an insulative housing defining an opening for receiving a mating plug having a plurality of conductive terminals;

a plurality of electrical contacts disposed in said opening to slidably engage said conductive terminals of said mating plug, respectively;

wherein at least one of the electrical contacts has a conductive base and a low conductive material molding over a portion of the conductive base to form a conductive area and a less conductive area adjacent to said conductive area, when the plug is fully mated in the opening, the corresponding conductive terminal abutting the electrical contact on said conductive area, and when the plug is being withdrawn therefrom, the place where the electrical contact abuts the conductive terminal translates away from the conductive area to the less conductive area, and disengages the electrical contact therefrom;

wherein the conductive base is formed with a plurality of slots extending perpendicularly to the conductive area;

wherein the low conductive material encircles the conductive base and part of the low conductive material is disposed within the slots of said conductive base.
