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 and click sound.
As a second generation SKCM/SKCL switch, the upper housing sometimes has slits (colloquially referred to as the “pine” variant).
The stem,
The audible feedback is generated with a leaf spring that is situated on the opposite side of the housing to the contact plate. Alps SKCM White, like all SKCM/SKCL series switches, uses a contact module to register the keypress. This sits in the housing on the side with visible notches.
Additional Information
The switch was likely in production from 19891) to around 1995.
In its earlier form, the switch as a whole is practically indistinguishable from Alps SKCM Blue. 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.
