Abstract
At least one electrical contactor is provided that includes a fixed contact and a movable contact. The fixed contact includes a center leg and first and second arms that extend in opposite directions from the center leg. The movable contact associated with each fixed contact includes first and second blades positioned on opposite sides of the center leg. The first and second blades extend parallel to the center leg of the fixed contact such that when current flows through the electrical contactor, the current flow creates a force to push the first and second blades into the first and second arms of the fixed contact. The electrical contactor includes an actuating arrangement having a pair of cam members. The movement of the cam members causes pegs on each of the first and second blades to travel within the cam channel, thus opening and closing the contactor arrangement.
