    • A spring guide is provided for a carrier assembly of an electrical switching apparatus such as, for example, a circuit breaker. The carrier assembly includes a carrier body, a plurality of movable contact arms (104) pivotably coupled to the carrier body, and a plurality of contact springs (108). Each of the contact springs is disposed between a portion of the carrier body and a corresponding number of the movable contact arms. Each spring guide includes a guide member (112) disposed between a corresponding one of the contact springs and the corresponding number of movable contact arms to maintains alignment therebetween. The guide member preferably includes a planar portion (116) including a first side, which spans a pair of adjacent movable contact arms, and a second side, which includes a projection (124). The projection is disposed within the coils of the corresponding one of the contact springs.
    • 为电气开关装置(例如断路器)的承载组件提供弹簧引导件。 载体组件包括载体主体,可枢转地联接到载体主体的多个可动接触臂(104)和多个接触弹簧(108)。 每个接触弹簧设置在载体主体的一部分和相应数量的可动接触臂之间。 每个弹簧引导件包括设置在对应的一个接触弹簧和相应数量的可动接触臂之间的引导构件(112),以保持它们之间的对准。 引导构件优选地包括平面部分(116),该平面部分包括跨越一对相邻的可动接触臂的第一侧和包括突起(124)的第二侧。 突起设置在对应的一个接触弹簧的线圈内。
