Electromagnetic relay and method for manufacturing such relay

An electromagnetic relay comprising a coil body, a tongue-shaped armature mounted in an axially through opening of said coil body, said armature having a fastening end secured in the region of a first coil flange to said coil body and having its free end switchable between two pole plates in the region of a second coil flange of said coil body, a flux transfer plate mounted against said first coil flange at the fastening end of said armature, whereby said pole plates have at least one section lying flat against the end face of said second coil flange and rest against two spacing members of said coil flange which are formed as extensions of the narrow sides of said armature, a respective sealing film at the end faces of both said first and second coil flanges, a rim bead (17, 47) formed on said first coil flange (4, 34) which surrounds the coil body opening (3, 33), said rim bead penetrated by two retaining webs (21, 51) of the armature (6, 36) which correspond to the height of the bead (17, 47) which penetrate at only two opposite sides thereof, the spacing members (23, 53) of said second coil flange (5, 35) project over the end face of said second coil flange (5, 35) with a height corresponding to the thickness of said pole plates (8, 8', 38, 38'), and said pole plates (8, 8', 38, 38') positioned between said spacing members (23, 53) and at retaining tabs (24, 54) provided at the edge of said coil flange (5, 35).
