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 ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect. *by A***5 on 11 June 2026* Used on the electrics of our camper van; look to be well made with decent quality connector sockets and cable.
