ABSTRACT:
An actuator mechanism for imparting movement to a movable member includes a first lever pivoted about a pivot axis and engageable by the output member of an electromagnetic device after an initial movement thereof. A second lever is provided which is pivotable about a fulcrum and which is engaged with said output member so as to move about said fulcrum during the initial movement of the output member. Means is provided on the second lever which engages the first lever between the movable member and the point of engagement of the output member whereby the lever ratio between the output member and the movable member is high after said initial movement has taken place but is low while said initial movement is taking place.
