We want to replace a wall switch, contolling 3 switches (is this called a 3 gang?) with dimmer switches. 2 of the switches are 2 way (i.e. controlled on 2 walls) and 1 is one way (just the one switch for the light). Firstly, can anyone let me know where I can get a 3 way dimmer, as they are not easy to find. I have been instructed by the 'Missus' to get the brass Georgian style, but its not easy. Also, will there be a problem with them being 2 way switches. Any help appreciated.
