Incoming 240v mains supply or 240v from inverter on to the camper can system. **Q: Using as a camper hook up to invertor where will the earth go please, do we use a seperate wago or something** A: Yes, just connect all earths into a Wago connector or similar. Space is tight inside this enclosure. Also, be sure to buzz out connections and switching prior to wiring, the identification of the terminals is not overly clear. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality solid switch. *by A***R on 2 November 2025* I installed this in my camper, to switch between a battery inverter and mains. Get the the large back box version as wiring is made a lot simpler. I installed an extra gland as there are only two supplied. Wiring is straight forward, although the instructions could be a more helpful. ### ⭐⭐⭐⭐⭐ Good value *by A***R on 25 January 2026* Very cool item ### ⭐⭐⭐⭐ Work great, could do with a bit bigger casing *by D***G on 14 June 2023* These are a decent build quality. They only come with two glands, so be aware of that. Can't figure out how to install the included jumper bars. Really they need a bit more space to connect the earth cables, but they are much more compact than triple pole versions. They look tidy and have a very nice, positive click. ## Frequently Bought Together - Heschen Universal Rotary Cam Selector Changeover Switch, SZW26-20/D202.2D, 660V 20A, ON-Off-ON, 3 Position 2 Phase 8 Terminals, with Master Switch Exterior Box,TUV(Standard Box) - Leviton 5278-CWP Straight Blade Flanged Male Power Inlet Receptacle, 15 A, 125 V, Nylon Face, Body And Strap , gray --- ## 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/332855727-universal-rotary-cam-selector-changeover-switch-szw26-20-d202-2d](https://www.desertcart.is/products/332855727-universal-rotary-cam-selector-changeover-switch-szw26-20-d202-2d) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-04-25*
