I wanted to install an outside light, hopefully taking feed from the nearby switch for my living room light, which is on the wall directly behind where I want the light to be.
I have a 2 gang switch, each with a Common, L1, and L2 connections. The existing single switch was the same but obviously with only one switch rather than two. The existing switch had a brown wire going to the Common, which I took to be the live feed, then a blue wire going out of the switch from L1. There is also an earth wire going to the metal back box.
The light fitting itself has a connector block inside with an earth wire in the centre, and a brown and blue wire each side. I have tried connecting the light to the switch by fitting the 2 gang switch instead of the single, then using a length of 2 core with earth, connected it to the switch by putting the blue into L1 on the second switch, the brown into the common on the second switch, and a bridge wire across the two common terminals which I thought would provide power. This does not work, but I was wondering if anyone can suggest a way that i could make it function, or even if it is possible without having to try to route another live feed through to the switch.
Any help would be really appreciated.
