The left of center deploys the propellers when you drive into a lake or river. The one to the right of that allows you to hear about yourself on the radio news.

There may be some truth in that post (last half)
1: Boost/Emergency Start/Aux Start as someone else said this connects the chassis and house batteries when pressed to give you a built in jump start... Often needed on older rigs where the house does NOT charg the chassis. This is ifthe switch spring returns to off.. If it does not (If it is a straight toggle) then it is a battery disconnect.
2: Fans.. Not sure which but likely the two high mounted defroster fans
3: Radio battery selector (This is the true part) So you can run the dash radio off either HOUSE or CHASSIS batteries and hear about the briallent thing you did on your way to the campground on the radio.
4: Spare/blank/user defined.
