An electrical connector (100) for electrically mating with two different mating interfaces includes an insulative housing (1) defining a first and a second mating spaces (114, 124) located at opposite ends, a plurality of contact terminals (2) received in the insulative housing (1) each of which integrally defines an upper beam (2a), a lower beam (2b), and a fulcrum portion (21) connecting the beams at middle thereof, an actuator (4) pivotally assembled on the housing (1) and capable of rotating between an opened position in which one of the mating spaces (124) is accessible, and a closed position in which the actuator (4) is substantially covering said mating space (124). Each contact terminal (2) forms a first contact portion (221, 231) extending toward a first mating space (114) from the fulcrum portion (21), a second contact portion (251) extending toward a second mating space (124) from the fulcrum portion (21), and a soldered portion (252) solderable onto a PCB (400) which the electrical connector (100) located thereon or therein.
