<p>The control mechanism is designed for control of an automatic system. The mechanism has movable element fixed to a system to be controlled. The element has a face perpendicular to its displacement direction. The mechanism has a cam which rotates around an axis parallel to the surface. The cam has a plane face as well as a operating arm. The mechanism permits, in its rest position, the automatic operation of the system. The mechanism has a hand operated element (11) fitted with a control button (13). The element (13) has a fork (12) whose arms (12a, 12b) inclined. Arm (12a) is inclined with respect to (12b) which has a vertical face. The exterior of the arm (12a) has an inclined part followed by a horizontal part which forms a slide track. A cam (6), has a lever (7) fitted with a pin (15). The pin (15) engages in the arms (12a, 12b) of the form (12). The cam (6) pivots around an axis (8) and can be pulled back to the rest position by a spring (9). The cam (6) controls the movement of a magnetic circuit (1, 2, 3).</p> |
