It all depends on whether your box is recessed in the wall (square or round) and on the socket + switch block (tp 12 socket + switch) or (tp 13 socket + switch). You can't do that, I recessed it into a 3x12 socket but I had a lot of trouble doing it.

Should work. I put a PM Mini (has the same dimensions) behind a Feller EdizioDue small combi (https://www.digitec.ch/de/s1/product/feller-ediziodue-kleinkombi-schema-3-typ-13-lichtschalter-storenschalter-17737922), with a bit of fiddling.

Are very small
Fit without problem
