Abstract

An electrical contactor includes a moveable core member having a first moveable core surface and a second movable core surface. The second moveable core surface is angled relative to the first moveable core surface. A stationary core member is mounted relative to the moveable core member. The stationary core member includes a pole arm having a first stationary core surface and a second stationary core surface. The second stationary core surface is angled relative to the first stationary core surface. In response to a magnetic field traversing a path defined by the stationary core member and the moveable core member, the first stationary core surface is magnetically biased to mate with the first moveable core surface and the second stationary core surface is magnetically biased to mate with the second moveable core surface to bring into contact an electrical contact member and an electrical contact element.
