Abstract: A socket provides power to a mating connector plug when actuated by a switch integral with the socket. The switch can be actuated by insertion of the connector plug, by pivoting open a socket cover, by sliding a slide cover into an operational position, or by a combination of the above. The switch is isolated from the power supplied to the socket and acts as a power supply signal to enable socket power. The socket is powered only when needed as indicated by the actuation method, thereby reducing draw on a power supply connected to the socket. The switch actuation methods described also provide safety features by disabling power to the socket unless the socket is actually in use. The socket cover and slide cover also prevent access to the socket unless positioned to receive a connector.

Abstract: A fused mechanical interlock in an electrical switching device precludes a fuse access door from being open when the switching device is energized.
