Robust connection. Just make sure you can unlock your car with the key. Also with many cars before you isolate the battery put key in ignition at position 2 and leave driver door open or otherwise car alarm will sound when power is cut ### ⭐⭐⭐⭐⭐ Does what it says it will do. *by D***N on 18 February 2026* This does exactly what it should and does it well and is so easy to fit. ### ⭐⭐⭐⭐ 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. ## Frequently Bought Together - Spurtar Top Post Battery Isolator Switch 12V - 24V Kill Switch Battery Disconnect Terminal for Car Truck RV Boat Vehicles, Green Knob - Car Battery Isolator Switch, Heavy Duty Battery Power Switch Good Electrical Conductivity, Battery Master Disconnect Switch Battery Terminal Link Switch, Universal 1.7CM Diameter - Ampper Top Post Battery Disconnect Switch, 12-48 V Battery Power Cut Master Switch Disconnect Isolator for Car, Vehicle, RV and Boat (Negative, On/Off) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/91173780-spurtar-top-post-battery-disconnect-switch-12v-24v-battery-shut](https://www.desertcart.is/products/91173780-spurtar-top-post-battery-disconnect-switch-12v-24v-battery-shut) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-25*
