A connector with a slot for receiving a smart card with contact pads, includes contacts that are held away from the card slot until the card becomes fully inserted, using a mechanism with a minimum number of easily formed parts. The mechanism includes a rocker (142) with a control part (144) that is pivotally mounted about a rocker axis (Y-Y) and that has a rear end forming a tab (186) that projects into the rear end of the card slot, to be deflected downwardly by the card reaching its fully inserted position. The control part also has a front end (174) that is coupled to the contacts to depress them until the card is fully inserted, whereupon the contacts are released to move up. The rocker, which is formed from a single piece of sheet metal, includes a pair of laterally-spaced fastening plates (150) that are fixed to the housing, and a pair of deflectable portions (148, 154) that can be resiliently deformed to permit the control part to pivot. The deflectable portions include torsion bars (148) that can be twisted about the rocker axis and that bias the control part towards the position where the rear end extends into the card slot. The front end of the control part is coupled to the contacts through a plastic molded lever (112) that is pivotally mounted about a second lateral axis (X-X) on the housing.
