10mm extender

Just what I wanted, an extender recessed on one side only. Others are 'helpful' putting a recess on both sides - but are useless when you have a switch with a clip-on cover!! This one can be turned round and switch body sits proud so the cover can be clipped on.

Used for acoustic panels in the studios, looks great, easy to install without de-wiring the sockets. Many thanks
