The Dis-Car-Nect Car Battery Isolator 12v Terminal Quick Cut Off Switch + Fuse Link, made by Richbrook International Ltd in the United Kingdom, is a high-quality battery switch designed specifically for cars. It features a quick cut off switch and fuse link, making it convenient and safe to disconnect and reconnect your car battery. Suitable for all types of car batteries, this product is a reliable solution for controlling power to your vehicle effectively.
The only set back with this item after purchasing it as the perfect fit for my Mazda MX5 battery is that the clamps were slightly too large to be able to tighten them onto the battery negative terminal and the battery negative lead. Bear in mind that the battery is the correct MX5 battery and not a replacement by a different Manufacturer
I did resolve the problem however by inserting very thin metal shims between the clamps and the terminals in order to get a good purchase on the terminals. It took a while to find shims so thin.
Anyway problem resolved and the switch works very well.
