Patent number: 10326349Abstract: 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.Type: GrantFiled: October 31, 2017Date of Patent: June 18, 2019Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Anthony T.

Patent number: 8853586Abstract: 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.Type: GrantFiled: October 31, 2012Date of Patent: October 7, 2014Assignee: Eaton CorporationInventors: Peter J. Theisen, Paul J. Rollman, Mark A. Juds, Xin Zhou
