摘要： The invention relates to a magnet system forming part of a relay characterized by especially low-noise switching. The magnet system comprises a core unit (1), an armature (6) and a coil which is not illustrated. The armature (6) is preloaded in an open position. Low-noise switching is achieved because the armature (6) is shaped in such a way that the front end of the armature pole face, as seen in the direction of closure, is substantially perpendicular to a connecting line (16) leading to the locating edge (12). Moreover, when the armature is attracted (6) the core pole face (9) is at least approximately parallel to the armature pole face (8). The system provided for in the invention requires no additional noise-reduction parts and thus has a very simple and compact structure.

摘要： The invention relates to a load-disconnecting switch with a permanent magnet holding circuit. When excited, a coil (5) generates a magnetic flux that is opposite to the flux of the permanent magnet (9). The armature (6) is pre-stressed in an opened position by an armature spring (10) so that the armature spring (10) detaches the armature (6) from the core (7) of the magnet system, opening said armature, when a defined excitation is exceeded, and thereby disconnecting a switch contact (15) from a stationary contact (16). The load-disconnecting switch can be switched on again by means of a spring clip (12) that acts on the armature (6).
