Push a button to start, then push a button to stop?** A: noo. you don't have to push any button , it start automatically and stop automatically ,, ( by current ) **Q: Will it be able to switch a 36v main with a 12v signal input?** A: It's rated 12 volts so unlikely. Fine for car spot lights or in my case heated windscreen. **Q: From what I know of relays, the diagram on this listing shows incorrect wiring. Can you confirm please?** A: Hello, the diagram on this listing shows is correct, pin85 and pin86 can connect battery and ground in reverse ## Frequently Bought Together - Gebildet JD1914 12V 40A Car Relay with 12AWG Harness Sockets, 5 Pin SPDT Relay with Color-labeled Wires for Automotive Truck Van Motorcycle Boat (Pack of 2) - Gruiqrd 12 Gauge Silicone Wire, 12AWG Electrical Cable 32.8FT/10M [16.4FT/5m Black and 16.4FT/5m Red], Flexible 680 Strands 0.08 mm of Tinned Copper High Temperature Wire for RC Car, Marine, Airplane - JatilEr 16AWG Inline Fuse Holder 12v 2 Pcs, Blade Waterproof Fuse Holder Copper Wire with 15A Standard Fuses for Car/Truck/Motorcycle/Boat --- ## 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.co.za/products/58831489-2pcs-jd1914-car-relay-harness-12v-40a-5-pin-spdt](https://www.desertcart.co.za/products/58831489-2pcs-jd1914-car-relay-harness-12v-40a-5-pin-spdt) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-09-18*
