+**Alps SKCL Green** is a linear switch in the first generation of the Alps SKCM/SKCL Series.
+==== Characteristics ====
+The switch follows the general characteristics of the SKCL family, consisting of an upper and lower housing, [[:terminology:contact_module|contact module]], [[:terminology:stem|stem]], and spring. The upper housing has a hole for an LED, but the bottom housing will only have holes for the LED legs to pass through in switches ordered with an LED.
+As a first generation switch, SKCL Green will always have slits in the upper housing.
+The stem, which is a yellowish green color, is almost always lubricated and is likely made of a nylon blend((tested on SKCM Blue via [[https://wiki.keyboard.institute/lib/exe/fetch.php?media=switch:skcmblueburntest.mp4|burn test]])). Unlike all other stems in the family, first generation SKCL stems do not have a notch on one side and are symmetrical.
+Alps SKCL Green, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side without the LED cutout.
+==== Additional Information ====
+The switch was likely in production from 1983((http://mousefan.telcontar.net/alpsk.htm)) to around 1989((http://mousefan.telcontar.net/alpsk.htm)). The switch was replaced for the second generation by [[switch:alps_skcl_yellow|SKCL Yellow]], with both switches existing side-by-side for a short time.
+Due to its long lifetime, SKCL Green can be found with all of the common long contact module variants (i.e. black, grey and white).
+There was an earlier variant with notches on both sides of the stem and a longer spring positioning pole in the bottom housing. Aside from these changes, it does not appear to be any different to regular SKCL Green in any qualitative way.
+It is possible that the part number for the switch is SKCLAC as this part number is directly adjacent to the part number for [[switch:alps_skcl_cream|SKCL Cream]] which is SKCLAD. "SKCLAC" is listed at several obsolete switch part sellers with no pictures to confirm.
