1. An apparatus for use in an automotive vehicle, said apparatus comprising:

  • a rotatable driving member;

    a driven member acting as a window wiper shaft;

    an actuator member driven by said rotatable member; and

    an automotive window, said window wiper shaft attaching to said automotive window and said window wiper shaft operably disengaging from said actuator member, thereby allowing said window wiper shaft to move with said automotive window;

    a magnetic coupling mechanism selectively coupling said driven member to said actuator member, a first portion of said magnetic coupling mechanism coupled to said driven member;

    said magnetic coupling mechanism including at least one of said actuator member and said driven member, said magnetic coupling mechanism having a magnetically conductive segment; and

    at least one of said actuator member and driven member having a solenoid segment adjacent to said magnetically conductive segment, whereby said actuator member magnetically engages said driven member when an electric signal energizes said solenoid segment;

    said driven member only being couplable to said actuator member by only magnetic force.
