"You're doing it wrong"
Chthonic confesses: "Only last year did I discover why the lids of things in tubes have a recessed pointy bit built into them." Tell us about the facepalm moment when you realised you were doing something wrong.

Does it make any difference with AC?
I'd thought that as long as you don't miix the earth with either of the others, then it'd be fine. Certainly worked out fine for me in Switzerland with their odd wiring schemes on the older plugs...

Yes, it does
Even though it's AC, the neutral line is tied to earth potential (although over long cable runs, some voltage can build up). The live then alternates + and - from the earth point. Most switches work in single pole mode, i.e. breaking the live line only.
If you swap the live and neutral, then you'll be breaking only the neutral line, so the equipment is effectively still live. It won't work because there's no circuit, but were you to rummage around inside, you'd be liable to get a shock.
