There have been warnings in the UK about counterfeits being found
in other parts of Europe (but not as yet in the UK, AFAIK). A picture
in a trade magazine shows one of them opened up. There are no overcurrent
parts inside, and the toggle is just a plain switch.

So, a perverse thought crosses one's mind: would replacing one's
breakers with toggle switches be the equivalent of putting pennies in
fuse sockets in the olden days?

Yes. BTW, they do make them ... switches that replace circuit breakers.
If you need a lot of switches in a circumstance where you don't need the
individual overcurrent protection, and need it in a more compact space
than could be had with a bunch of 2x4 boxes, then this might be the thing.
Imagine if you have a need to individually switch on and off 80 different
7 watt lights. Would you put in 10 sets of 4-gang boxes with duplex switches
in each, or put in an 84-slot panel and 80 switches? The latter might cost
more due to the big box. The latter might not fit so well.
I don't recall if the breakers are cheaper than switches, but perhaps the
economy of scale of production for breakers could do that.

My heat pump has a switch in circuit breaker format in the disconnect
box on the side of the house. A breaker isn't necessary out there, as
the branch is protected in the main panel and nothing else is on it.

How many people ever test the overcurrent aspect, anyway? I'm guessing one
of these must have failed somewhere somehow to have gotten noticed.
