    Take a closer photo and try to get any part numbers in there as well. I'll take an off the wall guess that they are switches!!! But maybe they are pots... I dunno. Can you rotate the white knobs? Do they make a clicking sound at one extreme?

    With 4 legs it could be a switch, or a pot with a switch. Can you feel detents when you rotate the shaft?
    If it's a pot it will have some numbers marked on it. Tell us what they are.
