Needing a quick fix to avoid chasing out walls and ceiling...

Does anyone know of a wireless light switch setup that:

- looks like a normal lightswitch (or fits into an existing one)
- does not have a bulky receiver/transformer at the light, ideally a
device that plugs into a bayonet which the bulb can plug into in turn

The "Easy Switch" system works with 13A sockets or fixed wiring, not
bayonet fittings, but it works very well and might be adaptable for your
purpose:

I have those in use in two rooms, for table lamps. The switch looks
perfectly normal (it's actually one half of a normal two-gang switch,
with the other gang switching the ceiling light in the normal way), and
it works normally, apart from a split-second delay and an audible click
from the receivers (not as loud as X10, though).
