Unfortunately, nothing. The only characters are the 1-9 numbering the terminals on the back. I assume the switch handle is on backwards, assuming the bracket extension holds a light bulb. That's as far as my guessing gets me.

I was going through some of my 92 year old father's stash of rare parts and came across 2 of these switches. Can anyone confirm what type of switch and what it went on? I questioned my Dad and he had no idea, which is rare for him? I assume a GM product since he worked for Chevrolet from 1953 to 1983. Any help would be appreciated.

Who do I contact and address to receive my judging sheet for this show? Thanks in advance.
