“Water nurtures all things” is the slogan of this switch, featuring a milky-white top housing paired with a light aqua-blue bottom housing that evokes a sense of “flowing water” akin to the overall theme of the Ripple Switch in terms of sound and visuals. Specifications: Upper Housing: Nylon Stem: POM Bottom Housing: Nylon Spring: SUS 20mm Actuation Force: 46gf Bottom-out Force: 58gf Actuation Travel: 1.8mm Total Travel: 3.5mm Mold Provider: SWK The 20mm, 58g single-stage spring complements the 3.5mm total travel, ensuring it’s neither too stiff nor too light, making it an excellent daily driver with a comfortable range. Material: Considering the damping characteristic of the semi-silent structure, POK material was chosen for the stem instead of POM due to its higher impact strength and better toughness. Furthermore, a modified formula patented by Xiaoxing in South Korea, incorporating a certain proportion of organic silicon elastomer, is used to improve smoothness. Sampling and Modification: SWK has invested significant time and effort in R&D, from selecting mold steel and plastic materials to lubricants. They participated in the process, and we express our gratitude for SWK's cooperation!We have conducted numerous sample tests and material adjustments with SWK, trying almost all available material combinations to select the best one. This switch meets excellent standards: smooth feel, moderate pressure, and noticeable bottom-out feedback without being too harsh. We must mention SWK's deep understanding of materials, which has greatly benefited us.The semi-silent design (hollowing out the upper part of the guide rail where it contacts the upper housing) reduces contact area, effectively solving the problem of stem rebound noise against the upper housing.The factory lubrication of this switch can meet the needs of most players (including those accustomed to hand lubrication). We continuously adjusted and tested during the sampling period, lubricating only a small amount of the stems and guide rails. This ensured that the final result had almost no extraneous noise when pressed and installed, ensuring a smooth and quiet experience.
