1940 chev special deluxe headlight switch original wiring

Got a original switch I’m working on. Yes I know I can buy new but I’m not after that. Just wanting to learn about the wiring paths. Wondering if anyone has one like this and how she’s wired?

 

I hope this is posted in the correct spot. Anyone wire one of these round ones? Just wondering about how it was wired originally

Thank you. I’m also researching the original key switch. There was no motor in the car when I got it. But this steel tune that runs from the back of the key into the engine bay with a round cup at the end and a single wire inside. Kinda wanna learn more why this was done like this or what exactly was the reason

 

The armored conduit made the car "theft-proof" .

 

Ohh I understand. Cool cool. Thank you!
