When were ceiling rose junction boxes invented? They appear to be post WW2 as I have been unable to find any that are older. The ceiling roses I have from the 1920s and 30s are either purely mechanical or have terminals just for live and neutral for the light fitting. Were ceiling rose junction boxes intended as a cost saving feature when constructing houses?
My Fowlers Electrical Engineer’s Pocket Book 1946 (effectively pre-war) cites as its source of illustrations and wiring diagrams for lighting, AP Lundberg and Sons Ltd of London. The illustrations seems to show two pin sockets an plugs. Presumably allowing light fittings both on stands and ceiling suspended to be moved around from room to room
