OK, I think you have given me something to work with. I have a few old switches that seem to work with any key.. maybe they are not in the 'Lock' position.
So these ignition switches do not have an accessory switch...
With the settings of from the left: Lock, Off, On, Start...
With my 1966 truck. if I leave the switch on 'Lock', the GEN light glows dim and the battery will be drained if I leave it on this setting too long. This is why I thought it was an accessory.
