<p>Electromagnetic Relay The invention relates to an electromagnetic relay in which the magnet yoke (18), with the aid of lateral projections (28, 29) is positionally fixed in cut out portions (26, 27) provided in the side walls of a housing member. When looked at in the longitudinal direction (25) two cut out portions (26, 27) are provided for behind each other, in each of which there is a supporting web (31, 32). The one of these cut out portions (26), together with the supporting web (31), serves as the swivel point for the magnetic system and the other one of the cut out portions (27), together with its supporting web (32) is positioned in such a way that the magnetic system is in such an installation position that, in the state of rest of the armature (19), the contacts (11, 12, 13, 14) are in the operative position. By deforming the cut out portion (27) owing to a bulging of the cover portion (5) and the supporting web (32), the magnetic system is pressed in the downward direction and, in the course of this, swivelled about the supporting point (33). Upon or after reaching the switchover point of the contacts (11, 12, 13, 14),the adjusted position is assumed and the further deformation is stopped. In this way it is possible to achieve a simple adjustment of the magnetic system (15) relative to the contact system (8). (Fig.1)</p> |
