or at a car from the normal position (fully-reflecting condition V) to a non-dazzle position (partly-reflecting condition T) in the event of excessive glare (B) from the headlight of a following vehicle and taking into account any interference from ambient light (U), said device comprising a voltage-source, a motor (M), the shaft (10) of which acts upon the mirror through a tilting mechanism and which is fed from thyristors (T1 and T2) which are, in turn, controlled by transistors (TR1, TR2 and TR3) with the aid of photodiodes or photoresistors (B, U) for glare and interference from ambient light. A bipolar rotary switch (DS) is connected in series with the motor (M), said switch interrupting the flow of current through the motor in accordance with a specific angle of rotation of the shaft thereof, disconnecting the previously conducting thyristor (T1 or T2) from the voltage-source and switching it off.
