 The switch was likely in production from 1985((https://patents.google.com/patent/US4642433)) to around 1989. It has been seen with every variation of contact module used in the mainline SKCL/SKCM series, from the original tall black contact module((NEC PC8801)) to the short white contact module more commonly associated with the second generation of SKCM/SKCL switches((https://geekhack.org/index.php?topic=86189.0)). However, tall grey contact modules are most common. Variations in stem dye lots were commonplace and should not be taken as evidence of some instance of the switch being better than another.
-The leaf spring that generates the tactile and audible events had at least one revision. The original form of this leaf spring had smaller lateral tabs and no bend at the bottom, as well as appearing visually to be made from a different material. The later form of this leaf spring is indistinguishable from that found in the successor, [[switch:alps_skcm_white|Alps SKCM White]].
+The leaf spring that generates the tactile and audible events had at least one revision. The original form of this leaf spring had smaller lateral tabs and no bend at the bottom, as well as appearing visually to be made from a different material. This form is similar but not identical to the leaf found in [[:switch:alps_skcm_amber|Alps SKCM Amber]]. The later form of this leaf spring is indistinguishable from that found in the successor, [[switch:alps_skcm_white|Alps SKCM White]].
 In its later form, the switch as a whole is practically indistinguishable from Alps SKCM White. Indeed, there is significant overlap between the two switches with some early Alps SKCM White being factory lubed, which makes them completely identical to the latest Alps SKCM Blue.
 There is also a heavier version of this switch, only observed so far in NEC PC-8801 keyboards with an extremely high weighting, marked with black marker on the stem. Given it does not appear to have been seen anywhere else, this is likely a customized switch and not part of the series proper.

+There is a purported "pale blue" variant with a very slightly different stem, however no disassembled pictures of the switch have ever been provided and it is impossible to substantiate any potential difference to the rest of the line, or indeed any Alps progeny.
