Questions & Answers

Would it not be possible to move the post to the other side, so that the contact blade makes contact on the other ?

The answer is yes

Is it possible that the lever contact will become loose if I use it all the time?

JPC - It is hard to say for sure, but I am confident it will last a long time.

Can you tell me what material it is?

This brass piece is made of

This switch looks like it will raise the post to which the battery cable will attach, how much will it raise the post when it's installed on the top of the battery?

Honestly, I have no idea what it would be like. My guess would be about the length of the original battery post plus a tad more. I found that it fits well on my 2010 Honda CRV and that there are tight clearances.

The bolt was the wrong size, so I had to remove and replace the throw arm and switch sides of the plastic mounting base to make it work for my application
3/5

As a result, I have a few other types of battery cut-off devices since the supplied bolt wasn't the right length. In case the supplied bolt was not long enough, I used another bolt from one of the other cut off switches I had. They supply you with an extra bolt (smaller) that should have been used with the different style battery cut off switch. I guess they make them both and just thought it was fair to include a smaller bolt The fact that everything is made in China is also a major turn-off. In this case, the switch itself is fine, but I had to rearrange the bolt length on the leave and catch sides in order to get it to function.

This is something I have needed for a long time
5/5

During the past two days I have had two garaged days Over the past 20 years, there have been many driver sports cars. It seemed as if the battery had been drained within a few weeks and a jump was required. Most of the time, I didn't drive them far enough to fully recharge the batteries if they started. My eyes lit up when I saw these levers Although there were other options, we chose to use the quick-charge battery There was a start kit to deal with, but it was overly complicated. There is a rigid component to this machine. It's easy to use, I just open the hood, flip the lever and let it hang until I need it again. As the battery of my C6 Corvette is in the middle, I had to unscrew and rearrange the connectors to make it fit. As I might have mentioned, I figured it out with my wife's help, and it works great now. Seeing the pictures made it hard to tell how well the lever would stay closed, but I'm sure it won't be an issue over bumps, etc. There is nothing I don't like about what I see so far. And its so cheap!.

The result isn't too Overall, the hotel is decent for its price
4/5

Since the metal was already flaking off before i was able to get it set up, it could have been coated better. It would be better if the base was reinforced a little better, since we have a few cold winters coming up in the Northern Hemisphere. However, it seems to be going well so far.

My post was too big for it
3/5

Either the hole is too small or my post is too big to fit it over. There's only one possibility if you had a small post, or if you could make it smaller, or if you increased the size of the hole. Trying to spread it open a little caused it to snap. My hand didn't even force the glass to break and it split in two. Thank you very much! I got my money back right away, and I am grateful! It was a pleasure working with.

It is a high quality product
5/5

This switch works well. Upon looking at the bottom plate, I was pleasantly surprised at its heft. This blade is installed in minutes and is smooth to move. The product is great, I'd buy it.

I could not get this to work with My Ford 4000 tractor did not work with this configuration
3/5

It might be working for some tractor configurations. A lid cannot be closed inside the tray without shorting out because there isn't enough room inside. As well as that, it's hard to release it.

The switch does its job better than most others
5/5

There are vehicles that I do not use very often. When the battery is not used frequently, the battery drains. The off/on switch allows me to disconnect the batteries on my not-used vehicles, then reconnect them easily. It is commonly used for collector's vehicles. In addition, this would make it much harder to steal a car.
