Patent ID: 7445190

Claim:
A mirror adjustment mechanism for adjusting a mirror housing of a motor vehicle, comprising: an actuator housing and a drive mechanism arranged in the actuator housing, the drive mechanism including: an electric motor including an output shaft; a drive train having an input part coupled to the output shaft and an output part coupled to a driven part, the driven part being configured to be integrated with said mirror housing such that the output part of the drive train is configured to provide pivotal movement of said mirror housing; and a driving part connected to an electrical circuit, the driving part is configured to be movable under a spring action relative to the actuator housing; wherein the driving part controls the electric motor and includes at least a first contact part that cooperates with at least a second contact part that is fixedly arranged relative to the actuator housing and is connected to the electrical circuit, and further wherein the driving part is movable between a first position in which the impedance between the first and second contact parts has a first value, and a second position in which the impedance between the first and second contact parts has a second value; the impedance between the electrical circuit and the first contact part varies during movement of the driving part; and the mechanism is configured so that through variation of the electrical impedance, the electric motor is switched off without performing additional switching operations.
