Low-profile and analog? There's not a whole lot of benefit to them being analog if the travel distance is too short. Analog triggers on gamepads can be hard enough to really finesse sometimes, and those have much more travel than even ordinary keyboard keys, let alone low-profile ones.
"Depending on which parts of the switch Adomax reduced in the Slim Edition, it may engage the analog input earlier and could thus give you that same 2.2mm (or thereabouts) of analog input, even though the total travel is 3mm to the desktop version’s 4mm."
Tldr, these slim switches could use the same amount of travel for analog input as the full-size desktop version of the switches.
