You were down voted for whatever reason. These outlets are complete bullshit. You have your safeties in the electrical cabinet and then you make sure to wire your house according to certain standards. Schuko is leagues ahead of this crap. Modern Schuko sockets will only allow anything to enter, when both prongs are inserted at the same time. If you do happen to short anything, the FI switch (no idea what it’s called in English) will cut the power before anything can happen.
