Description
The return spring has been found with 11 and with 12 active turns, both pictured below. The switch is a slightly lighter weight than Alps SKCC Cream, whose spring has been found with 9 active turns for the same approximate length and gauge. SKCC Green's spring has been measured as 10.7 mm long with 0.21 mm gauge wire.
Based on non-scientific keystem-to-keystem testing, SKCC Green appears to be the same weight as General Instrument Series S950 (rated at 60 gf), while it is heaver than RAFI RS 76 C 010 (estimated 50 cN). SKCC Green also appears to share the same return spring as S95010. This would suggest a 60 gf actuation force for Green. From the spring turn ratio (11:9 Cream/Green), this would put Alps SKCC Cream at around 70 cN.
