'''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.

The specifications for the [[Alps AKB-3420]] includes the switches. The model number for the switches is not given, but all in all examples found to date, they are SKCC Cream. An older example of this keyboard ca. 1979 specifies the switch lifetime as 3×10⁶ cycles in the product literature, while a later example from ca. 1988 specifies the switch lifetime as 2×10⁷; it is not known whether this large increase was due to greater testing time, or improvements to the design. Based on non-scientific keystem-to-keystem testing, SKCC Green appears to provide 60 gf actuation, 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. Only the "operating force" is officially specified, at 90±25 g, which will be total travel force.

Part SKCCBJ0001 has two separated terminal recesses with semicircular ends, just as found in [[Alps SKCC Green]] part SKCCBK0001.<ref name="Taobao-BJ0001" /> 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.

===SKCCBJ0001===
The following switches were sourced from AliExpress,<ref name="UAE-BJ0001" /> and are from a batch previously sold on Taobao.<ref name="Taobao-BJ0001" /> 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.
