  • Electromagnetic actuating device for a switching element
    Patent number: 11075042
    Abstract: An electromagnetic control mechanism for a switching element is described herein, which can be switched to an open operating state and to a closed operating state by means of an electromagnet and an actuating unit that acts counter to the actuation force of the electromagnet. The electromagnet has a dedicated mechanism for dampening the actuation movement of an anchor of the electromagnet toward a section of the coil, by means of which the actuation speed of the anchor can be reduced after a distance between a section of the anchor facing the coil and the section of the coil becomes shorter than a predefined distance.
