Abstract
An electrical contactor includes a first stationary contact bar with first and second contact surfaces, and a single moving contact bar with first and second contact surfaces. The first and second contact surfaces of the first stationary contact bar and the first contact surface of the single moving contact bar are configured such that, when the single moving contact bar travels towards the first stationary contact bar, the first contact surface of the single moving contact bar touches the first contact surface of the first stationary contact bar in a first contact point, and the second contact surface of the first stationary contact bar in a second contact point. At least one of the first and second contact surfaces of the first stationary contact bar or the first contact surface of the single moving contact bar have a convex shape to establish the first and second contact points.
