  • Patent number: 4066322
    Abstract: A male contact assembly for high voltage switching applications includes a male contact with an electrically insulative member arranged concentrically with the contact and extending longitudinally therefrom. The insulative member has a hollow interior adjacent the contact and a solid electrically conductive element in such hollow interior is in electrically conductive connection with the contact. Arc-quenching material overlies the insulative member and, on fracturing of such material, the insulative member isolates the electrically conductive member therein and the contact from electrical arcing.
