Yeah, I've seen those Blue Sea switches. They would certainly work. I actually have a really nice Cole Hersee switch rated at 300A continuous, but I am actually looking for something a bit less bulky that will fit where I have the cheap switch located right now (see pic below). About the only place to put a bulky switch is under the hood, but having to pop the hood to get to it in a hurry sort of defeats the purpose.
Don't use that dinky switch as a cut-off for the main power.
They're not meant to handle the kind of load your winch is capable of drawing under a hard pull
The main difference between the cheap key switches and the larger heavy duty marine type switched is the way they make contact.
The key type switches basically push down on a thin copper tab that makes contact with a base (the turn of the key is just to lock the tab in place)
This type of connection is weak and simply can't sustain large continuous current draws without overheating.
Case in point, I had one on my Golf Cart as a main shut off using a cheap HF ATV winch and I ended up smoking the key switch
Not sure what the winch was actually drawing current wise, but all it had in the solenoid box was a pair of 40amp relays lol
The Blue Sea switches, on the other hand, have large rotating contact plates that slide into place as you turn the knob, creating a much better connection that can actually handle heavy loads
If space really is an issue, go with a large solenoid, mount it under the hood and either run a switch to your interior or use the same key switch on your bumper to activate it
It takes less than an amp to activate it, so it will be more than adequate :ylsmoke:
