Need some help selecting a big cutoff switch.

Find a nice switch to run a high amp solenoid

Probably not a good idea, and I'll explain why:

You'd have to wire it so the relay/solenoid is only energized when the winch is going to be used, but the current draw of the winch being used will probably cause enough voltage drop to make the relay drop out. Net result? Chattering and arcing which will quickly destroy the relay.

Now, if it's a dual battery system, and the two batteries are isolated, then the relay can go on one and the winch on the other.

X2, or you can look at marine battery selector switches.

X3. I wouldn't want to run the actual 2 gauge wire into the cab. Too much of a chance of something shorting it out/hitting and breaking it.

Y'all don't use fuses?
It's no different than sub/amp wiring...

I want to keep it simple, but I do kind of like the idea of a small wire in the cab instead.

We don't need no stinkin fuses.

I look into the solenoid thing a bit further. I was trying to keep it simple, but a single power wire running into the cab sounds easier to install. If I do go that route, I am guessing I do not need a fuse.

You should always run fuses...

 

[Lonesome7.3]

What type of solenoid should I use? Where in the line should the fuse be? In the wire to the switch? Or do I run a large one on the cable?

 

[Draenor]

Solenoids usually are for high amperage applications and are not fused. If you were to use on it will need to be rated pretty high.

You can always run a fused circuit to the switch lead.

I have a bunch of these lying around.

Would that do the trick or is there a difference? It would be nice to use a stock piece.

I don't see why it shouldn't.
