I find this very interesting, even when we are slightly on the edge of the thread. What socket will be the safest?
By my opinion not the Schuko, even when it is pretty safe. The Swiss or new South African looks extremely safe, and polarized. The BS1363 plug with fuse will help to isolate a faulty unit, I see no reason for the switch. On the other hand BS1363 or not exactly small and elegant.

Then we have completely different standards. Powercon looks like a good solution for me :[Linked Image from ]

Maybe to difficult to handle?
