Is the bottom (PCB) half of the switch the same for both switches?
If this is true, and you like (black) linear but you find it's too stiff, you could take the spring from the brown and it will be soft-linear.
If you like (brown) tactile, but you find it's too soft, you could take the spring from the black and it will be stiff-tactile.
Or is it not that simple? Thanks.
