Thanks for the tip. I really don't know if I have shuttered ones or not. The apartment was renovated recently. Perhaps on 2017. I think that the plugs and some electrical work was a mixture of old and new. Some outlet look really new, but some others seems to be much older.

I really don't know why the shuttered outlets aren't the standard right now.

Probably because they don't really work very well. Extension leads have shuttered sockets, and in my experience they are either too stiff, too loose, or jam open anyway after a while. Not great for a permanent installation.

And anyway if you push something into the socket, the shutter opens - kind of pointless as child protection.

In the UK where they do kind of work the system is different - the earth pin is longer and that opens all three shutters; pushing something into live or neutral just hits a flat plate.

Because they don't work well and tend to break.

I hate them!

We have a bunch of IKEA power bars which we no longer need which are childproof, according to the label. As far as I can tell they are "adultproof" as I cannot manage to plug anything into them.

So yes, highly recommended for childproofing.
