The mounting holes and posts for the terminals make it awkward. Aside from that it’s great. ### ⭐⭐⭐⭐⭐ Easy and it works *by L***E on March 24, 2024* Installation is extremely easy, simple operate and reliable. Use as added security on my ‘57 Chevy. ### ⭐⭐⭐⭐ Worked well *by B***O on February 6, 2024* This master switch works well but the keys are made cheaply and there’s a bit of wiggle room in the locked position, they work though, and for a good price. ## Frequently Bought Together - OCR Battery Disconnect Switch with Keys, 2Pcs 12V-24V Battery Kill Switch Isolator Disconnect Cut Off Power for ATV Car Auto, On Off Battery Master Switch with Waterproof Key and Cover - TKDMR 160Pcs Copper Wire Lugs AWG2 4 6 8 10 12 with Heat Shrink Set, 80Pcs Battery Cable Ends Ring Terminals Connectors Tubing Assortment Kit - GOGONFLY 2PCS Battery Disconnect Switch, 12V 24V Battery Isolator Cut Off Power Kill Switch for Marine Car Boat RV ATV Auto Truck Vehicle, On Off Battery Master Switch with Waterproof Key and Cover --- ## 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.dk/products/28581396-battery-disconnect-switch-with-keys-2pcs-12v-24v-battery-kill](https://www.desertcart.dk/products/28581396-battery-disconnect-switch-with-keys-2pcs-12v-24v-battery-kill) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-05-15*
