Abstract
The electrical control system for an electrically powered foldable rearview mirror having a mirror body mounted on a hollow supporting shaft extending from a supporting base so as to be movable between a folded state and an erected state, comprises a reversible motor and reduction gear drive contained in the mirror body; a motor drive circuit connected to the reversible motor to drive the mirror body between the folded state and the errected state; a mechanical stop device to stop rotation of the mirror body when the mirror body reaches the erected state or the folded state including convex and concave portions on the a root portion of the shaft and mirror body respectively; a noncontacting sensor for detecting a halt to motor rotation as a result of a halt of mirror body rotation; and a control circuit for interrruption of the motor drive circuit when the noncontacting sensor detects the halt of the motor rotation.
