[57] ABSTRACT
An electrical pin contact for mounting on a printed circuit board to provide an electrical interconnection to the printed circuit board. The contact includes an elongated, conductive pin, and a base attached to one end of the pin. The base has a triangular cross-section with vertices that engage a platethrough hole to support the contact in the plated-through hole during a soldering process. The contact may include a flange or stops to support the contact on a printed circuit board. The contact may also include a tail extending from the base opposite the pin.
