Hi all, I took down an old boiler house at the back of the house. On this there was a single wire coming out to to the old PIR sensor which was smashed to bits. I'm trying to wire in a new one but I only have live, neutral, earth and no switch live. The old sensor looks to have had the earth wired into the switch but this seems wrong. Any advice?

On pir sensor you have in: live and neutral and out: live only. Lot of sparks use earth as output live as they are using only 3 core cable. Neutral is the same on in and out. Pir sensor don't have connection for earth wire.
