AH!! That's where I read it... when studying for my CFI ride in a 182RG.
Thanks!

There also was a part of that AD that required an operational test in
which the key is forcefully (no torque spec but plenty aggressively)
turned CCW beyond OFF to see if the engine keeps running. Some
aircraft including our 172M, would relight again.

A new switch wasn't that expensive about 5 years ago (like $100). It
came as part of a kit replacing all of the locks in the airframe. The
tumbler setup and key etc was more robust that the Cessna OEM key.
