Alps SKCM Green is a parabolic tactile switch in the second and third generation of the Alps SKCM/SKCL Series.
Characteristics
The switch follows the general characteristics of the SKCM family, consisting of an upper and lower housing, contact module, stem, spring and a leaf spring for generating the tactile event.
SKCM Green straddles two generations, and can therefore be found either as part of the second generation, with slits (“pine” version), or as part of the third generation, without slits (“bamboo” version).
The stem, which is a jade green color, is almost always lubricated and is likely made of POM1). Stem plastic formulation changed between the second and third generations and both look slightly different
The tactile feedback is generated with a leaf spring with a unique shape within the SKCM series, which is similar to that of the leaf used in SKCM Brown.
Alps SKCM Green, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side with notches.
Additional Information
The switch was likely in production from 1990 to 1995. The switch replaced SKCM Brown, which has a similar force curve.
This switch is commonly overpriced and overhyped significantly by scalpers in addition to genuine demand due to its unique tactility and rarity.
Not to be confused with Xiang Min KSB which also has a bright green stem.
