  • Motor starter
    Patent number: 7898373
    Abstract: A motor starter whose production is improved is specified. In at least one embodiment, the motor starter includes a power semiconductor switch, an electromechanical bypass switch connected in parallel therewith, and control electronics to drive the bypass switch. In at least one embodiment, the control electronics are in the form of a printed circuit board assembly which is fixed to the bypass switch in an installed position, and the printed circuit board assembly and the bypass switch are designed such that, when being fixed, the printed board assembly makes electrical contact with the bypass switch at the same time.
    Type: Grant

    Assignee: Siemens Aktiengesellschaft
    Inventors: Jürgen Trottmann, Johann Seitz, Markus Meier
  • Electromechanical switching device
    Patent number: 7737811
    Abstract: An electromechanical switching device of at least one embodiment includes fixed contacts securely arranged in a housing and a moving contact bridge for bridging the fixed contacts, a moving contact carrier to carry the contact bridge, and a solenoid to act on the contact carrier. In at least one embodiment the solenoid includes a coil body fixed to the housing, an armature coupled to the contact carrier so as to move with it, a yoke to act together with the armature, and a fixing mechanism, which engages with the yoke and coil body for fixing the yoke to the coil body.
