NOS 1957-1958 era? Mopar Headlight switch but exactly what does it fit?

I purchased a lot of NOS switches and this was in with them. I have the box but of course the useful tab is missing. I googled a ton of images and came up with no real matches other than 1957-1958 Chrysler Desoto switches look quite similar. Maybe it's Imperial? Although that it seems that would be the same as Chrysler. It does have 12 Volt stamped on it so that's 56 or newer except Imperial which could be back to about 52 or 53. Any wild guesses are welcome.

Sometimes the parts catalogs , such as Standard ignition or Napa , have illustrations of switches.

Looks like 1957-58 era with the push in connectors.

Good luck

I cam across one just listed on ebay last night. It looks to be 1957 Desoto.
