ok I've learned that when you replace (or re-calibrate) the switch, you -must- pull the red part all the way out, insert and then pull it all the way back in to secure.
The trick it to pull all the way out and don't touch the switches' tip, just let the clutch slowly to calibrate it and you are done. If you press the tip all the way in then calibration is wrong and you must pull it out again.
