Abstract
A solderless electrical contact commonly called a press-fit contact pin includes a press fit section comprising, in cross section, a double open curved or arcuate section generally resembling an 'S' shape and a longitudinal section having tapering cross-section to provide a lead-in angle. More particularly, the press-fit section has curved faces each formed from an arc of radius defined as ##EQU1## where R is the radius, S is the height of the rectangular blank, T is the thickness of the material disposed between said curved surfaces at their closest point, and L is the length of the press-fit section.
