ABSTRACT:
An apparatus is disclosed for transmitting force from an actuating element of an electromagnet to a component to be actuated. The actuating element and the component to be actuated are substantially axially aligned. The lever is supported upon and rotates about a stop which is at a predetermined distance from both the push-pin axis and the axis of the component. When the point of contact of the lever with the push-pin is closer to the axis of the component than the point of contact of the lever with the component, the apparatus provides a mechanical advantage greater than 1. As a result, the component is moved with an enhanced force in the initial stages of its movement. In a preferred environment, several levers are arranged symmetrically about the axis of the component to be actuated to reduce cross-forces.
