## Description

Spurtar Top Post Battery Isolator Switch 12V - 24V Kill Switch Battery Disconnect Terminal for Car Truck RV Boat Vehicles, 2PCS : desertcart.co.uk: Automotive

Review: Super easy to fit. - Nice quality units. Very easy to fit, less than five minutes once bonnet is up! Works well, switches on and off easily. Arcs a little when switched on as expected so with prolonged use may need cleaning on contact surfaces. Don’t over-tighten battery terminals or it may snap or damage when fitting. Keep it clean so no electrical tracking can take place which would cause slow discharge of battery. Make sure that there is room for it to fit next to the battery. Only fits on the negative terminal, makes it a little safer for DIY fitters when using a spanner near the battery, -presuming negative ground vehicles! Should increase life of battery as a good battery will only need a top-up charge occasionally. Definitely slows discharge times. Wish I had found these years ago instead of taking the terminal off every time!!
Review: Great! - Fitted on a Renault Convertible. It is working great!

## Questions & Answers

**Q: In the description it says "Brass battery switch made of heavy duty solid brass", but when I had to file down a rise, the brass came off?**
A: If it says solid brass it should not flake off it should be brass through and through I would send it back mine is not like that

**Q: How did you connect your original cable "to"  this? Its just a hole on that end!**
A: Your original cable should have a "horseshoe" fitting that attaches to the post on the battery (if not I am not sure what you would have or if this would work). That horseshoe fits round the post end (not "horseshoe" end) of the disconnect switch. Hope that helps.

**Q: Will this work for a 48 volt golf cart set up?**
A: Note the product description says it is for 6-24V.  Sometimes switches can be used outside the design spec, but when used at voltages above spec it is possible to get arcing, pitting, premature failure, or welding of the contacts.  I would look for a within-spec solution.

**Q: Would this work on a hybrid 2007 Saturn aura?**
A: It will work anywhere there is a battery terminal.  Look on YouTube.

### ⭐⭐⭐⭐⭐ Great!
*by F***0 on 31 December 2025*

Fitted on a Renault Convertible. It is working great!

### ⭐⭐⭐⭐ Works well, tight fit in confined space.
*by R***O on 24 November 2019*

A good switch mechanism which isolates my main camper van battery when it is in storage. However it was quite a fiddle to fit because of it's length in the tight battery compartment and with the arrangement of the terminals. Check this before ordering.
