38 "Steering column light Switch"

Yes, the column is essentially an on-off device only and the floor is dip only.

Dave,
You have it right. The column switch selects off, parking lights, or headlights and parking lights. When the headlights are on, the floor switch selects low beam or high beam. The switch on the dash only operates the instrument lights. It is only live when the column switch selects either parking lights or headlights and parking lights.
Pulling the column stalk toward the wheel operates the "flash to pass" function.
All the best,
Paul

While I understand that the original question did not necessarily ask the question that we finally got around to giving a good detailed answer for (good job Paul) , and newbies to a specific year car may not know exactly which question to ask, it seems we may have collectively done a better job of getting the info to DALE that he needed. I apologize for my failure to provide the same info back when I first responded - I knew this answer at that time but just assumed more than I should have.
Now I think we need to help out a bit more with the "which wire goes where" issue, if he still needs that help.

Let us know.
Dan

(ok, ok, typo fixed)

Thanks everyone... since there is floor switch (nor is there a mount on the pans that were installed) I might put a push button that would do the same function on the dash and wire in the column to do it's original feature (now that I understand Lucas' wiring plan for that part)

For further information (hopefully not confusion), there appears to be a 4th type of switch.
My very early car has 2 position dash switch (lights on, lights + dash lights on), with 3 position column switch, (sidelights, low beam, high beam) but with NO flash to pass function.
All my other Spits have had Flash, as did the 2 Lotus and the Canstel that all use the Spitfire based switches.

I had no idea that Spits ever came with a floor mounted switch.
They are an abomination, impossible to operate if you are 'busy' dealing with braking and downchanging into a corner, which is just the time you need to dip, with someone appearing around that corner.

I had a much missed 1970 Falcon GT, and that floor mounted switch was about the only thing I did not like about that car

Marcus,
To the best of my knowledge the floor mounted switch was used on the North American market cars only. Other markets got some variation on the column dip switch.
All the best,
Paul

I was just looking through a pile of diagrams and have 4 that are specific to the Mk1 and 2 cars, part US and part UK. The European book diagrams do not show any floor switch. The Haynes manual, that does not title the diagrams as US or not US, seems to indicate an option like Marcus describes, but which lights go on with which switch may depend on the positions of the two switches. (Some of the Haynes diagrams seem to have wires feeding back to themselves in the switch so I am not secure in using them).
And, some of the switch diagrams give no hint as to what circuits are activated at the same time, or not.
But from first look, it appears that all the US diagrams show the same setup for Mk1 and Mk2 cars and then the change with the Mk3 to no floor switch.

I wish I had a magic wand so I could take them all and design them as similar layouts for comparisons, then extract just the lighting circuits to cut the clutter. I just don't have the time to do it otherwise.

Ok, I found a little time to do a little work. Attached is a .pdf showing 4 different column light switch diagrams. I think the actual wiring of the switch only has two basic setups but what happens as a result of the switch to and from those terminals may vary. That is the part I did not have time to do yet. As I mention on the document, they do suggest that in the early cars there were actually three positions as a couple of mentioned; off, high and low (plus maybe other side things). Others interpretations are welcome.
