  • Patent number: 4037901
    Abstract: An electrical safety socket in which there is no electrical contact between the socket and a plug inserted in the socket unless the plug is properly inserted in the socket, pushed in, and turned. The plug, once inserted in the socket, cannot be removed unless the reverse sequence of operations are performed. This precludes electrical contact if a child should insert a foreign metal object in the socket when the plug has been removed, or prevents the plug from being removed from the socket once inserted.
