Abstract
An interlock device includes a shutter member disposed between a socket and a plug. The shutter member is coupled by a lost motion connection to the cover and movable therewith from a closed cover position allowing the plug to be inserted through an opening in the shutter member and into the socket to an open cover position preventing insertion of the plug through the opening and into the socket. The shutter member also prevents opening the cover when the plug is inserted into the socket.
