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.
