Abstract
A contact is for a vacuum interrupter. The contact includes a contact member having a generally planar mating surface with a planar contact plane and a plurality of purposely introduced undulations therein. The undulations are structured to contact a plurality of purposely introduced undulations of another contact member. The undulations are in a dimension perpendicular to the planar contact plane. The planar contact plane has a diameter. The undulations have a depth substantially smaller than the diameter of the planar contact plane.
