Alps SKCL Green, or linear Green Alps, is a linear switch in the "complicated" Alps SKCL/SKCM series.

Description

Linear Green Alps switches have an LED recess; the LED occupies the position where the tactile or click leaf should go; typically this recess is left empty. The slider is a different design, and reversible. By the debut of Alps SKCM Brown, the shell and slider were both redesigned, but linear switches kept the 1983-style shell for several years, and it appears that Linear Green Alps also retained the original slider design.

The exact relationship between Linear Green and Yellow Alps remains a mystery. While it's undisputed that Linear Green is older and that Yellow became its replacement, the two overlapped, and the reason for this is unknown. Zenith keyboards have been found with Green/Yellow and Yellow/Green pairings, with one type used for normal keys and the other type used for LED keys. Curiously, this even went as far as top-branded Linear Green Alps in a Zenith ZKB-2R.

As with Alps SKCL Yellow, it appears that the holes for the LED legs were not provided unless the switch was ordered with an LED fitted in the factory.

Linear Green Alps are highly regarded for being an exceptionally smooth linear switch.

Variants

Known variants include:

Early Variant

Examples have been found of early SKCL Green Alps containing differently shaped sliders, top housings and bottom housings compared to typical SKCL Green Alps. Examples have also been found of early Alps SKCL Cream switches with the same unique features.
