Hi, I'm a complete novice so apolgise in advance for my stupidity, just don't want to risk anything with electrics involved!
I have recently had a bedroom re-plastered, and decided to get new switch for light, replacing the old plastic one with a new metal dimmer switch. Unscrewing from the wall, I've discovered two wires attached to switch - a red and a black - but in the instructions with the dimmer it is looking for three wires. If it helps I think it is the earth that is missing. Help what do I need to do?
