One of the lights in our house was operated by a dimmer switch that is about twice as wide a normal light switch (14 cm rather than 8 cm). The dimmer unit has recently burned out. The unit must be 30 years old, so not likely to be replaceable. I don't want or need a dimmer switch for the room, so I'd like to put a simple switch plate on the box in the wall. Is it possible to buy a 14 cm wide single switch-plate? I know I could buy a three- or four-gang switch plate, and only connect wires to one of the switches, but I'd rather not, as it would seem a bit odd. I think I'd rather do that, though, than put a new smaller box in the wall and patch up the hole, which would then require painting the whole wall.
How about using a single switch with a 'light switch finger plate' behind it to cover the gap? Any electrical retailer should have them, or Google for loads of links.

If the box in the wall is wider than you need, then get someone to replace it with a normal sized one for you. It's not difficult but around it the wall would probably need plastering and redecorating.
