The diagram of the light switch shows all the on positions ie. park, low beam, & high beam but it doesn't illustrate the OFF position. Lighting on most all the old Fords was independent of the ignition switch and could be turned on & off at any time. If a person only wanted the park lights on then all the others could remain off so as not to tax the battery while parked. Park lights were required to be left on in some states under certain conditions so a person wouldn't want anything else on that didn't have to be.


Ford changed things over the years with some dash configurations being similar to others. The toggle switch came & went over the years. Ford even used them for the rear work light on the tractors. 1940 was the first to go with a dash mounted head light switch. It was also the first to use a dimmer for those lights. I think the 1938 cars and 1939 standard cars had the toggle.
