Of course. Thats exactly what it is. So which side is which? Im having trouble figuring out what one is the outgoing..... Is it labeled?

And yes, my post was rather non answer, but if you cannot figure out a switch, maybe it is something better left to the professionals.

There are plenty of other projects you can do that leave the rest of the people moored near your boats in less jeopardy when you do it horribly wrong.

What kind of draw is your autohelm using, is your wire sized accordingly? Where is the overcurrent device? These are factors to be concerned about when doing electrical work, having both sides of the battery hooked up to either side of your switch suggests that you haven't thought about these other concerns.
