Aflion Blush vs. Kailh BCP

Overview

When it comes to choosing the right linear mechanical keyboard switch, the Aflion Blush and Kailh BCP stand out as two compelling options, each offering unique characteristics tailored to different typing preferences. The Aflion Blush is celebrated for its smooth and responsive typing experience, thanks to its longer two-stage spring and long pole design, which not only ensures a snappy feel but also produces a distinctively low-pitched, creamy sound profile that many typists find pleasurable. On the other hand, the Kailh BCP reimagines the classic Black Cherry Pie switches with a more modern twist, featuring custom-molded design that simplifies usage by eliminating disassembly challenges. This switch is characterized by its creamy, viscous texture and a bouncy sensation, coupled with a poppy and clacky sound that may appeal to enthusiasts who enjoy a bit more auditory feedback while typing. Each switch offers its advantages, whether you're drawn to the buttery smoothness of the Aflion Blush or the elastic bounce of the Kailh BCP. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

When comparing the housing materials of the Aflion Blush and the Kailh BCP switches, a clear distinction arises from their top housing compositions. The Aflion Blush features a polycarbonate top housing, which contributes to a sharper and crisper sound profile due to the material's stiffness. This characteristic allows for a more defined auditory feedback when the key is released. In contrast, the Kailh BCP utilizes a nylon top housing, which absorbs sound more effectively and results in a deeper, fuller auditory sensation. The inherent softness of nylon produces a sound profile that feels rounder, contrasting with the clarity afforded by polycarbonate. Thus, the top housing of the Aflion Blush is ideal for users seeking a pronounced auditory experience, particularly if they plan on utilizing RGB lighting due to its translucency, while the Kailh BCP caters to those who prefer a more muted acoustic response.

However, both switches feature nylon in their bottom housing, creating a shared sound characteristic that contributes significantly to the overall acoustic signature. The nylon bottom housing in both the Aflion Blush and Kailh BCP serves to absorb sound, yielding a deeper and fuller sound profile irrespective of the differences noted in their top housings. This dual use of nylon allows for a consistent bottom-out feel and sound when pressing down on the switches; hence, the muted and round auditory feedback is a shared quality. Users can expect a similar interaction with both switches in terms of how the bottom housing affects the overall experience during key presses, integrating the softer characteristics provided by nylon.

In summary, while the Aflion Blush and Kailh BCP switches differentiate themselves through their top housing materials—polycarbonate versus nylon, respectively—their similarities emerge through the use of nylon in the bottom housing, bridging the gap between the two. For those seeking a bright and lively sound, the Aflion Blush's polycarbonate top offers a unique experience; meanwhile, the Kailh BCP’s nylon top appeals more to users who favor a classic and subdued auditory profile. Ultimately, the combined effect of both the top and bottom housings significantly impacts how the switches sound and feel, allowing enthusiasts to select according to their preferences while still recognizing the shared essence imparted by the common use of nylon in the bottom portion of both switches.

Weight

When comparing the actuation and bottom out forces of the Aflion Blush linear switch and the Kailh BCP linear switch, some notable differences emerge. The Aflion Blush has an unspecified actuation force, making it challenging to provide a direct comparison; however, its bottom out force is measured at 58 grams, which is classified as medium. In contrast, the Kailh BCP features an actuation force of 52 grams, indicating a relatively lighter feel, along with a bottom out force of 63.5 grams, categorized as medium-heavy. This suggests that the BCP switch necessitates a slightly stronger push to actuate and offers a firmer bottom-out experience, making it a better choice for those who prefer a more substantial typing feel. Given that the BCP has a defined actuation force and the Blush does not, users seeking a lighter switch will find the BCP preferable, while those who appreciate a heavier touch might lean towards the Blush, depending on the unknown actuation force. Overall, the Aflion Blush is likely the heavier option when considering bottom out forces, while the Kailh BCP is lighter in terms of actuation force.

Travel distance

When comparing the travel distances of the Aflion Blush linear switch and the Kailh BCP linear switch, we find that the Blush measures 3.3 mm, while the BCP has a slightly longer travel distance of 3.5 mm. This means that the Blush switch offers a shorter travel distance, which may appeal to gamers seeking quicker response times, while the BCP, with its longer travel distance, may provide a more substantial feel for users who prefer a deeper actuation. In summary, if responsiveness is your priority, the Aflion Blush is the more suitable option; however, if you favor a more pronounced depth, the Kailh BCP might be your best bet.

Typing experience

In terms of sound, the Aflion Blush linear switch is characterized by its low-pitched, poppy sound signature, lending a bass-heavy and mellow tone that can be pleasing to the ear during typing sessions. Meanwhile, the Kailh BCP linear switch shares a similar poppy sound profile, albeit described more as clacky. While both switches can deliver satisfying auditory feedback, the nuances in their sound may vary slightly based on personal preference and the specific keyboard setup, including the choice of board and keycaps, which can greatly influence the final acoustic experience.

When it comes to feel, the Blush stands out for its impressively smooth and buttery typing experience, attributed to its longer, two-stage spring that allows for a creamy, silky sensation with minimal resistance throughout the keystroke. This creates an effortless typing experience that glides smoothly beneath the fingers. In contrast, while there is no specific description available for the feel of the BCP, it is commonly understood that Kailh's rendition retains a quality that emphasizes a tactile fluidity, likely maintaining a similar level of comfort and responsiveness to suit avid typists.

Overall, both the Aflion Blush and Kailh BCP linear switches cater well to users seeking a satisfying typing experience. The Blush excels with its creamy, silky smooth feel and low-pitched, poppy sound, making it ideal for those who appreciate a buttery keystroke. The BCP, while not explicitly detailed in its feel, likely aligns closely in delivering a poppy auditory experience and a pleasant tactile sensation, ensuring that users of either switch will enjoy a similar satisfaction in their typing sessions. Ultimately, your choice between the two may depend on your particular sound preference and the subtle differences in how they align with your typing style.

Conclusion

To conclude, choosing between the Aflion Blush and the Kailh BCP linear switches ultimately depends on your personal preferences and typing style. If you lean towards a smooth and buttery experience with a lower bottom out force, making quick typing feel satisfying with a unique poppy sound, the Blush switch could be your ideal pick. Its creamy and silky feel allows for fluid keystrokes that are perfect for extensive typing sessions or gaming marathons. On the other hand, if you prefer a slightly heavier feedback that delivers a bouncy and elastic sensation, the Kailh BCP is worth considering. Its medium-heavy actuation force contributes to a robust typing experience, and the custom-molded design means you won’t have to deal with disassembly hassles. The BCP's clacky sound profile complements its unique feel, making it ideal for those who enjoy a more tactile auditory experience with each keystroke. In summary, your decision should be guided by whether you prioritize a smoother, lighter touch versus a more resounding and bouncy feel.
