The switches are some sort of custom magnetic reed switches. Probably the only notable part about them is the weighting.
Around 1.5 mm it seems like there's a bit of dirt/dust in the exposed slider mechanism (it's not apparent in all the presses).

Yep, this reed switch is broken. Had to be careful not to cut myself...
And for those that are wondering, yes, it not longer functions correctly.
