This is a deviation from my usual nature based posts and is one for the historical electrics geeks out there. Going through Grandpa Ratz’ impressive collection of tools we found this handy gadget; a Loblite Fitall plug.
By moving the black plastic lever, brass pins would drop down in different configurations to fit into the varying types of sockets that were around during the 1960s. Apparently there were 5A, 13A and 15A sockets in those days. From reading discussions by people who used Fitall plugs it seems to be an electric shock waiting to happen.
It also seems to not live up to its marketing hype either; I quote from the wonderful Museum of Plugs and Sockets: “The Fitall plug is useless for Wylex or Dorman & Smith sockets.” So much for fitting all! You can read many more details about this plug, with lots of photos of one taken apart here.
