Abstract
A contact structure for a circuit interrupter consists of a cylindrical cluster of spring wire members, each having a U shape with axially inwardly reentrantly bent tips at the base of the U shapes. Alternate members in the cylindrical cluster have their reentrant sections axially displaced from one another so that the tips of alternate members terminate in spaced first and second planes which are perpendicular to the axis of the cylindrical cluster. The two sets of wire members are interleaved, whereby the longer fingers straddle the legs of the shorter members, thereby defining two internal contact regions at the base of the two reentrant bent sections.
