Thanks for the replies so far guys....i always thought you couldn't fit a dimmer on a 2 way circuit.
What i have is 2 switches in my front room, the first switch works the front room main light. Then in the dinning room section i have the second switch, which is a double switch. Id basically like to convert both to dimmer switches, im not that bothered about, the second ( dining room siwtch ) working both ways......If its a pain to then i may just opt for the front room main light to dimable.... so could i just fit a 2 way dimmer where the first light is??? any comments?...thanks again guys.
