I currently have a switch on the landing to turn off the light. There is also a switch downstairs with an existing 3 core and earth wire running upstairs to the upstairs switch.
I just need a little help on how to wire the downstairs switch into the upstairs one.
The image shows how the upstairs light is wired. I hope this makes sense.
