ABSTRACT:
A magnetically coupled communications port includes a switch for providing an enable signal upon coupling of a detachable magnetic coupler assembly to a fixed coupler assembly. The switch is magnetically activated and is positioned on the fixed coupler assembly in proximity to one end of a cylindrical slug of a magnetically conductive material. The opposite end of the cylindrical slug is positioned co-planar with an external face portion of the fixed coupler assembly. When the detachable magnetic coupler assembly mates with the fixed coupler assembly, contacting the face portion and the co-planar surface of the cylindrical slug, magnetic flux from the detachable magnetic coupler is concentrated through the slug causing the magnetically activated switch to switch from an inactivated position to an activated position.
