A socket for an electrical part comprises a socket body having a mount portion on which an electrical part having terminals is mounted, a number of contact pins to be contacted to or separated from the terminals of the electrical part and a movable plate disposed to the socket body to be movable perpendicularly with respect to the mount portion in a usable state of the socket. Each of the contact pins has a pair of elastic pieces formed, at front end portions thereof, with contact portions which are opened or closed in accordance with the movement of the movable plate thereby to establish an electrical connection between the contact portions and the terminals of the electrical part when the contact portions are closed. The movable plate is provided with cam portions arranged between adjacent contact pins, respectively, and when the movable plate is moved, the elastic pieces are pressed by a pair of cam portions disposed on both the sides of each of the contact pins thereby to open the contact portions.
