  • Patent number: 6051788
    Abstract: An electrical outlet safety plate is configured to preclude simultaneous contact of the fingers of a person with the electrical contact prongs of an electrical plug, when the prongs of the plug are also in contact with the electrical contacts of a receptacle protected by the present safety plate. The plate has a depth which is greater than standard, preferably about one half inch. The electrical receptacles of an outlet protected by the present plate, are correspondingly recessed below the outer or front face of the plate. The receptacle access passages through the plate are configured to fit closely about the periphery of a conventional electrical plug having generally curved opposite sides and straight, flattened top and bottom surfaces.
