The use of the Navy key wasn't so much a choice as of convenience: it's what I have laying around.

Has anyone attempted to repair
U.S. Navy - 26003A - Flame-proof Key? I had one to match up with my
SCR-274N setup but found the metal strip connecting one of the terminals to
the moving contact broken. It looks like a bit of a challenge to take apart
to access the moving contact.

Surprised you?re using a Navy key. The USAAF did have a flameproof key of their own.
