A compliant pin has an intermediate portion formed with end sections relatively slidable with a central section. The end sections have outside edges with a small curved portion separated from a longer curved portion further from the central section by a straight portion, the radius of curvature being of the order of the radius of a plated-through hole in which the intermediate portion is to be seated. The central and end sections are always in overlapping relationship along inside edges for a length less than half the length of each inside edge.
