Abstract
A sealed relay of the high-vacuum type, or which may be backfilled with a dielectric gas such as hydrogen-nitrogen mixture for improved arc suppression when switching high-voltage d-c currents. The relay uses controlled fixed contacts which enable use of a reduced-diameter disk-shaped movable contact. Thus permitting optimal placement of external arc-supporting permanent magnets on a ceramic relay housing in close proximity to the enclosed fixed and movable contacts. A staggered or offset positioning of the fixed contacts makes the relay polarity insensitive for bidirectional switching of high-voltage d-c currents.
