1957 ignition switch correct wiring

[valhalla 4771]

Trying to re-wire everything. Discovered my ignition switch doesn't match up with my full color-easy-to-read ClassicCarWiring diagram. The diagram shows 4 terminals S, AM, C, and AC. My switch (see photo) shows BAT, ACC, ST, and IGN. Do I have the correct switch? If not, I'll order one. In the meantime, can someone match up the two labels for me?

When you post to the forums, your subject should summarize what your post is about. "1957 ignition switch" could be anything, selling one, buying one etc. I will revise it.

Batt = AM
ACC= AC
IGN = C
ST = S
Looks like an aftermarket part
from the back side it looks like an original
if it fits into the dash properly
It should work
