I have a light switch where the plaster board around the edges of the face plate have broken away.
I was thinking of using some kind of filler like Polycell to fill the holes but I'm not really sure how I would go about it. Is it simply a case of mixing the filler quite thick and applying to the holes?
I don't know if this is relevant but the back plate behind the light switch isn't attached to the wall in anyway. The back plate seems to be stay in place by screwing in the light switch.

Pick up a small bucket of an all purpose patch likeDap Flexall All Purpose Filler. The all purpose stuff is a little thicker than typical joint compound, so it makes filling a bit easier.
Remove the switch cover.
Using a taping knife, fill in the holes by pushing the compound into the hole and drawing the knife away from the hole.
Like so...
Repeat for each hole.
Wait for patch to dry.
Sand, Prime, Paint, Reattach the face plate.
If you find the holes are too big, and the compound is just falling through the hole. You'll have to get a wall repair patch kit, to fill the holes before covering them with compound/plaster. Follow the directions on the patch kit.
