ABSTRACT:
A printed circuit contact of the type for attachment to a control device such as a rotary switch and a method for forming the printed circuit contact, the printed circuit contact comprising an elongated rigid tail resistant to bending and an integrally connected spring clip comprised of a pair of resilient jaws, the jaws being formed from material having a thickness less than the thickness of the tail and wherein the jaws and the tail are formed from a single piece of material. The method of forming the printed circuit contact includes milling a longitudinal groove in one surface of a strip of sheet stock so that a portion of the sheet stock is substantially thinner than the remainder. The sheet stock is then stamped and subjected to bending operations such that the thinner milled portion of the sheet stock is employed to form the jaws of the clip and the thicker portion of the stock forms the tail.
