Light switch problem

[pkmjm]

Hi, I wonder if you could help me

My kitchen / diner has to sets of ceiling lights, one for the kitchen and one for the dining room. The lights are worked via a 1 gang light switch so both sets of lights come on at once.

The problem I have is that I have tried replacing the 1 gang with a 2 gang so I can switch on either the kitchen or dining room lights while not having to have both on. But I'm not sure what wire go where.

At the moment there are two cables coming into the metal box in the wall.Each cable contains a red wire, a black wire and a earth wire. The earth wires are conected to the metal box.

without a picture or description it could either be:-

1. 2 switch wires with the reds commoned and the switch wires commoned

2. the more comonly used nowadays way of putting the live / neutral at the switch and then to the light.. ( so one feed cable and one light cable.. )

3. one core of a T+E used as a feed with the black not used, the other T+E switching the 2 sets of lights.. or the other way with 1 T+E as the feed and switch to one light and a single core of the other T+E used for a switch wire to the other light..
