Thank you so much for your help, Nitrousn and all👍 Your pics and descriptions were perfect😀
Guess what: I stumbled over a steering wheel from a 68 Charger in the parts pile and it had the switch I was asking about intact👍 Correct parts number, but has some cracks in the plastic. It is now installed in the W200 steering wheel and works as it is supposed to!
Here are a couple of pics of mine. You guys rock!
