Batt disconnect switch help

The disconnect switch that was in my truck was a POS. It had a screwy connection or something so it was constantly disconnecting on it's own. I have it bypassed right now but plan to replace it. Is there one that is better than others or are they all pretty equal. The Blue Sea ones look sturdy but I liked having the option of turning it off and pulling the stem out if I am leaving the truck somewhere. Any advice is appreciated.

Jason

Is the disconnect for the starting battery or a winch battery? One for a winch battery would require a higher capacity.
What I use for a winch is described here: http://siteground237.com/~gunsandr/s...ull=1#post9778
It's a Cole Hersee 2000amp, but they have a wide variety of lower rated ones that would be suitable for a starting battery.

Right now it's just a starter battery but I will be adding a winch and lights soon. Can I get one switch that has multiple settings or do I need different switches for each function? I saw some Blue Sea ones that have a panel with multiple switches. I will be sticking with one battery, I have the big Die Hard Platinum marine battery

If you are running a winch off the single battery a two position (ON-OFF) switch is all you need. If that's your plan I'd go ahead and get one that has the capacity to support a winch, like the one I referenced. A few other companies make them as well, including Blue Sea I think.

I don't know about the Blue Sea one, but the keyed Hella ones I've seen were just a simple stamped key that isn't very secure. Cole Hersee makes some with a key like the Hella and also some with "real" keys. I prefer just using the 24505 lockout with a padlock.

Just out of curiosity, where are you coming up with that 2000 amp figure? What I mean is, on what basis you choose that rating?

Also, for those of you who are putting in a battery switch, what is the reason? Theft protection? Fire protection?

I'm adding a winch right now so I've been mulling these things over as well.

It's 2000A intermittent (30 sec) and goes down from there to 300A continuous. Cole Hersee sent me a graph of the capacity/time rating and IIRC it was 500A for 10-15 min. I figured I'd not be running any of my winches for anywhere near that long at 500A.

I use them primarily as an emergency shut off in the event a solenoid or controller switch sticks in the on position.
