    Abstract: A magnet linear actuator includes a first element and an armature situated on a support, with the armature being movable along a movement axis between a first position engaged with the first element and the second position spaced away from the first element along the movement axis. The actuator further includes a biasing element that biases the armature in a direction generally toward the second position. The first element or the armature is pivotable with respect to the other between a first orientation and a second orientation. In the first orientation, the first element and the armature have a first magnetic attraction to one another that is sufficient to overcome the bias of the biasing element and to retain the armature in the first position. In the second orientation, the first element and the armature have either a magnetic repulsion to one another or a weaker second magnetic attraction.

    Abstract: An electrical switching apparatus includes two arc runners, two contacts in electrical communication with the respective runners, a movable contact having two portions respectively cooperating with the contacts to provide closed and open contact positions, and two arc chambers each including two ends, a longitudinal axis therebetween, and arc plates between the ends. A magnet assembly cooperates with the arc chambers to establish a generally unidirectional magnetic field normal to the axes, normal to a first direction of a first arc between one contact and the first portion as it moves away from the closed toward the open contact position, and normal to an opposite second direction of a second arc between the other contact and the second portion as it moves away from the closed toward the open contact position. The magnetic field causes one arc to enter one arc chamber depending upon current flow direction between the contacts.

    Abstract translation: 一种电气开关装置包括两个电弧流道,两个与各个流道电气连通的触点,一个可动触点,其两个部分分别与触头配合以提供闭合和开放的触点位置;以及两个电弧室,每个包括两个端部,纵向轴线 和它们之间的弧形板。 磁体组件与电弧室协同工作,以在垂直于一个接触件与第一部件之间的第一弧的第一方向垂直于轴线建立一个大体上单向的磁场,当它从闭合件朝向打开的接触位置移动时,以及 在另一触点与第二部分之间的第二弧的相反的第二方向上,当其从关闭状态朝向打开的接触位置移动时,该第二方向垂直于第二方向。 根据电流之间的电流方向,磁场使一个电弧进入一个电弧室。
