Housing materials

The housing materials of the Aflion Blue Sky and the Bsun Guyu switches differ in terms of the top housing material used. The Blue Sky features a polycarbonate top housing, which produces a sharper and crisper sound profile due to its relatively stiffer plastic composition. On the other hand, the Guyu uses a POM top housing, resulting in a deeper and more muted sound profile. While the Blue Sky's polycarbonate top housing is ideal for enhancing RGB lighting effects due to its translucency, the Guyu's POM top housing offers a unique sound experience with its deeper tones.

In terms of bottom housing materials, both the Blue Sky and Guyu switches utilize different materials. The Blue Sky comes with a nylon bottom housing, which is known for creating a deeper and fuller sound profile. Nylon, being a softer plastic, absorbs more sound than harder plastics, resulting in a duller and rounder sound. Similarly, the Guyu's POM bottom housing also contributes to a pleasing and unique sound profile with deeper tones and a relatively more muted sound. Despite the difference in materials, both bottom housings offer a satisfying typing experience with their distinct sound qualities.

The combination of different housing materials in the Blue Sky and Guyu switches allows for a unique typing experience. With the top and bottom housings made of different materials, the sound profile of each switch is influenced by a combination of these materials. When pressing down on either switch, the qualities of the bottom housing material will impact the bottom-out sound and feel, while the top housing material will affect the sound when releasing a key. Overall, both the Blue Sky and Guyu switches offer users a variety of sound profiles and typing experiences based on the materials used in their housing construction.

Weight

When comparing the Aflion Blue Sky linear switch and the Bsun Guyu linear switch, the actuation force and bottom out force are the key factors to consider. The Blue Sky has an actuation force of 50 grams and a bottom out force of 60 grams, making it a medium-weight switch. In contrast, the Guyu has an actuation force of 45 grams and a bottom out force of 50 grams, making it a lighter option. For those who prefer a lighter typing experience, the Guyu would be the better choice, allowing for longer typing sessions without fatigue. On the other hand, the Blue Sky provides a more substantial typing experience with slightly heavier forces. Both switches offer similar results in terms of actuation and bottom out forces, but the slight differences cater to different preferences in typing feel. Ultimately, the choice between the two switches depends on whether the user prefers a lighter or heavier typing experience.

Travel distance

The Aflion Blue Sky linear switch has a travel distance of 4 mm, while the Bsun Guyu linear switch has a travel distance of 3.6 mm. The Blue Sky offers a slightly longer travel distance, making it a better choice for those who prefer a bit more depth when typing or gaming. On the other hand, the Guyu provides a slightly shorter travel distance, which may appeal to individuals looking for a quicker response time. Both switches fall within the range of traditional travel distances, with Blue Sky being slightly longer than Guyu. Ultimately, the choice between the two will depend on personal preference and the desired typing or gaming experience.
