A look at another item from the Matt collection of hardware, this one is an aviation style BCD thumb wheel encoder with a plunger action and incandescent illumination. Enjoy!

That looks very printable. I'm pretty confident you could totally print this.
So if it’s aviation then it’s probably 28v
If anybody wants to go a bit into the weeds on binary coding, "BCD" or 8. 4. 2. 1 isn't the only way. There is also 2, 4, 2, 1, "excess -3", and "8, 4, -2, -1". These are all called "self complementing" codes because of you if you complement any number the result is the 9's complement of the decimal number you are trying to represent.
if the C pin doesn't connect to other pins you might try reading its capacitance.
Maybe the C terminal connects to A while the button is pressed?
I can’t believe it’s 12V. I think 7V looks already overloaded (glare and bleeding) and too bright compared to the LEDs.
Depending on application this came from…
General aviation, typically 14 VDC
Commercial aircraft, 28 VDC
I wonder if you could lend one of these to Ben krasnow to do some x-ray analysis to try to figure out if that last pin does anything
Love these videos, Fran!
Does Fran have a Discord?
I really wish that I had found you years ago. We have many similar interests and now begins the binge watching of your channel. Thank you.
super cool
We really take LED's for granted. That much voltage for that little amount of light. Wild.
