They’re like that in this apartment we’re renting and I keep seeing them elsewhere. I don’t get it.

    All modern wiring in the UK has every socket in the building connected via RCD (the more common name for GFCI outside America), but they’re usually in the main fusebox/consumer unit rather than individually per socket. These are just normal on/off switches for the convenience of being able to turn things on and off.
