Alps SKCC Cream is a switch in the Alps SKCC series.

Description

The return spring in SKCC Cream (black switchplate) is 10.9 mm long, of 0.22 mm gauge wire, and has nine active turns. This is virtually identical to the spring in grey switchplate Alps SKCC Tall Cream, indicating that they do indeed differ solely in keystem height.

Based on non-scientific keystem-to-keystem testing, SKCC Green appears to be 60 gf, so with the 11:9 free turn ratio of the Cream and Green return springs, the heavier SKCC Cream would be in the region of 70 gf actuation.

Part SKCCBJ0001 has two separated terminal recesses with semicircular ends, just as found in Alps SKCC Green part SKCCBK0001.[1] Normally there is only a single terminal recess, typically with straight ends. This version has a spring in the region of 10.3–10.6 mm long, also of 0.22 mm gauge wire, but only seven active turns.

The following switches were sourced from AliExpress,[3] and are from a batch previously sold on Taobao.[1] They feature a short white switchplate. The photo of the box on Taobao includes only a small fraction of the date stamp, which appears that it may be too faint to read.
