How does the switch protect children?
Comment on Why do so many UK electrical sockets have an on/off switch next to them?

small child/baby protection.

if it is a small child it is assumed that the joint probability of both turning on the switch and inserting a fork through the holes is roughly the product of probabilities of each (therefore lower than each individually), i.e both events are independent.

Have you tried to stick anything metal into one of these plugs? It is fairly todler proof. I think a 7 year old has the dexterity to defeat it but certainly not a baby.
Manufacturers sell the wall sockets in both switched and unswitched versions so I would say the switch is just there for convenience of the user.
It seems that maybe in the 60s having a switch on the wall was very useful because most electrical devices would have been designed to be switched on or off from its mains power connection (like lamps, hairdryers, vacuum cleaners, electric whisk, etc). I assume the standard was to have a switch as this gave a little extra functionality. Today however many electrical devices have digital electronics that don’t expect to be power cycled and so a switch is not really a feature but an inconvenience (think smart bulb, or Apple TV).

No, hold on a second, let me try and come back.
Joking aside, I agree something like what you explained was probably the original reason. But I have seen some parents praising the switch mechanism for this reason as well but perhaps because they are more used to old European type plugs which does not have the internal security feature of UK plugs

Children love playing with the switch, so I’m not sure how that’s supposed to protect them.

But who will protect the big babies?
