I'm surprised these sockets you're all posting don't seem to have any safety features like the UK ones do. We have:
- Power switches on pretty much all single phase power sockets
- Insulation on the prongs so by the time you've pushed it far enough in for them to start conducting, you can't touch any bare metal to shock yourself
- Covers which are automatically moved out of the way by the longer earth pin, so to 'accidentally' put something in the socket to shock yourself you'd have to poke something in to the earth socket first... Hard to do accidentally!
I think that's it, but still, that's pretty good.
