@ZabuzardI tested all 4 scenarios. Dosnt matter ST\MT version is in use and mapping this to the keyboard or the joy. What I got - usually while doing one "push/pulse" we're expecting one step, like in other switches. But this one works differently - his value (reticle depression) depends on how long we doing this push. His logic looks more like an axis. I can push for 3-4 seconds one time and have maximum value.
In the video below I did 5 pulses: 2 short as I could, and 3 more longer
