Our kitchen lights are playing up, they're halogen spotlights controlled by a dimmer switch, and one by one they're either refusing to switch on, coming on if the dimmer is halfway on but off when it's fully on, or (weirdest) slowly moving between on and off and on again without touching the switch.
I feel like the first step here is to change to a normal switch - does anyone who knows more than me think not? But the dimmer switch is 18cm wide and it looks like triple conventional switches are much smaller. When I take the switch off the wall, will I be able to take the metal box out, put a smaller one in and use filler or something to fill the gaps? Or is there another way?
