A contact, adapted for electrically connecting IC package and a printed circuit board, comprises a base, an upper spring arm and a lower spring arm. The upper spring arm is formed with an upper waist portion extending from a top edge of the base and a top end for electrically contacting with the IC package; and the lower spring arm is formed with a lower waist portion extending from a bottom edge of the base and a bottom end for electrically contacting with the printed circuit board. The bottom end has a width larger than that of the top end, and the lower waist portion has a width larger than that of the upper waist and defines a slot in a middle thereof.
