A simple box won't do that, though.

Maybe not, but the box from Argos that I recomended does.

I doubt that Homebase (as you recommended) sell much else.

It's Argos, not homebase. And besides, every switch box I've ever seen
does do it. The only ones that don't are the three into one wired type
connection rigs, not the switch boxes.

And there's really no need to descend to the rather insulting,
condescending last sentence.

Hey, you're the one who asked for an explanation of a very, very basic
scart switching box, not me.
