Does anyone know what these marine radio pot/switches are or what they do?
So, Oskar Skog, you were spot on! I ended messing around with the multimeter and yes, it changes the resistance with the rotation and the click is a switch to a different set of terminal on the underside. Also, while messing around with it, I discovered the name ALPS Japan on the back. I was able to find the website. I'll post it just in case anyone else else needs to know or is curious. But it is either a 50ohm, or 100ohm potentiometer with a max rated power of .05w
