Abstract

The magnet system is part of a relay, which displays particularly low-noise switching. Components of the magnet system include a core unit (1), an armature (6) and a not represented coil, whereby the armature (6) is preloaded in an open position. The low-noise switching behavior is achieved in that the armature (6) is designed in such a manner that the armature pole face in the region of its front end (8a) in the closing direction is essentially perpendicular to a connecting line (16) towards the bearing edge (12). In addition, when the armature (6) is attracted, the core pole face (9) extends at least substantially parallel to the armature pole face (8). The arrangement according to the invention requires no additional parts for the purpose of noise reduction, resulting in a particularly simple and compact structure.
