I am just wiring my ceiling lights in my new home in Switzerland but noticed that they appear to be wired at random. I know that on most simple lights you can connect live-neutral & neutral-live but I would like the wiring to match up properly as I may add smart devices in the future.
I have the standard brown, blue, yellow/green on the lights themselves but on the ceiling the colours are purple, yellow, yellow/green.
Does anybody know where the yellow and purple wires should go? I guess I can safely assume that green/yellow is earth but would like them wired correctly.
