Simultaneously switches two isolated battery banks Review: After a lot of research these were determined to be the best for the job - We needed isolation switches for our campervan electrics and after a lot of research we found that these were the most highly regarded. They do cost a little more than the cheap replicas but are of much better quality and there is a reason that replicas are created of these in particular.

They do cost a little more than the cheap replicas but are of much better quality and there is a reason that replicas are created of these in particular. Easy to install considering we are noobs but that is thanks to YouTube. ### ⭐⭐⭐⭐⭐ Good quality *by B***R on 7 January 2020* Great quality, does the job! ### ⭐⭐ Not worth the extra money *by R***T on 3 August 2025* I have purchase both Blue sea and so called cheap knock off. Firstly the plastic mouldings are either direct copies or they use the same toolset. The mouldings marks are all identical even down to the blemish’s in the moulds. The switch operation feels identical and measured contact resistances are actually higher (0.2ohms) on the Blue sea product. People mention better sealing in Blue Sea’s product, I can’t see any seals on either product. The Blue Sea’s product also arrived in bubble wrap, no box! no instructions, guarantee card or any literature. At twice the price of an equivalent non Blue Sea product I’d say be sure you’re getting your moneys worth. ## Frequently Bought Together - Blue Sea Systems 6006 m-Series Battery Switch ON/OFF with Knob, Red - Blue Sea Systems 5026 ST Blade Fuse Block 12 Circuit with Ground and Cover - Blue Sea Systems 5191 Fuse Block Terminal 30-300 AMP --- ## 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.gr/products/68643563-300-amp-m-series-battery-switches](https://www.desertcart.gr/products/68643563-300-amp-m-series-battery-switches) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-25*
