ABSTRACT:
An IC socket, capable of being applied to an IC device having short lead pins and ensuring reliable contact with the lead pins used, comprises contacts each having a first contact element that is substantially fixed and a second contact element that is elastically deformable, and an actuator for moving the second contact elements of the contacts. The second contact elements have their centers formed as engaging means for engaging with the actuator, and their portions near the surface of a socket body are formed as contacting means to be brought into contact with lead pins of an IC device. The second contact elements are located close to the first contact elements. When an IC device is inserted, the actuator separates the second contact elements from the first contact elements.
