Why U1?. The Akko Creamy Yellow switch has been a beloved staple in the custom keyboard community since its debut. Over the years, we've received a wealth of user feedback — some prefer the snappier, clackier character of the v3, while others gravitate toward the deeper, more muted sound profile of the v5. At Akko, we've always believed that diversity matters, and that a great switch lineup should reflect the full spectrum of what enthusiasts love.. That's why we created the Akko Creamy Yellow U1 — to bridge the gap between them. It is an entirely new lineup built around our latest understanding of switch smoothness. The Creamy Yellow U1 uses a newly engineered POM blend that retains the material's signature self-lubricating properties while refining the feel even further. The cylindrical stem narrows the sound profile, producing a more focused, low-pitched thock on the downstroke, while the reduced rail contact area paired with the modified POM top housing work together to significantly cut down spring ping.. The result is a switch that sounds more controlled and cohesive across a wider range of builds — making the Akko Creamy Yellow U1 genuinely more versatile.. Name: Creamy Yellow U1. Type: Linear. Operating Force: 45±8g. Total Travel: 3.6±0.4 mm. Pre Travel: 2.0±0.4 mm. Tactile Position: N/A. Tactile Force: N/A
