ABSTRACT:
A sealed contact includes a capsule enclosing a pair of magnetic reeds. Each reed has a fixed end sealed in the capsule and a flat movable portion with side edges substantially parallel to one another for a predetermined length and tapered toward one another from the end of the predetermined length to the tip of the movable portion. The reeds are positioned so that the movable portions overlap one another by an overlap length and define an overlap area which is less sensitive to variation in overlap length than a conventional sealed contact having reeds cut substantially normal to the parallel side edges.
