A socket (2, 52) for attachment to a printed substrate (10, 60), has a central aperture therethrough. A connective part (3, 53) including a flexible insulative sheet (8, 58) is provided to cover the aperture and act as an electrically connective interface between an electrical part (31, 81) mounted in the socket and the printed substrate. The flexible sheet (8, 58) has a first contact means (5, 55) associated with a first surface of the flexible sheet for electrically connecting with leads (32, 82) of the electrical part and a second contact means (6, 56) associated with a second surface of the flexible sheet for electrically connecting with the printed substrate. An electroconductive member (7, 57) provides electrical connection between the first and second contact means. Such a socket is especially useful for testing electrical parts with high clock speeds and a large number of leads.
