Abstract

Abstract A novel conductive contact comprises a dual beam spring (308, 310) which forms a "C" shaped spring and which is used to electrically mate to a contact on a printed circuit board. The open end of the "C" spring preferably fits over a plastic rib (404) in a housing for support. A surface mount contact (504) on the PCB has formed wings which fit into a rectangular slot in the PCB. To make electrical connection, the board is placed over the "C" spring. The "C" spring and plastic support protrude through the rectangular slot in the PCB. The conductive contact is preferably formed from a single piece of metal.
