ABSTRACT OF THE DISCLOSURE Press-fit pins for insertion into plated-through holes in printed circuit boards are disclosed. A pin embodying the invention has a compliant contact section comprising a pair of longitudinally extending beams whose cross sections are in the form of opposed C's. The radius of curvature of each of these C- sections is greater than that of the hole into which the pin is to be inserted and the ends of the arms of the C's fit a circle having a larger diameter than that of the hole. Accordingly, when the pin is inserted into the hole, the ends of the two arms of each C are forced toward each other. Also the compliant sections bend so that the C's are forced toward each other. With this arrangement the contact section has six circumferentially spaced areas of contact with the conductive surface of the hole. Moreover, the pin can be removed and replaced by a pin of the same size, while retaining the desired reliability of electrical contact.
