Whatever you do don't let Ed Storey know!!!
Polishing copper and brass with that patina will never bring it back to as-new. It tends to over polish the flat surfaces which accentuates the dark in the recesses and scratches. Given the apparent scarcity of knife switches, I'm thinking more and more about making them with new material unless somebody has a stash of them somewhere.
