The Battery-Disconnect Switch was just what I was looking for and it was fairly easy to install as well.
Patrick Simmons
Product appears to be made of heavy metal however it is brittle when I attempted to tighten it so it would be secure on the post it broke in half at the bolt.
Ray Z. Dissinger
When I tried to install this on a side post battery there are in sufficient parts to complete the installation.

Inexpensive but well-made, this Disconnect Switch is simple to install in a couple of minutes. We put one on my wife's minivan to secure it after an attempted break-in and it works great! Unscrew the knob about one turn and, while a small amount of current through the fused jumper maintains radio and other memory functions, high-current functions like the starter are totally disabled.

Unscrew the knob completely out of the switch and take it with you for maximum security and as a reminder you have disabled the system. My wife has already blown two fuses, forgetting she had disconnected the battery. It works as advertised: but with the switch open, turn the key, the fuse blows, everything goes dead, and you spend the next ten minutes re-programming the radio. Popping a fuse doesn't hurt anything, but volatile memory will disappear. You can still tighten the knob, closing the switch and start the engine, so it's only a convenience and not a safety issue.

If you buy one of these switches, lay in a good stock of 15A mini fuses too . . . you will blow several before you learn the new starting drill!

My wife's 1981 El Camino has an electrical problem that drains the battery after a week or so and we've been unable to find the cause. This resulted in having to replace the battery every year as it'd get to the point where it wouldn't take a charge.

I ordered this bit of hardware in the hopes that it'd save the battery. It did.

Installation was easy... the adapter for side mount batteries worked fine, but I did have to spend a nice chunk of change at PepBoys for a post adapter for the other end of this switch.

The end result though is that when my wife gets home at night, she raises the hood, turns the knob and knows that the battery will be charged the next time she needs to drive the car.

If you have a car that doesn't get driven often, or has an electrical problem as I've described, I think this is a great solution for a reasonable price.

It should be simple, disconnect old cable,put this on, and reattach cable.
However, the terminal post for the cable is too small for normal battery cables. No amount of tighting the cable bolt will firm it up for a decent connection.
I've tried two different kinds of these to install on two different cars, and both have the same problem.
Now, I'm out to find some soft copper sheeting to make up for the difference.

The switch itself seems quite solid and simple to use. If you're not concerned about the memory settings maintained by the jump line [this draws current too], get a cheaper one for $11.99.

I believe the claims to fit both a side post and top post battery are very misleading and inaccurate. Since I live out in the country, I bought this thinking I could install it without additional parts. As well, the fused link defeats the purpose of a battery disconnect. When I tried to install this on a side post battery there are in sufficient parts to complete the installation. There is no way to connect the cable to the other end of the switch. To use this I had to travel to town (I live 50 miles from town) and get nuts and bolts ($2.20) to get it to work. I you install the fused link, then you still get battery drain from the on-board electronics and within a short week (at least in a GMC pickup) the battery is dead. I do NOT recommend the purchase of this switch for a side post battery.

I bought two of these items. One did not fit onto my 2006 Corvette battery because of the positioning of the battery so I returned it. The one I kept I placed onto my 2002 F150 and use it often!! I went through three batteries with the truck sitting before I installed this and since then I haven't bought another battery!! I do not use the fuse functions for memory saving purposes because I was afraid of draining the battery while the truck sits for long periods. I would recommend this product to others.

My car tends to sit for long periods and this switch is perfect. It installs easily and saves my battery from the constant sitting.

great way to save your battery when car is not used for extended period. Fairly easy to install. Stays permanently on car so you don't fuss with battery cables or trickle chargers. Price was reasonable.

This item has proven to be an excellent product. I no longer have problems with the RV's battery going dead.
