ABSTRACT:
A pivotal mirror adapted for use in automobiles as a rear view reflector or in medical and dental establishments and the like. Actuation of the mirror is effected by a light sensitive element employed to energize electromagnets disposed on the back face of the mirror itself as well as on a critically located portion of its stationary housing, the moving and stationary magnets serving conjointly to pivot the mirror, for example, the rear view mirror of an automobile, in order to reduce the intensity of light in the driver's eyes emanating from a following automobile. The light sensitive element extends through the pivotal mirror not being displaceable therewith whereby it is always positioned to detect any change in the incident rays falling thereon.
