A reversible plug for coupling with a USB A-type standard receptacle includes a plug body with a set of four electrical contacts on each of two major surfaces. The plug body has regions of electrically insulating material interposed between, and extending above a level of, the electrical contacts on each major surface so that, when the reversible plug is inserted into the standard receptacle in either orientation, the regions of electrically insulating material prevent contact between the electrical contacts not in use and the electrically conducting shield.
