3 WAY SWITCH adding new lights.

[strictly]

I have and existing 3 way switch on the wall that controls the upstairs light, lounge light and a porch light. There are two twin and earth cables and a single that enter the switch. The first one - Red too 1 WAY - Black too 2 Way (at top right). The second one - Red too Common (bottom right) - black too 1 Way (top left). Single cable connects too 1 Way (bottom right).

2 Way 1 Way Common 2 way 1 Way

Common 2 Way 1 Way common

I have put a new light on an existing wall. I want too get rid of the porch light and put the new light onto this switch so it will eventually switch upstairs light, new light (2 wall lights), lounge light.

If i get rid of the second cable which is the feed and give it a new feed, but with the neutral wire connecting too the live connections on the wall lights, will it work.
i.e.

common................................live connection.
1 WAY...................................Live on light on wall.

suggestions would be a great help. cheers.

sorry, but i don't really understand your description of current connections - can you draw a diagram and post it online? it'd make it easier.

But please note, that none of the wires in your switch are neutral, even though there are black wires. they're all live or switched live.

as i cannot upload a diagram this is the best i can do

2 way --- Nothing conected
1 way ----------- Connected to the Live terminals on the wall lights. (Black)
Common --------- Links too all other Commons.
2 way -------------- Connected to upstairs light. (black).
1 way --------------- Connected to upstairs light. (red).

Common --------- Linked too other commons.
2 way -----Nothing connected.
1 way ------------- Connected too single wire from lounge light.(Black)
Common ------------ Connected too other commons. and also feed that i have brought in. Red wire.

2 way 1 way common 2 way 1way


Common 2 way 1 way common
