Mystery Switch

[campIV]

Does anyone know what this switch is for? It’s a three position switch to the left of the water pump switch. All three terminals have a wire attached. The red wire is +12vdc. All three wires run through the cabinet below the stove and disappear behind the fridge. I haven’t found anything that changing the position of the switch affects and there’s no information about it in the original manual that came with the van.

I’m thinking of pulling the wires off the switch and insulating them because I’m uncomfortable with having a possible short circuit develop somewhere. Any input would be greatly appreciated.

Van info:
1997 Sportsmobile, Ford E250, RB50, manual pop-top, 5.4L, 2WD, propane stove and furnace, 12/120 fridge, electric water pump. No water heater or inverter.

Please note that for some reason the first picture posted upside down so the switch in question appears on the right.

Thanks again,
Fritz
