An electrical contact includes a female portion having a conductive sheath, a dielectric disposed within the conductive sheath, and a center conductor extending through the dielectric; and a male portion having a conductive sheath, a dielectric disclosed within the conductive sheath, and a center conductor extending through the dielectric. The female portion and the male portion are arranged to be engageable with one another. The conductive sheath, center conductor, and dielectric of each of the female portion and the male portion have a substantially square shape. Each of the center conductors of the female portion and the male portion includes a contact portion. The contact portions of the female and male portions are arranged to be engaged with one another when the female portion and the male portion are engaged with one another. The contact portion of each of the center conductors of the female portion and the male portion has a thickness of substantially half of a thickness of the remaining portions of the center conductors.
