A negative battery isolator ( 90° rotation ) that simply mounts inline between the post and your negative connector.Best fitted to batteries with level posts, or perpendicular for recessed posts.A well sprung copper moving contact rotates onto the iron post terminals to make or break the circuit.A brilliant idea that’s easy to fit and saves changing cables or connectors.

At the time of this review this battery isolator switch was £12.88. Installing was very easy to do: remove the negative cable from the battery, attach the switch to the negative terminal and make sure the isolator switch is turned to the off position, attach the negative terminal cable to post on the isolator switch, now turn the isolator switch back on and voila, job done! Note on most cars, the negative terminal post on a car battery is often smaller in diameter than the positive post terminal and it should fit fine. Look at the images in the advert relating to sizes and double check the battery terminal sizes and room around the battery before purchase, just to be safe.The reason for deducting one star is that the description for the product in the Amazon advert indicates the connectors on this device are pure copper. I have never seen shiny gold coloured copper before, I would guess these are a zinc copper alloy of some sort. In addition the written instructions on the accompanying leaflet inside the box are totally confusing and indicate it should be mounted onto a backplate using bolts... nope, that isn't how it works at all. It is simply designed to rest on top of the battery and is secured on the battery post.I installed this in around 5 minutes on an old sports car that is constantly draining the battery when not used for a while. So far I am really happy with it.
