First Claim
1. A control system for a foldable outside rearview mirror, comprising an electric motor having an electric motor circuit;
- an operation switch;
trigger means connected with said operation switch for outputting a trigger pulse in response to actuation of said operation switch;
timer means connected with said trigger means for outputting a pulse of a predetermined pulse width to drive said electric motor only for a set time upon receipt of the trigger pulse from said trigger means;
polarity changing means having a pair of outputs of high and low level and formed for reversely switching said electric motor by inverting said pair of said outputs upon receipt of the trigger pulse from said trigger means; and
