Abstract: An embodiment of the present invention discloses an electromagnetic switching device including a housing including a mounting side and a connector side opposite the mounting side. The connector side includes one first and second main connection area for connecting first and second main lines to first and second fixed main contacts disposed in the interior of the housing. In the interior of the housing, movable main contact bridges are disposed via which one main current path each main current path includes one of the first fixed main contacts, one of the second fixed main contacts, and one of the main contact bridges. The main connection areas are located opposite one another. One first and one second central area are disposed between the main connection areas. The central areas each extend from the first to the second main connection area. The central areas are elevated relative to the main connection areas and disposed next to one another viewed from the first to the second main connection area.

Abstract: In one embodiment of the present invention, a production method for an electromagnetic switching device includes the following steps in the sequence listed: producing a one-piece switching chamber, producing a contact bridge carrier and equipping the contact bridge carrier with movable contact bridges, wherein the contact bridges include a plurality of primary contact bridges and at least one auxiliary contact bridge; inserting the contact bridge carrier equipped with the movable contact bridges into the switching chamber; inserting partition elements into the switching chamber so that each partition element is arranged between a bridge contact point of one of the primary contact bridges and a bridge contact point of one of the auxiliary contact bridges, and equipping the switching chamber with fixed primary counter-contact points; fixing primary covers to the switching chamber so that the primary covers cover the primary counter-contact points and fix the partition elements in the switching chamber.

Abstract: When manufacturing a starting device for a three-phase electric motor, especially a soft starter, in at least one embodiment an arc quenching system is at least partly removed from a commercially available contactor that so becomes to a modified contactor. In at least one embodiment, a modified contactor is used as a contactor in the starting device.

Abstract: A vacuum contactor includes a stationary contact and a moving contact, which can be moved in order to produce a current-carrying connection. In order to guide the moving contact during its movement in the enclosure, at least one guide element, which can be moved in a groove, is provided on the moving contact.
