If I remember correctly, MX Blacks (old ones) are your favourite switch. You'd like these.
They feel, just a bit lighter than MX Blacks, but smooth, holy shit smooth. No lubrication whatsoever.
From my testing, I could probably even set these up as pressure sensors, if I get a controller good enough (the current one doesn't even use all of the switches...).
Pressed (you can see part of the magnet in this picture):
Hall Effect Sensor:
I tried to take the switch more apart but I couldn't find a way to get it apart (very well built), and there wasn't really a need, as the sensor just pulls out. And there's just the casing, slider, spring, and magnet left.
Bug: In Chromium (Linux Google Chrome), I keep getting page crashes, if I use the image tag button in the full editor and then press enter after inserting an image...
