Abstract
A vacuum interrupter having a continuous current rating of several thousand amperes comprises a pair of disc-shaped contacts primarily of beryllium that are respectively mounted on the inner ends of a pair of conductive contact rods. The mounting means for each contact comprises a backing member of truncated, generally-conical form that comprises: (i) a base of a predetermined diameter attached to the inner end of the associated contact rod and (ii) an opposite end of a relatively small diameter compared to that of said base attached to the disc-shaped contact. Each disc-shaped contact projects radially outward past the outer periphery of said opposite end of the associated backing member.
