<p>The pusher is mounted in a case, and a permanent magnet system serves as a magnetic energy store interacting with a snap-action element with two stops. They interact with two suitably spaced stops on the operating pusher. An elastic support is provided between the case and the pusher, and a spring between the pusher and the snap-action element. The snap-action element (6) is designed as a bridge contact support. The permanent magnet system (12, 14, 16) is in the bridge contact(s) area and interacts with the snap-action element (6). The latter has a projection (6a, 6b) entering in a pusher (4) recess (4a). It forms a stop for the snap-action element (6), which the front side of the latter (6), at which the projection (6a, 6b) beings, forms the other stop interacting with the pusher (4).</p> |
