I tried two switches in the living-room with all wires removed, just test-fitting the micro-module and the switch and even that would not fit.
There simply is no space to fit the micromodule, the switch and all the wiring running through it. The box is shown in the picture has 7 wires that need to interconnect and also needs to hold the micro-module and the switch. And the reason it fits here is that the plaster on the wall is just thick enough to give that little extra bit of space.
But as I said, I will let it rest for a few days and make-up my mind then.

<br />This is a AW12, also fitted in 40mm deep.

And this also is the box from where my garden gets its juice, so another 3 wires extra and extra "lasdoppen". But it fits.
Make sure the wires are not to long, don't get between the module and the switch (like the 2 blue in your image), cause that wil get you in trouble. It can be done. All first things are hard; the next will be much easier[:)]
