For my current build I'd really like to use a plain brass (not "gold" or polished) AV switch with a purple ring. I've found plain brass switches, but only from a UK supplier, but the only switches I can find with a purple ring are either black or chrome. I believe the material is brass, but I'm not sure if it sanding down would be a reasonable way to get to the brass layer underneath. If anyone has any insight into what kind of result I might expect, I would greatly appreciate it. Any thoughts on weather it'd be easier to start with the black or chrome?
Failing this, I may attempt to fabricate a switch using a hole saw to cut a disc out of the the tubing then rig something up with a contact switch.
Thank you for any input you might have!
