The switches you linked to aren’t going to work very well with most inwall micros because they are “rotary dimming.“
Instead, you’ll generally choose a momentary switch where you “push and hold“ for dimming.
These are all dumb switches which are then combined with one of the Inwall micros we’ve been discussing. (In contrast, the lightwave RF is in “all in one“ device, their switch has the radio built-in so you don’t use the micro with those. You just replace the dumb switch with the smart switch and you’re done. 
)
See the following UK discussion thread:
Help - UK "Momentary" vs "Push" Switch
Which features the following popular line:
In the UK these are often called a “retractive“ switch.
Here’s an ugly one, but it will give you the idea. The longer you press, the brighter the lights will get if they are dimmable.
And here’s some more attractive ones, but there are lots of different ones available. Again, remember these are all just dumb switches which you are going to combine with a smart micro. On some you press at the top, on some you press at the bottom. In the “3 position momentary” style you usually press on the top for on and on the bottom for off. And there are some styles made specifically to use with micros which have two buttons. it’s just an aesthetic choice, they all work the same way as far as the micro is concerned.
If you get a 3 position momentary style, it will work in a manner similar to the lightwave RF all in one switch Where you press and hold the top to make the lights brighter and press and hold the bottom to make the lights dimmer. It’s not a rotary dial that you turn, but most people seem to find it intuitive to use.
This is the lightwaveRF user guide, I think it makes the functionality clear:
