Housing materials

Both the Aflion Blue Sky and the Gateron Box CJ feature polycarbonate top housings, which create a sharper, higher-pitched, and crisper sound profile. This is due to the relatively stiff nature of polycarbonate, which results in a more clear and resonant sound. Additionally, the translucency of polycarbonate makes it ideal for switches that plan to utilize RGB lighting. However, while both switches share this top housing material, it is important to note that the bottom housings differ.

The Blue Sky's nylon bottom housing offers a deeper and fuller sound profile compared to the Box CJ's nylon bottom housing. This is because nylon is a softer plastic that absorbs more sound than harder plastics, resulting in a duller and rounder sound. The use of nylon in the bottom housing of a switch impacts the bottom-out sound and feel when the switch is pressed down, providing a unique typing experience. Despite both switches utilizing nylon for their bottom housing, the different qualities each housing material brings to the switch can be felt when typing.

In summary, the Aflion Blue Sky and the Gateron Box CJ differ in their choice of bottom housing material, with the Blue Sky featuring nylon for a deeper sound profile and the Box CJ offering a rounder sound due to the same material. However, both switches share a polycarbonate top housing which creates a sharp, high-pitched sound profile ideal for switches that plan to utilize RGB lighting. The qualities of each housing material impact the sound and feel of the switches differently when typing, providing users with a choice between a sharper sound profile with the Blue Sky or a rounder sound with the Box CJ.

Weight

The Aflion Blue Sky linear switch and the Gateron Box CJ linear switch both fall into the medium actuation force category, with the Blue Sky requiring 50 grams and the Box CJ needing 45 grams to actuate. However, when it comes to bottom out force, the Blue Sky is slightly heavier at 60 grams compared to the Box CJ's 57 grams, which makes the Box CJ a bit lighter. For those who enjoy a more substantial typing experience, the Blue Sky may be the preferred choice due to its slightly higher bottom out force. On the other hand, those looking for a lighter touch may lean towards the Box CJ. Both switches offer a balanced actuation force that is not too heavy or too light, providing users with a comfortable typing experience.

Travel distance

Both the Aflion Blue Sky linear switch and the Gateron Box CJ linear switch have the same travel distance of 4 mm. This means that when typing on a keyboard with either of these switches, you will experience a similar keypress feel in terms of travel distance. This similarity allows for consistent typing experience across both switches, making it easier for users to adapt to different keyboards equipped with either switch. In terms of travel distance, both switches are on par with each other, offering a standard experience for users who prefer a 4 mm travel distance.

On the other hand, the Gateron Box CJ linear switch offers a clacky sound profile with sharp and percussive characteristics. Both switches fall under the category of neutral sound profiles, making them versatile options for various typing preferences. However, the Box CJ also introduces a chirpy sound element, adding a unique acoustic signature compared to the Blue Sky. Keep in mind that the sound of a switch can also be influenced by factors such as the keyboard board and keycaps used.

When it comes to feel, both the Blue Sky and Box CJ linear switches offer a mild typing experience, providing a gentle and approachable feel for most users. The Blue Sky switch is known for its polished finish, resulting in a smooth and refined typing experience due to either the materials used or factory lubing. Similarly, the Box CJ linear switch also falls under the mild category, offering a comfortable typing feel without overly pronounced characteristics. The Box CJ comes unlubed, allowing users to customize the level of smoothness to their liking, whether opting for a drier, raw expression or adding lubrication for enhanced smoothness.

In conclusion, both the Aflion Blue Sky linear switch and the Gateron Box CJ linear switch offer unique sound and feel qualities that cater to different preferences. While the Blue Sky switch provides a high-pitched sound and polished typing experience, the Box CJ switch delivers a clacky sound with the option for customization through lubrication. Ultimately, the choice between these switches will depend on personal preference for sound profile, typing feel, and customization options. If you prefer a high-pitched sound and smoother finish, the Blue Sky may be the ideal choice, while those seeking a clacky sound and customization potential may lean towards the Box CJ.

Conclusion

In closing, when considering the Aflion Blue Sky linear switch versus the Gateron Box CJ linear switch, it ultimately comes down to personal preference and specific typing needs. If you prioritize a crystal clear linear typing experience with a medium bottom out force and a high-pitched sound profile, the Blue Sky may be the right choice for you. On the other hand, if you are looking for a switch with a swift response, higher-pitched clacks, and a medium-light bottom out force, the Gateron Box CJ might be the better option. Both switches offer smooth push feels, but the Box CJ comes unlubed, allowing for customization to your exacting standards. Whether you prefer a more polished feel or a slightly chirpy sound, both switches cater to different typing preferences. Ultimately, choose the switch that aligns best with your typing style and desired sound profile.
