ELECTRICAL CONTACT SETS

摘要

An electrical contactor has a first terminal having a first fixed contact; a second terminal having a second fixed contact; a first electrically-conductive movable arm in electrical communication with the first terminal and having a first movable contact thereon; a second electrically-conductive movable arm in electrical communication with the second terminal and having a second movable contact thereon, counter-opposed to the first moveable arm; and an actuator for moving the first and second moveable arms in opposing directions. The first moveable contact and the second fixed contact form a primary contact set, and the second moveable contact and the first fixed contact form a secondary contact set, first and second moveable arms thereby forming a current-sharing arm pair between first and second terminals.

主权项

1. An electrical contactor comprising:
a first terminal having at least one first fixed electrical contact; a second terminal having at least one second fixed electrical contact; a first electrically-conductive movable arm in electrical communication with the first terminal and having at least one first movable electrical contact thereon; a second electrically-conductive movable arm in electrical communication with the second terminal and having at least one second movable electrical contact thereon, counter-opposed to the first electrically-conductive moveable arm; and an actuator for providing motive force to the first and second electrically-conductive moveable arms in opposing directions; wherein the or each first moveable electrical contact and the or each second fixed contact form a primary contact set, and the or each second moveable electrical contact and the or each first fixed contact form a secondary contact set, counter-opposed first and second moveable arms thereby forming a current-sharing arm pair between first and second terminals.
