I have 2 dimmer switches in 2 seperate rooms. Dont know why, but all of a sudden lights would not work. The dimmer switches operate 4 spotlights each. The cables at the dimmer switch are as follows. 3 cables with 3 earths into one plastic terminal block, 3 neutrals into one plastic block,and the 3 brown wires. I did not note the original wiring of the dimmers, Yes I know, call me whatever. I replaced the dimmers with 1 gang 1 way switches. The problem now is in one room one of the brown wires is permenent live and I assume the other 2 are switched live. But in the other room there is no live in any of the 3 brown wires. When I turned the switch on with the live wire in both rooms come on, but the room without the live wont come on, on its own. So 1 switch is controlling 2 rooms
