An in-depth look at the Aflion Blue Sky and the Outemu Purple switches—which one is the best fit for you?

Overview

When comparing the Aflion Blue Sky linear switch to the Outemu Purple tactile switch, there are some key differences to consider. The Blue Sky switch is praised for its crystal clear linear typing experience, offering a smooth push feel and high-pitched sound profile. On the other hand, the Outemu Purple switch does not have any standout features listed but is generally categorized as neutral and mild. If you are looking for a switch with a polished typing experience and a sparkling sound, the Blue Sky may be the way to go. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The Aflion Blue Sky and the Outemu Purple both use polycarbonate for their top housing, resulting in a similar sharp, high-pitched, and crisp sound profile. Polycarbonate's stiffness leads to a clear and resonant sound, making it ideal for switches that prioritize sound quality. Additionally, the translucency of polycarbonate is advantageous for switches intended for RGB lighting, as it allows for vibrant and colorful illumination. While both switches share these characteristics in their top housing material, their differences lie in the bottom housing material.

The Blue Sky features a nylon bottom housing, which contributes to a deeper and fuller sound profile that contrasts with the sharper tone created by the polycarbonate top housing. Nylon's softer composition absorbs more sound, resulting in a duller and rounder sound that provides a unique typing experience. In contrast, the Outemu Purple also utilizes a nylon bottom housing, emphasizing the same qualities of depth and fullness in its sound profile. Despite having different top housing materials, the switches share a commonality in their use of nylon for the bottom housing, showcasing the impact that this material has on the overall typing experience.

The division of housing materials in a switch influences the sound and feel of key presses differently. The qualities of the bottom housing material are more prominent in the bottom-out sound and feel of the switch, while the top housing material has a greater impact on the sound produced when releasing a key. This distribution highlights the importance of selecting housing materials that complement each other to achieve the desired typing experience. Whether it be the Blue Sky's combination of polycarbonate and nylon or the Outemu Purple's utilization of the same materials, understanding the role of each housing material is essential in creating a switch with a balanced and satisfying sound profile.

Weight

Comparing the actuation and bottom out forces of the Aflion Blue Sky linear switch and the Outemu Purple tactile switch, it is clear that both switches have the same actuation force of 50 grams. However, the Blue Sky has a bottom out force of 60 grams, while the Purple switch's bottom out force is not specified. In terms of weight, the Blue Sky is slightly heavier with a medium bottom out force, providing a more substantial typing experience for those who prefer a stronger push feel. On the other hand, the Purple switch's bottom out force remains unknown, making it difficult to determine if it is lighter or heavier than the Blue Sky. Ultimately, the decision between the two switches will depend on individual preference for typing comfort and experience.

Travel distance

The Aflion Blue Sky linear switch and the Outemu Purple tactile switch have the same travel distance of 4mm. This means that when pressing down on a key, both switches will travel the same distance from the top to the bottom. Therefore, in terms of travel distance, both switches will provide a similar typing experience. It is worth noting that a shorter travel distance can result in a faster typing speed, while a longer travel distance may provide a more satisfying tactile feedback. Overall, while both switches have the same travel distance, users may still notice subtle differences in typing feel due to other factors such as actuation force and switch type.
