Repeatability of a cheap micro switch
Measured with my Arduino macro rail, with 1.25 um steps. (x is the position in microsteps.) Red is for turning on, blue - turning off the switch. Both done at a constant speed (2.5 mm/s). Red is a total mess, but blue (switching off) is very accurate (std 2.45 um) except for three wild outliers - which I now believe is a measurement error (due to insufficient lubrication of my rail). I will retest this with a better lubricated rail.
