<p>An actuating system comprises a mobile part (return plate 7) held on a casing (1) by a return spring (17). In the rest state a precisely-determined magnetic discontinuity (19) is formed between the movable part and a stationary part (magnet core 3). The mobile part is connected to the return spring (17) by means of a force fit. The magnetic discontinuity (19) can be varied by pressing in more or less deeply a suitable connection, for example a pin (8), in the mobile part (return plate 7).</p> |
