Here is a pic of an Alps switch for reference:
This is from my SMK 85 as we all can see. I went to snap a pic of the orange sliders which were made one year later than the Apple Desktop Bus above, and I noticed they look nearly identical to the ones in the SMK, but they do not have the Alps logo on the top.
These are the orange sliders that came in another of my three Apple Desktop Bus Keyboards. These feel a little lighter to the touch than the blacks I am typing on right now, and they are not quite as noisey. They do click, but it isn't very profound anymore. 20 years of use will do that though.
This keyboard is pretty dirty. I didn't clean it up yet since this is the one with the dead switch under the F key. If I end up fixing it, then I'll clean it up, but for now I just use it as a reference. The Alps blacks are better than the oranges.
