Abstract
Abstract A HERMAPHRODITIC MULTI-CONTACT REED SWITCH INCLUDES A TUBULAR ENVELOPE HAVING A PAIR OF SUBSTANTIALLY IDENTICAL HEADERS SEALED INTO THE OPPOSITE ENDS AND CONTAINS AN INERT ATMOSPHERE. EACH OF THE HEADERS INCLUDES A PLURALITY OF SWITCH MEMBERS HAVING A MAGNETIZABLE PORTION EXTENDING INTERIORLY OF THE ENVELOPE AND IN LONGITUDINALLY OVERLAPPING RELATIONSHIP WITH THE MAGNETIZABLE PORTION OF THE SWITCH MEMBERS OF THE OPPOSITE HEADER. THE LONGITUDINAL OVERLAPPING MAGNETIZABLE PORTIONS OF THE MATCHING SWITCH MEMBERS OF THE OPPOSING HEADERS HAVE A DESIRED GAP THEREBETWEEN WHICH IS DEPENDENT UPON THE CIRCUMFERENTIAL DISPLACEMENT OF ONE HEADER WITH RESPECT TO THE OTHER.
