Battery disconnect switch

Where is the best place to get them? I have been meaning to get them for a while. TIA
You can get them on Geo's favorite site, and ebay and a million other places. Some of the best HD units I've seen were sold by Cole-Hersee.

In the photo are a light-duty versionI installed several years ago on a DEERE "318" and I'm holding a heavier-duty unit in my hand.

Pollak sells good HD units, as well. Apparently, the larger unit in my photo is actually a Pollak.

The wiring diagram provided by Pollak is interesting vs. the views of some here
 
I have one of the Cole-Herse hd's on my Ford 851. Empty hole in the dash just above the ground cable made it neat and easy. From Amazon and not cheap but it's quality.

No good place to put one on the International 424 so I used a blade type on the battery post. It's ugly but it works. Got it at RK.
 
There are good ones but not generally sold on eBay or Amazon. They come from the Land of Almost Right. I like the ones NAPA sells.
 
You can get anything you want on eBay or Amazon
Many different designs and some for side posts.

This works just fine for me. Have 3 tractors and Toyota Tundra hooked up with them and they all work. Last for years. Steiner has them. Fleet Farm has them.

I got one like that on Amazon for my Farmall C. Put it on the negative side and seems to be working ok so far. The price was right.
 
If you want a high-quality switch, look at those intended for marine applications. These switches are intended to keep working after they've been repeatedly doused in salt water, a far more severe environment than your typical farm tractor.

Blue Sea Systems makes a variety of switches in different configurations and ratings. And unlike most brands, theirs are fairly compact. The Blue Seas 'mini' switches are rated at 300 amps continuous, 500 amps intermittent. They are designed so they can be either surface or flush mounted.

They seam odd if you get crafty they make for a clean instillation and work well. This is a cheap one they make them with a voltmeter indicator now.
