Random switches questions

Our light switch layouts are kinda crazy. No rhyme or reason.

Will be labeling all those in the cabinet eventually to make things easier.

I'm also swapping out some switch's wiring so they make a little more sense.

I have the same switches that are "Slideout Override". I figure they remove the power to the slide motors for manual operation.

Yeah I have already turned the switches and nothing.

I'm going home this weekend hopefully get me a ladder and my voltage meter and I'll get these switches figured out.

Now since there's no screws holding it there how should I go about taking the plate off so I can test those wires?

I eventually figured out all of my unmarked 12V switches by trying them out. A three-way for a floor level night light threw me off for a while.

They could very well be what you have suggested. These are almost certainly 12V switches for some 12V light or other device, and (if your RV is used) may well have been installed by a previous owner. Switching them would seem to be a good way to figure out what's going on, but I assume you've already tried that.

You could presumably use a test light or voltmeter to at least figure out what 12V circuit(s) they are powered by from the house 12V fuse box. Maybe you'll be lucky and it will be labeled helpfully. More likely, unfortunately, is that it will be labeled less than helpfully, unlabeled, or even labeled incorrectly...but one can always hope.
