I expected Technology Connections or ElectroBOOM, was not disappointed.

One teaches what to do, the other teaches what not to do.

ElectroBOOM keeps me alive sometimes, and Technology Connections told me how to properly use a dishwasher.

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.

[–] donuts 59 points 5 days ago

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.

[–] [email protected] 41 points 5 days ago

This isn't strictly true. Most houses built between WWII and the '90s were built with sockets that didn't have switches on them. It was only later safety regulations / suggestions that made the switches preferable.

Where I live was built in the late '80s right before switched sockets became more common. All the original sockets have no switch. Some in the kitchen have switches, but it's clear these were added at a later date.

I'm not sure of the exact rulings and where and when a socket must have a switch, but you can still find switchless sockets for sale at the sorts of retailers who sell those sorts of things, so there are definitely places where those sockets are still allowed.

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.

So we can turn the power on and off.

Why else would you have a switch next to a power socket?

This is virtually standard in Australia

[–] DesertHermit 12 points 4 days ago

Depending on who built the house, it's the standard for a "good" house in Ghana, Nigeria, Zambia and I think Kenya.

[–] [email protected] 12 points 4 days ago

It is standard in NZ

UK household electricity is pretty spicy compared to many other places - it has more safety features as a result. (3 pinned fused plug, socket switches etc)

[–] [email protected] 26 points 4 days ago

Isn't it just 230v 50 Hz like most of the world?

Apparently around 65-70 % of the world population (with access to electricity) has 230v 50 Hz.

How is it more "spicy" than anywhere else in Europe?

And Japan, and Canada, and Mexico, and the majority of South America, and a handful of countries in Africa and the Middle East.

The rest of Europe has 220V as well and they don't have switches on their outlets.

I like them, personally. You don't have to use them but they are sometimes handy. I just spent 30 seconds feeling around a TV to turn it off only to discover it doesn't have buttons. Killed it at the wall.

It's not a deal breaker, in any case. The weird foreign convention I would like to shame is doors that require a key to open from the inside.

As any cautious parent could tell you, these are helpful when the toddler starts sticking things in places where they don't belong. Such as metal cutlery. In the power sockets.

[–] [email protected] 35 points 4 days ago (4 children)

Don't toddlers start pressing buttons even earlier? Not sure this alone could protect them

[–] [email protected] 12 points 4 days ago

This isn't the reason.

The switch is more likely to attract a toddlers attention. Some have little red lights even. It would be false sense of security at best. You can get those plastic blank plugs to stop your kid putting a fork in there.

The switch is so, if you kid is being electrocuted by putting their fork in the toaster, you can turn it off at the wall without having to touch the electrified kid.

[–] gAlienLifeform 33 points 5 days ago (15 children)

Kind of off topic, but I've just gotta add that the safety shutters over the positive and negative terminals that only open when the ground pin (which is longer than the others on the plug) is inserted up top is brilliant, it basically makes short circuiting impossible. Electrical outlet design is one of the few things I'll concede the UK does better than the rest of the world.

Great for turning off a device or several devices without having to unplug (e.g. if the sockets are behind a bookcase, this is much more convenient). Not a super common need but when it saves moving furniture it helps. Given that UK switches are tougher to plug in and unplug than most (due to safety features), I prefer using a switch. Also, the switches are cheap and give more options, so may as well!

I rely on one for a light where the switch broke and wasn't easily replaceable, so being able to fall back on the mains switch meant I can keep using the light.

I like the integration of the switch, should be standard. I use many switch plug-ins just to avoid stand-by consumption (it really adds up over the year) and to avoid high pitch humming on some devices.

YSK: there's also remote controls for these switches, very handy 1000083879

Safety, easier to switch things off without unplugging them. Why not have one if it's more convenient? Not all of them have switches though.
