Abstract

An electrical connector includes an electrically insulating body having a base mating surface and a stepped mating surface offset from the base mating surface. The electrical connector either has first and second electrically conducting pins extending from the base and stepped mating surfaces, respectively, or has first and second electrically conducting sockets extending from an interior portion of the electrically insulating body to the base and stepped mating surfaces, respectively.
