I went and looked at the Mac’s post as you did. I don’t think there is one iota of difference between the two switches for a couple of reasons. 1st the photos of the switch look identical, 2nd the alt part# is the same for both as B5A 11572A. But to be sure I would call Mac’s and ask them what the difference is.
