That is if the gridswitchis not in the same room, I assume you mean.

Yes, and sufficiently nearby to be possible to swear in time at the w*nker
about to electrocute you.

You could possibly get round this by suggesting that the unswitched
socket provides DP isolation instead of the grid switch,

By removing the plug?

Indeed. Also, many sockets now incorporate DP switching, so I suspect that
such a modern switched socket would be appropriate too.
