Housing materials
The housing materials of the Aflion Thunder Shadow and the SP-Star Yanyu offer unique characteristics that contribute to the overall sound profile of the switches. The Thunder Shadow's polycarbonate top housing provides a sharper and crisper sound profile, thanks to its stiffness, making it ideal for users who prefer a more distinct typing experience. In contrast, the Yanyu's Polymer nylon and UHMWPE blend top housing offers a pleasant and bright sound profile, creating a different typing sensation for users who prefer a softer and smoother feel.
When it comes to the bottom housings, the Thunder Shadow's nylon material delivers a deeper and fuller sound profile due to its softness and sound absorption properties. This results in a duller and rounder sound compared to the top housing, providing a more muffled typing experience. On the other hand, the Yanyu's unique blend of Polymer nylon and UHMWPE for the bottom housing offers a pleasant and bright sound profile, adding a different dimension to the typing feel that may appeal to users looking for a more balanced sound profile overall.
While both switches have different top and bottom housing materials, the qualities of each material are distributed between the top and bottom of the switch, impacting the typing experience in distinct ways. The bottom housing plays a significant role in the bottom-out sound and feel, while the top housing affects the sound when releasing a key. Despite these differences, users can expect similar results in terms of sound quality and feel, as both switches aim to provide a unique and enjoyable typing experience with their respective housing materials.
Weight
When comparing the actuation force and bottom out force of the Aflion Thunder Shadow tactile switch and the SP-Star Yanyu linear switch, it is evident that the Thunder Shadow has a medium-heavy bottom out force of 63.5 grams, while the Yanyu has a lighter bottom out force of 43 grams. The actuation force of both switches is not specified. The difference in bottom out force indicates that the Yanyu switch would provide a lighter typing experience compared to the Thunder Shadow. Some users may prefer the lighter bottom out force of the Yanyu for extended typing or gaming sessions, while others may prefer the heavier bottom out force of the Thunder Shadow for a more substantial typing experience. Ultimately, the choice between the two switches will depend on individual preferences for typing feel and force requirements.
Travel distance
The Thunder Shadow tactile switch has a travel distance of 3.5mm, while the SP-Star Yanyu linear switch has a travel distance of 4mm. This means that the Yanyu has a slightly longer travel distance compared to the Thunder Shadow. In terms of preference, gamers may lean towards the Thunder Shadow for its shorter travel distance which can lead to faster response times. On the other hand, those who prefer a more satisfying depth when typing may opt for the Yanyu with its longer travel distance. Overall, both switches offer unique travel distances that cater to different preferences, allowing users to choose based on their specific needs and comfort levels.
