So in the below pics of a keyboards profile side on:
1: I don't mind if the keyboard slopes downwards or remains totally flat in line with the desk, so long as the overall angle that the keys are presented all match. i.e. Their faces are all at the same angle relative to the board underneath.
2: Example of a concave profile where the keys angle change from top row to bottom row to attempt to be "ergonomic" for the user. The shape of this profile I am calling concave in that it attempts to arc the keys inwards towards the middle row.
3: Some keyboards actually do this. The one I am typing on at home right now as a backup to the one I broke does this. It's even worse than number 2 above. So it's again an arc/curved/concave shaped profile, accept the last row falls away on an opposite curve. All in the name of being "ergonomic".
The above examples are slightly exagerated. The QPAD might be more subtle. What I was getting at, is that I wonder if the actual switches underneath the keys follow this profile shape in the actual angle they are soldered to the board underneath, or if it's simply the keys that are shaped in this way and they all slot onto a "normal" downward profile shape as in example number 1.
Does this explain what I mean?
EDIT: So basically with the QPAD, if it matches the shape of profile 2 below (middle pic), when you take the keys off and look at the bare switches, do they follow the same profile? i.e. The naked switches, are they angled in this way too, or like in example number 1, all parrellel to the board underneath at the same angle?
