<p>A method for closely controlling the tolerances involved in the manufacture of a contact assembly is accomplished by a predeterminately positioned oblong hole in one corner of both the base plate and cover, and a predeterminately positioned circular hole in another corner of both the base plate and cover. Placement of the base plate and cover upon respectively positioned circular and oblong pegs allows the contact members of both the cover and base plate to exactly align. Welding of the base plate and cover is thereby accomplished within very close tolerances. The holes remaining in the finished contact are useful for aligning and mounting the contact during later operation.</p> |
