Abstract: An electromagnetic switching device comprises a housing containing a switch contact space and connection contact space, and a driving space formed by a basic body in which the magnet and coil are lodged. The parts of the connection contacts and coil connections of the pre-assembled contact carrier with return spring and of a switch space cover with an insertion device that can be releasably fastened to said cover, which are to be accommodated in the housing, are assembled in succession from a direction perpendicular to the sliding direction of the contact carrier and retained by interlocking connections.
