Admittedly, that’s pretty awesome. I don’t understand why these sockets with power switches are not common elsewhere.

Because they solve a problem that ~nobody has for ~all their sockets.

Think about it: How many of your sockets do you actually use the switch on? 10%? 5%? Less?

It's smarter to put switches only where they are needed, after all every component in a circuit decreases efficiency and maintainability.

I suppose it’s a use you never realised you needed until you have it. Here are some examples off the top of my head:

  • Sandwich press stays in same place, doesn’t have an on/off button. Just flick switch and no need to unplug when not in use.
  • Power strip for the TV is wedged behind a credenza. Need to power cycle everything plugged into it but would need to move the whole credenza to unplug it. Flick the switch with a stick or arm and it’s done.
  • Using power tools and want to be sure they definitely won’t turn on while adjusting them: flick the switch and no need to unplug.

These things last decades. Even the cheapest ones.

A switch should never reduce efficiency any more than the distance in extra wire (a couple of centimetres at most).

If it does I don't know how you've found one cheaper than an already incredibly cheap product.
