Own a “Piece of History”! Or......buy one as a spare for your Warbird! This is an ORIGINAL World War II era Magneto switch in new surplus condition. These A.C. Type B-5 Switches were, and are, still being used in numerous WWII era Twin Engine Fighters, Bombers and Transport Aircraft such as B-24, B-25, B-26, DC-3, C-45, P-38 and others. These fit a standard 3 1/8" instrument panel hole. I took off the back cover showing the area where the wires get connected.The center “Flip” up or down switch is for “ON<>OFF”. That activates the two side “Lever Style” switches each of which have 4 positions; BOTH <> LEFT <> RIGHT <> ON”.
