1. An apparatus for use with an electrical plug having contact holes for electrical contact pins, the apparatus comprising:
a housing configured to receive the plug, a portion of the housing having a circular periphery with alignment protrusions;
a circuit block configured to mate with the housing within the circular periphery of the housing, the circuit block having a polygonal periphery with alignment indentations configured to receive the alignment protrusions on the housing for the circuit block to mate with the housing in only one orientation; and
electrical contact pins projecting from the circuit block to enter the contact holes when the plug is inserted in the housing;
wherein the alignment indentations on the circuit block interrupt the polygonal periphery at each linear side of the circuit block;
wherein the polygon periphery of the circuit block is rectangular with four alignment indentations;
wherein the four alignment indentations are located at the four corners of the rectangle; and
wherein the four alignment indentations include diagonally opposed indentations that are configured differently from each other.
