摘要： The invention relates to an electrical switching arrangement (1) comprising an armature (41), a solenoid assembly (3) which has a first bearing site (61) and in which the armature (41) is borne movably in a switching direction (S), and comprising an armature shaft (15) which is fixed to and moves together with the armature (41). To prevent a tilting and a resulting locking of the armature (41) or the armature shaft (15), but without reducing the shock resistance or requiring a costly bearing coating, it is envisaged according to the invention that the armature shaft (15) is borne at an additional bearing site (83) in the solenoid assembly (3).

摘要： A pair of colliding parts (14, 15) are formed on a mold frame (8) to face the back of a movable core (4) on the opposite sides of a movable contact support (6), and a step S is provided by setting the colliding part (14) higher than the colliding part (15). An inclining face (16) is formed on the side of the bottom face touching the back of the movable core of the movable contact support (6) closer to the colliding part (14). When the electromagnetic contactor is fixed while locating the higher colliding part (14) on the lower side, the movable contact support (6) colliding upon release is turned about the colliding part (14) as a fulcrum thus relaxing impact. When the electromagnetic contactor is fixed while locating the lower colliding part (15) on the lower side, the movable contact support (6) drawn to the movable core side by means of a leaf spring (5) collides against the back of the movable core through the inclining face (16) when the movable contact support (6) rebounds to cancel rebounding inertial thus relaxing impact.

摘要： The molded frame (8) is formed with a pair of collision sections (14 and 15) that are opposed to the back face of the movable iron core (4) with the movable contact support (6) there between. The collision section (14) has a higher height than that of the collision section (15) to provide the step S. An inclined plane (16) is also provided in the vicinity of the collision section (14) of the base bottom face abutted with the back face of the movable iron core of the movable contact support (6). When this electromagnetic contactor is attached with the higher collision section (14) provided at the lower side, the movable contact support (6) having collision in the "released" condition is rotated around the collision section (14), thereby reducing the impact. When this electromagnetic contactor is attached with the lower collision section (15) provided at the lower side on the other hand, the movable contact support (6) attracted toward the movable iron core by the plate spring (5) is allowed to collide, at the bounce of the movable contact support (6), with the back face of the movable iron core via the inclined plane (16), thereby canceling the inertia by the bounce to reduce the impact.

摘要： Control of an induction motor (89) is carried out to limit damaging arcing stress and mechanical stresses placed on the control contactor assembly (88) and the induction motor (89) resulting from the simultaneous or synchronous breaking and making of contactors (90A-90C) employed to connect the windings of the motor (89) to a power supply (92). Asynchronously connecting the windings (A-C) to the power supply (92) via the asynchronous or non-simultaneous closing of the contactors (90A-90C) of a modular contactor assembly (88) reduces the potentially damaging transient current, the associated torque oscillations, and mechanical stresses. The present invention is particularly applicable to delta motors (89) that are started with its windings (A-C) in a star or wye configuration followed by the reconnection of the windings (A-C) in a delta configuration when the motor (89) is at normal running speed.
