  • Electrical contactor
    Patent number: 9136068
    Abstract: An electrical contactor has a first terminal having an electrically-conductive fixed member with fixed contacts on opposite faces thereof, and a second terminal having a terminal body and an odd-number of electrically-conductive movable arms extending from the terminal body. Each movable arm has a movable contact thereon remote from the terminal body. The movable arms are arranged to oppose each other such that their movable contacts are on either side of the fixed member and aligned with the fixed contacts. The arrangement of the fixed member and the movable arms is such that, when the contacts close, current flowing through the movable arms produces a force which urges the movable arms towards each other thereby increasing a force between the fixed and movable contacts. The number of movable arms at each side of the fixed member is different.
