Housing materials
The housing materials of the KTT Purple Star and SP-Star Yanyu both offer unique qualities that contribute to the overall sound profile of the switches. The Purple Star utilizes POM for both the top and bottom housing, creating a deep and muted sound profile. On the other hand, the Yanyu combines Polymer nylon and UHMWPE in its blend, resulting in a brighter sound profile that is not particularly sharp. While both materials provide pleasant sounds, the Purple Star's POM gives a deeper and more subdued tone compared to the Yanyu's blend.
In terms of sound impact, the housing materials of the Purple Star and Yanyu switches differ in their effects on key press and release. The bottom housing material, whether POM or the polymer blend, influences the bottom-out sound and feel of the switch when pressed down. On the other hand, the top housing material has more of an impact on the sound when a key is released. This means that the choice of housing material can significantly affect the overall typing experience, with each material contributing to a distinct aspect of the sound profile.
Despite the differences in their housing materials, the KTT Purple Star and SP-Star Yanyu switches both aim to provide a pleasing and unique typing experience. While the Purple Star's POM housing offers a deeper and more muted sound, the Yanyu's polymer blend provides a brighter tone that is still pleasant to the ears. Whether you prefer a deeper or brighter sound profile, both switches showcase how the choice of housing material can make a significant difference in the overall typing feel and sound. Ultimately, choosing between the two switches will come down to personal preference for sound and typing experience.
Weight
The KTT Purple Star linear switch has an actuation force of 43 grams and a bottom out force of 50 grams, making it a lighter option compared to the SP-Star Yanyu linear switch, which has an actuation force of None grams and a bottom out force of 43 grams. The Purple Star requires less force to trigger a keystroke, but exerts more force when bottoming out compared to the Yanyu. Those who prefer a lighter typing experience may lean towards the Purple Star, while those who enjoy a bit more resistance may opt for the Yanyu. Both switches offer a light typing experience overall, so users can expect similar results in terms of weight and feel when using either switch. Ultimately, the decision between these two switches will depend on individual preferences for actuation and bottom out forces.
Travel distance
The KTT Purple Star linear switch has a travel distance of 3.5 mm, while the SP-Star Yanyu linear switch has a travel distance of 4 mm. This means that the Yanyu has a slightly longer travel distance compared to the Purple Star. A 0.5 mm may not seem like much, but it can make a difference in how the switch feels when typing or gaming. Gamers who prefer faster response times may lean towards the Purple Star with its shorter travel distance, while those who enjoy a more substantial key press may prefer the Yanyu. Both switches offer unique experiences, so ultimately, the choice between them comes down to personal preference.
