[my]

I have a 2 gang dimmer switch which I want to change into a 2 gang 2 way switch. The wire is 3 core plus earth, Red, yellow and blue, how do I connect the wire to the correct terminal ports.

Without visualy seeing how the 3 core operates at present with the 2 gang dimmer , it is difficult to advise acurrately , but it is probabel that if as u state all u have is a three core , red , blue and yellow ( Earth sleeved green and yellow connected to earthing point of metal box if present ) , then possibly the red core , could be the feed in to both commons , and the blue and yellow could be two separate switch feeds giving two dimmer outputs to two separate lights . I would advise u get an electrcian in to verify this.
