Abstract

An electrical connector (39) provides high density interconnections through contact paths of printed circuit pads (12, 31) via flexible circuit (22) having contact pads (26, 28) driven by a canted coil spring (40) formed of a shape memory alloy selectively responsive to variations in temperature applied to the coil through a medium, heated or cooled and supplied via passage (62) in the connector.
