CONTACT MEMBER INCLUDING PURPOSELY INTRODUCED UNDULATIONS AND VACUUM INTERRUPTER INCLUDING THE SAME

摘要

A contact (20) is for a vacuum interrupter (110). The contact )20) includes a contact member (24) having a generally planar mating surface (28) with a planar contact plane (32) and a plurality of purposely introduced undulations (36) therein. The undulations (36) are structured 5 to contact a plurality of purposely introduced undulations (38) of another contact member (26). The undulations (38) are in a dimension perpendicular to the planar contact plane. The planar contact plane has a diameter (40). The undulations (38) have a depth substantially smaller than the diameter of the planar contact plane.
