77 Argosy Wall Switch??

[argosy77]

My wife & I have a 1977 Argosy 28' center bath model that we're "reworking". To the right of the sink window, there is a 120v plug, 12v/antenna plug, and there's an on/off toggle switch above the plugs. I have no clue what the switch is for. Any help on this? I attached a jpeg of this that I found on the internet. Thanks.

On my 76 Argosy 26 , the switch turns the water pump off and on.

The water pump.

Water pump switch for potable water. The potable water door should be on the front of your trailer outside by the propane tanks and if yours is like mine the tank will be under the seating area at the front of the trailer and will be as long as the width of the trailers interior. The pump should be very close to that tank. If hooked up to power and no sound comes of flipping that switch, the fuse may have blown or you may need a new pump. My pump was recently replaced and the sound it makes by flipping the switch will make any unsuspecting person wet their pants. It’s startling if you’re not expecting it haha
