Abstract (en)
[origin: US4988964A] In an electromagnetic switchgear with movable contact parts held in a movable contact support and forming, with fixed contact parts, opening and closing contacts, the contact support being elastically connected with the armature in such a way that, with the opening contact welded, an onward movement of the movable magnet part is possible without operation of the closing contact, the yoke of the magnet system is also suspended elastically in its closing direction and this elastic suspension, the elastic connection between the armature and contact support and the elasticity of the movable contact parts are matched to one another in such a way that with the opening contact welded and the magnet system closed, the spring excursions of the armature and yoke are approximately the same.
