Sure looks like it came from a stove.
I have a Diamond-H rotary surface-mount wall switch with a brass cover. Found it in a salvage shop for $5 about two or three years ago.
Facinating device and very elegant...and it's still in working condition, although I wouldn't want to hook it up nowadays!
P.S. Harold, thanks for explaining how the "monkeyface" is used!
