Abstract: A card reader (2) especially for use in connecting gold plated pads on a subscribers identity module card (4) to respective tin plated pads on a printed circuit board (6) in a car telephone handset, comprises an insulating frame (8) having spigots (26) for fixing it to the circuit board 96), and a metal cover (12). A bar (22) spanning the frame (8) supports contact elements (10) molded thereinto. Each contact element (10) has a 10 contact spring (40) provided with a bowed, gold plated contact surface (5) near its free end for engaging a respective gold plated pad on the card (4), and intermediate its ends, an oppositely bowed, tin plated, contact surface (44) for engaging a respective tin plated pad on the circuit board 96). With the card (4) resting on a ledge (18) in the frame (8), the metal cover (12) is latched to the frame (8) to force the contact surfaces (44 and 50) against their respective pads.
