摘要： The invention relates to a cut-out blade magnetic drive for electric switchgears, e.g. contactors. The aim is to overcome the tolerance problems associated with iron components and pre-assembling the device as a compact unit. To this end, a yoke (28), a magnet core (30), a pole plate (32) and a cut-out blade (68) are secured in a coil body by means of a clamping spring exerting a force so as to be self-adjusting and non-detachable. The coil body (34) has parts (76; 82; 83) exerting a counter-pressure against parts of the housing (12, 14) which correctly position the cut-out blade magnetic drive (16) in relation to its limits of travel (A; B) within the housing (12, 14).

摘要： The invention relates to a switch magnet control system for contactors (2). The contactor (2) has a coil (7) and a sensor (3) and the position of the armature (4) can be determined by the sensor (3). Different freewheeling circuits can be connected parallel to the coil (7) in relation to the position of the armature (4).
