NotesThese are progressive rate, with a pretravel of ~2.4 mm, and total travel of 3.0 mm. At the pretravel point, the force increases significantly.
Force to pretravel is fairly light, maybe 50 cN; these are not heavy but they are distinctly heavier than the clear version.
Contact resistance is high, somewhere in the region of 400–800 Ω.
One is definitely destroyed; a second may also be (assuming so for now). One is intact and in visibly good condition, but is open circuit.
Part number SKPAAB exists, which may cover these switches.
