Do the centre keys have the same snap as the edge keys?

The two component adhesive is epoxy I assume?

The center keys are working perfectly! No touch and feel difference to the other keys.

epoxy: See package print in image top left.

When I open a keyboard the sliders always have some sort of grease above the contacts. Do you know if this is important and which kind of material should be used?

That's one small step for a man - one giant leap for mankind.
