They’re like that in this apartment we’re renting and I keep seeing them elsewhere. I don’t get it.
To turn them on and off.
Fair enough
the UK power grid is weird. mostly due to echoes of the war. used to be that, to save copper, the entire house and sometimes multiple houses on a street would be wired as one big loop of wire, no fuse box or anything. that’s where the individually fused plugs and switched sockets come from. then, since it turned out to be quite a good idea for safety, they kept doing it.
This is the answer. When all sockets are connected to one big loop, there’s fuses in each socket to prevent a device from screwing with the whole system.
Why are people saying this?
I’ve lived in multiple UK houses and never once seen a socket with a fuse. Are you saying this was change way way back in the day?
All houses have fuse boxes (which then got upgraded to circuit breakers). Not one fuses in sockets. Would be a fucking nightmare to take the socket off and change a fuse.
The fuse is actually in the UK plug (the big brick-like thing with the wire on it), not the socket. But yes, it’s a thing, and most of the rest of the world considers it overkill. Also a lot of cheap junky equipment (ironically the stuff where you’d most want the fuse) omits the fuse in the plug, go figure.
Yea I know, I’ve wired a plug.
Never seen a fuse in a socket though. That comment is completely wrong and yet it’s the most up voted reply.
Never seen a house without a fuse box either.
No fuses in the switch box though, it’s a box of circuits breakers
Yea I know, I said that.
People still call them fuse boxes though.
I am not sure if I mispoke or misread. Apologies for implying ignorance, I just wanted to dump my mind
For safety I guess?
I don’t get how that makes it safer.
So when the dumb person tries to insert a fork in the plug, they don’t die electrocuted.
Have you seen the list of safety features on UK plugs and sockets? The sockets have shutters in them that prevents anything being inserted into the live or neutral sockets unless the (longer) earth pin of a matching plug is inserted first.
Having said that, I agree: seems to be a belt-and-braces approach. No downsides.
And it allows you to cut power to an appliance without having to remove the plug.
So we can turn the power on and off.
Why else would you have a switch next to a power socket?
Most of the places in the world I have been to do without them, or at least did when I was there, so it confused me. But some people have given good explanations now.
Open one up. There’s also a fuse connected to the live wire. The amperage is dependent on the normal draw of the appliance. Just added safety features. Also the live and neutral holes only open up if you put the earth in first (that’s why it’s longer). British plugs are arguably the safest… Unless you leave them prongs up and step on it accidentally. That makes stepping on Lego feel like a shag carpet.
It seems a bit overengineered for little gain compared to good old schuko imo
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.
Allows you to remove power from the plugged in device without unplugging it. This provides convenience to easily and quickly turn things on and off and prevents arcing when unplugging. 240V 13A can arc a bit, particularly if unplugged under load, or on older sockets where the contacts have worn. While a little arcing doesn’t do much damage immediately, over time it will cause pitting and make a high resistance joint that will generate heat.
The switch only disconnects the live terminal, but the neutral terminal should be similar potential to earth (depending on how the building is wired).
Truly the king of plugs and sockets. The plugs are individually fused according to the device needs, ergonomic to use and exciting to stand on.

That’s exactly what I do, because it’s more convenient than unplugging everything.
I live in South Africa, where we had rolling blackouts (called loadshedding) for a few years. It’s easier to switch everything back on when the power comes back than to plug it back into a socket without a switch, especially with my fucked up spine.
The electricity in the place I live was done poorly, so having something plugged in “live” risks a surge or something and then the appliance gets fucked and then everything smells like burnt plastic.
And that’s the best case scenario. Others have had housefires.
Also, the South African plugs aren’t pleasant accidentally to step on. It won’t pierce your foot, but it can still hurt like a motherfucker for a few seconds if you step on it in the wrong way.
Those UK plugs do look a lot more nasty to step on. I shudder at the thought.
I like the EU and US two prong cables ( 🔌?) where the prongs are parallel to the cable, but not the cables with the orthogonal prongs.
