Default No earth to light switch, so sinking a plastic surface back box in a wall?

I've discovered that the wiring to a light switch is in 2 core (i.e.
no earth) so the metal back box was unearthed. Getting an earth to it
would be a royal pain so I've removed the metal back box and plan to
sink a surface box so the back of the switch is in an insulated
enclosure and there's no chance of the screws making contact with a
live wire if a wire broke. What's the opinion of the jury? Any
alternative solutions?


Get some plastic screws instead? If you really are that concerned. But
don't use any type of metal plate switch or dimmer that must be
earthed.


I wanted to solve the problem rather than masking it with plastic screws
that someone might replace in the future.


If you are concerned about what future owners (or whatever) might do, best
get absolutely everything checked out and up to the latest spec. ;-)
