light wiring

[j9523johnp]

Hi, can any one help: I have a double light switch in the dining room. one ceiling light and a wall light and I'an stuck on wireing them up. I have searched the internet for a diagram but cannot find one. I have replaced the old 1mm with twin 1.5mm plus earth and an extra single wire. (there were 3 wires originally) I recently had a new consumer unit fitted and there was a fault in the dining room so I pulled all the wires out. I need it so that one switch operates the celing light and the other the wall light. thanks in advance.

Hi I'am new to this, I put 3 photo's on if you can see them, switch front. switch back- how it was. how i have tried. two live wires one negative wire but when I switch on both lights come on together.

I made the above drawing a long time ago to try and show all the different types used in a UK house.

The ceiling rose in the UK doubles as a junction box however when people buy European lights they often remove the ceiling rose and in doing so hide some of the wiring.

However from what you say can't really work out what you are trying to do or need.

Good work Eric, what software did you use?

I have sorted it. I did not want to experiment with 240 volts so I experimented with 12 volt. on the back of the double switch there are 2 connections at the top. one goes to blub 1, the other goes to bulb 2. the other wires from the blubs go to negative. on the bottom of the switch there are 4 connections: 2&1 2&1 The two connections "1" are looped. A wire from 1 goes to positive.

That's an odd way to wire it, but it will work just fine.

Domestic supplies are AC, not DC - there is no positive and negative - the voltage of the Line conductor with respect to Neutral goes from 0V to +325V to 0V to -325V and back to 0V 50 times a second.

yes i do know however no harm in pointing it out
regards john
P.S. I have added a photo to show how it is wired in the junction box
