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).
