摘要： A remotely-controllable electromagnetic switching apparatus including a housing, a contact bridge carrier disposed within the housing, and means for mechanically latching the contact bridge carrier by locking the contact bridge carrier in an operative switching position by means of a first lever member which is movable into a return-movement region of the contact bridge carrier by means of a spring force and is pivotably coupled to a second lever member. The improvement comprises the lever members comprising toggle levers which are movable into an almost fully-extended, beyond dead-center position for blocking return movement of the contact bridge carrier into the return movement region. At least one of the toggle levers is coupled to and guided by rollers which engage the housing of the switching apparatus.

摘要： An interlock mechanically locks out of one of two electromagnetic switching devices which are located side by side while the other switching device is in its closed position. The interlock achieves this lockout by adapting the moving parts of the switching devices, which are to be coupled, to locking elements. The locking elements are preferably slide bars which extend from the interlock. The moving parts of the switching devices form coupling members for auxiliary switches. These auxiliary switches can be set onto the switching device. The slide bars conform to the coupling members. This makes it possible to mount an interlock, for two electromagnetic switching devices located side by side, in place of or in addition to auxiliary switch units.

摘要： 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.
