Abstract
An electrical contact pin has a mounting portion to be fitted into a PTH of a circuit board for fixing without using any solder. The mounting portion has a substantially rectangular cross section. A pair of alternating recesses are provided on opposite sides of said rectangular section. A pair of corners adjacent to said recesses extend beyond said sides to form a pair of resilient projected sharp corners. Because of the resilient projected sharp corners, the contact pin fits into a PTH of large tolerances.
