it would take you both hands and both feet to count up all the times this question has been raised and argued over. Some have to have the knife, and some like me love the **** from LICS.
here is just one discussion. If you search battery cutoff you will find many more.

Not so lucky - I've had two green **** failures AND not cheap versions either. Seemed as time went on I had to crank down on the **** tighter and tighter to get connection. Then it wouldn't connect at all. Corrosion apparently.
My cars run the knife blade switch now. Some seem to get away with the green **** mechanism - I didn't.

The **** takes a while to screw close or open. The knife takes a couple of seconds at best to close or open. There is also no guessing if it's tight or not. It's either on or off. After having the **** fail on me once I have gone to the knife. It's fail safe

Trust me, I wish the **** worked for me; the knife blade is ugly and takes more room but its bulletproof

Yes Frank and the knife doesn't like a wrench dropped on it the wrong way either.

The positive or negative cable thing has a million opinions. I prefer the negative cable which prevents shorting the positive terminal to ground if you drop something on the battery (not a big deal on a C2). Provided that your car will shut off when the neg. cable is pulled off the battery.
In some cases, the ground to the alternator will allow voltage to still go to the ignition system and the car will still run with a cable removed. This is more of a concern when the switch is used to shut off a running car (race car). And you can get this switch with alternator protection for shutting down when running.
If I put one in my 67, it will probably be close to the battery and just used to prevent discharge and a little bit of theft prevention.
The red key is removable.

Steve, you can mount these pretty much anywhere you can run the battery cable to. Obviously with this switch, you have to spend 20 minutes and make up 2 cables.

my black **** has been foolproof for the last seven years, on two cars. Takes less than 2 seconds to screw down three revolutions. I don't guess if it's tight or not. I can tell it's tight when it won't turn anymore.
This is not rocket science.
I'm sure the knife is just as easy, but it looks like hell. Why use it?

That would give you the added advantage of being able to kill the electrical quickly, in case of a fire. electrical short, etc.

I have a few of the ***** and have had good luck with them. My initial thought was to remove the **** completely during long term storage - good idea, but it was a huge PIA to get it screwed back together on my'66 due to the mounting location! Now I just partially unscrew it even if storing the car for the winter...
