Mark with a ZBritish plugs
I would be mildly annoyed at 110v in easy reach with metal with out an isolation switch.
Having switched outlets wouldn’t make US plugs any safer, at least not in any meaningful way.
The individual switches on UK outlets don’t really add significantly to safety, they’re mostly just a convenience feature, because for an electrical plug/outlet to even be considered safe in the first place, it has to be always safe, whether it’s powered or not. You can’t rely on people switching off unused outlets instead of doing actual safety design.
The main factors that make US plugs less safe than UK ones is the potential for exposed metal contacts with a closed connection to the outlet, the lack of internal fuse and the lack of polarisation, and, particularly in combination with the first point, the tendency of comparatively weak grip strength and portruding design that make it easy for a plug to become (partially) unplugged by accident.
One feature of UK plugs I really like is the built in warding of the live/neutral slots. The ground prong is longer to allow for the mechanism to unlock the hot slot when inserted. It’s essentially a built in childproofing.
Jup, that’s a really good feature. You can get aftermarket child shutters for EU style plugs as well, but they require you to twist the plug before inserting, making them kinda inconvenient, and they have to be specifically installed by parents. Though I don’t think that’s the worst thing in the world. After all, we don’t make any of our other products or home designs toddler safe by default. It’s generally regarded as the parents responsibility to ensure their home is child proof before they get a child.
But the UK version of just having it in every outlet as a hidden feature that you wouldn’t even notice if you don’t know it’s there is definitely the best approach.
(Though it does make low form factor UK plugs almost impossible, because every plug must have a ground prong, if there’s no actual safety need to have one)
AllNewTypeFacePerhaps it could be revised by adding two unearthed Europlug round-pin sockets below the broad pins, though within a recess shaped like the thin European plugs to prevent the connection of earthed plugs, and declaring Europlug to be a British standard for unearthed mains, for use with devices not requiring earthing. Not sure if the geometry would work out, though.
It’s possible to that of course, but I doubt it’s worth it. It also couldn’t be adapted as is, because fuses in each plug are always required t for UK plugs, they aren’t for EU plugs. And if you have to adapt a narrow EU plug to hold a replacable fuse would eat into size savings, require adapting the standard and require entirely new production lines for the modified plugs, so almost certainly simply not worth it.
