Abstract: A contactor includes a housing having a mounting side, an operating side, main connector surfaces and side surfaces. The operating side lies opposite the mounting side and is connected to the mounting side by main connector surfaces and side surfaces. The main connector surfaces lie opposite one another and the side surfaces lie opposite one another. The operating side has a raised central area and two edge areas, which border a central area on both sides of the central area. The edge areas border the main connector areas and are connected to the central area by way of an additional connector area in each case. Main terminals, connected to load contacts of the contactor, have main receptacle openings into which main conductors are fed from one of the main connector surfaces. Additional terminals have receptacle openings into which additional conductors are fed from additional connector surfaces.

Abstract: A contactor is disclosed, including a housing, which has a mounting side, an operating side, two main connector surfaces and two side surfaces. In at least one embodiment, the operating side lies opposite the mounting side and is connected to the mounting side by way of the main connector surfaces and the side surfaces, wherein the main connector surfaces lie opposite one another and the side surfaces lie opposite one another. The operating side has a raised central area and two edge areas, which border the central area on both sides of the central area, wherein the edge areas border the main connector areas and are connected to the central area by way of an additional connector area in each case. Main terminals, which are connected to load contacts of the contactor, have main receptacle openings into which main conductors can be fed from one of the main connector surfaces in each case.

Abstract: The invention relates to an electromagnetic switching device, in particular a contactor, comprising a switching device housing (2) and a plug-in module which can be inserted into the latter and which contains a coil form (12) for a coil. A tripping element (60) is mounted on a housing section (40) of the plug-in module (4). Said element is designed to mechanically actuate the contact unit (30) of an electric switch (24) for producing an economy connection. The switch (24) is mounted on a support structure (printed-circuit board (22)) that is located in the plug-in module (4), with a supporting contour (70) of said switch adjoining a bearing contour (72) of the housing section (40).

Abstract: An electromagnetic switching device, especially a contactor, includes a base, an arc chamber removable from the base, a contact bridge support and a spring-loaded locking element. The contact bridge support projects into the arc chamber and can be displaced in a direction of actuation. The contact bridge support can be locked by the locking element when the arc chamber is taken off. The locking element is configured as a lever that is swiveled about a swiveling axis which extends in perpendicular to the direction of actuation.

Abstract: An electromagnetic switching device includes a housing and a plug-in module which can be inserted into the housing at an insertion point in a direction of insertion. The plug-in module holds a magnetic yoke, attached to which is a coil unit. Two extensions, which point respectively to the front and to the rear in relation to the direction of insertion, are formed on the magnetic yoke. In order to retain the magnetic yoke, a retaining bracket extending transversally in relation to the direction of insertion, overlaps one of the fixing extensions and engages two retaining tongues from below, said tongues being formed as one-piece with the plug-in module.

Abstract: The invention relates to an electromagnetic switching device, especially a contactor, comprising a base (1), an arc chamber (2) removable from the base (1), a contact bridge support (4) and a spring-loaded locking element (5). The contact bridge support (4) projects into the arc chamber (2) and can be displaced in a direction of actuation (x). The contact bridge support can be locked by means of the locking element (5) when the arc chamber (2) is taken off. The locking element (5) is configured as a lever that is swiveled about a swiveling axis (10) which extends in perpendicular to the direction of actuation (x).

Abstract: A connecting element is provided which has integrated catches in the area of the engagement sections, so that after they are inserted into engagement grooves have a matching shape on the individual contactors, the catches are engaged on a housing contour. Due to this design, when the individual contactor is screwed onto a base plate, dislocation of the connecting elements and migration to the base plate is prevented.
