Abstract

An apparatus for depositing metal which provides a brushless electrical current continuity between a member, such as an electroforming mandrel or an electroplating rack, and a current source, comprising: (a) an electrode; (b) a member, spaced apart from the electrode, wherein the member defines a space that is partially or fully filled with a first conductive liquid in electrical contact with the member; (c) a second conductive liquid electrically isolated from the electrode; and (d) connecting means for electrically connecting the first conductive liquid and the second conductive liquid.
