Light Switch on Farmall H - Which One?

I have a 1952 Farmall H and I'm trying to figure out which light switch I need. From what I can tell from doing some research online and by what external link tells you, if you have a 6V voltage regulator, then you need the switch that doesn't have the fuse that snaps in the back and then you have the separate fuse holder.

If that is the case, then I have a mis-match (see pictures). When I got my tractor after my grandfather passed, the lights didn't work. I have the rear lights working and I recently connected the front lights and things got hot and smelled like plastic was cooking. I have a guess that my grandpa may have installed the wrong switch at some point and just wired it to make it work. I'd like to get a new fuse holder (and wires, they are bare) and a new switch.

Can anyone tell me why this isn't showing any text in "Modern View", but it shows up in "Classic View"?
 
Well, I couldn't get this post to work on "Modern View" the first time so I'm going to try to put the original info out there again as a reply. Sorry about the duplication on "Classic View"

Modern view filters out content with "undesirable" content. In this case, probably whatever you put in that shows in classic view as "external-link". You could probably see and correct problems like this if you did a "preview" and checked what displays back before you post.

Back to your original question, it looks like you currently have the earlier style 4-position "L H D B" switch and your tractor originally had a 3-position "O D B" switch.
 
3-position switch is correct for a regulator-equipped tractor, which is basically anything after about mid-1950. So yes, your 1952 should have a 3-position switch to be correct.

A 4 position switch will function perfectly well, except that it will have two "OFF" positions on a regulator tractor.
 

Thanks!!! The only thing that might have been objectionable was a link to a competitor's parts website. ;)
 
Sounds like you got it figured out. 3 position switch is what you should have. That would
be correct for a voltage regulator. For future information, the 4 position switch was for
the cut out system that the voltage regulator replaces. They had a low and high charge in
conjunction with the light switch on the cut out system. If the lights were on at all, it
was on high charge.
