ABSTRACT:
A current limiting contactor characterized by stationary and movable contacts, an elongated conductor supporting the movable contact, the conductor being fixedly mounted at a position spaced from the movable contact, the conductor having a looped portion including a pair of overlapping segments for conducting current in opposite directions of each other, the movable contact engaging the stationary contact when conducting a current up to a predetermined current value, and the conductor being comprised of a flexible material and the overlapping portions being separable to move the movable contact away from the stationary contact when the current exceeds said predetermined value.
