Quoted from Zennmaster:My next thought is to bend the lever a little more so that it makes contact with the magnet earlier and compresses the switch button with more force, but I also don't want to break anything.
This is probably all it needs. I usually push the actuator down so the first part nearest the pivot is against the switch body. Then while holding it down with one hand slightly bend the actuator at the first bend. But just slightly.
I don't remember if the mist test actually runs the carriage right to left to test those switches or not.
