Bsun Chiikawa - 45g vs. Kailh BCP
An in-depth look at the Bsun Chiikawa - 45g and the Kailh BCP switches—which one is the best fit for you?
Overview
When selecting a mechanical keyboard switch, two popular options that stand out are the Bsun Chiikawa - 45g and the Kailh BCP, both of which fall under the linear switch category. The Bsun Chiikawa - 45g is lauded for its light 45g actuation force, resulting in a bright sound profile and an incredibly responsive typing experience. Users who prioritize a smooth, quick actuation will likely gravitate towards its crisp, high-pitched sound. On the other hand, the Kailh BCP switches present a unique take on the classic Black Cherry Pie design, offering a creamy, bouncy feel that enhances the tactile experience and produces a delightful poppy and clacky sound. While both switches cater to enthusiasts seeking a linear experience, their distinct sound profiles and actuation sensations provide different typing experiences. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your needs.

Housing materials
The Bsun Chiikawa - 45g and the Kailh BCP switches utilize differing materials for their top housings, which significantly influences their auditory profiles and overall user experience. The Chiikawa - 45g features a polycarbonate top housing, known for its stiffness and ability to generate a sharper and more resonant sound. This material is especially beneficial for gamers or typists who value a brighter sound profile, particularly in RGB setups where the translucence of polycarbonate enhances lighting effects. In contrast, the Kailh BCP switches employ a nylon top housing that focuses on a fuller and deeper sound due to nylon’s sound-absorbing properties. The inherent softness of nylon leads to a rounder sound profile, appealing to users who prefer a more subdued auditory experience. This fundamental difference in material composition emphasizes a distinct sound character for both switch types.
When examining the bottom housings, both the Bsun Chiikawa - 45g and the Kailh BCP switches utilize nylon, which leads to a convergence in their sound profiles at this particular level. The nylon bottom housing contributes a deeper and fuller sound because of its sound-absorbing characteristics, creating a more rounded auditory experience. The similarity in the bottom housing materials suggests that users of both switches will experience a comparable sensation when bottoming out, as both nylon constructions provide a damping effect that softens the impact and sound. Thus, both switches can deliver a satisfying tactile feedback, regardless of their contrasting top housing materials.
In conclusion, while the Bsun Chiikawa - 45g and Kailh BCP switches diverge in their top housing materials—resulting in different auditory experiences—their shared nylon bottom housings unify their sound profiles during key presses. This interplay means that even though the top housing influences each switch's sound distinctly, the nylon bottom contributes to creating a fuller sound on bottoming out, ensuring that users can enjoy qualities from both ends. Therefore, users seeking either a brighter or a deeper sound profile might select one over the other based on their top housing choice, but they will still find similarities in the overall experience due to the nylon used in both bottom housings.
Weight
When comparing the Bsun Chiikawa - 45g linear switch and the Kailh BCP linear switch, notable differences in actuation and bottom out forces emerge. The Chiikawa switch features a lighter actuation force of 45 grams and a bottom out force of 51 grams, making it a suitable choice for users who prefer a medium-light typing experience, which can enhance comfort during extended typing sessions or gaming. In contrast, the Kailh BCP switch has a heavier actuation force of 52 grams and a bottom out force of 63.5 grams, appealing to those who enjoy a more substantial push feel while typing. Therefore, while the Chiikawa - 45g lean towards a lighter and more effortless keystroke, the Kailh BCP caters to users who favor a firmer resistance and feedback with every keystroke. Ultimately, if you prioritize a more laid-back keyboard experience, the Chiikawa would be the better option, but if you prefer a heavier typing feel, the Kailh BCP is the way to go.
Travel distance
When comparing the travel distances of the Bsun Chiikawa - 45g linear switch and the Kailh BCP linear switch, we find a subtle difference that may influence user preference. The Chiikawa - 45g features a travel distance of 3.6 mm, while the Kailh BCP has a slightly shorter travel distance of 3.5 mm. This means that the Chiikawa provides a more substantial depth of key travel, which may suit users who appreciate a more pronounced feel when typing or gaming. In contrast, the Kailh BCP caters to those who favor quicker response times due to its shorter travel distance, aligning with a trend seen among gamers who prioritize fast actuation. Overall, while both options can deliver similar results in terms of tactile feedback and performance, the slight variance in travel distance suggests that the Chiikawa is the better choice for those seeking a deeper experience, whereas the BCP may be preferable for those who value speed and responsiveness.

Typing experience
In terms of sound, the Bsun Chiikawa - 45g linear switch is characterized by its bright, high-pitched sound profile, delivering a crisp auditory feedback that enhances the typing experience. In contrast, the Kailh BCP linear switch produces a signature poppy and clacky sound that is somewhat deeper and richer in texture. While both switches may deliver distinct auditory qualities, the specific sound you experience can vary based on factors like the keyboard's construction and the type of keycaps used. Consequently, if you're looking for a brighter experience, the Chiikawa may be preferable, whereas the BCP provides a more robust sound that some users might find satisfying.
Regarding feel, the Chiikawa - 45g offers a notably light actuation force, which contributes to its responsiveness and makes typing feel effortless. Users may find themselves enjoying a light, agile typing experience. On the other hand, the Kailh BCP switch brings a unique creamy, viscous, elastic, and bouncy feel that can provide more tactile reassurance with each keystroke. This distinct sensation allows for a different typing dynamic, making it feel lively and engaging. Therefore, if you favor a light, nimble typing experience, the Chiikawa is an excellent choice, while the BCP excels with its more dynamic tactile feedback.
In conclusion, both the Bsun Chiikawa - 45g and the Kailh BCP linear switches offer unique qualities that cater to different typing preferences. The Chiikawa impresses with its bright sound and lightweight feel, making it ideal for those who favor a light and airy typing experience. Conversely, the BCP provides a deeper sound with a more robust and engaging tactile feel. Ultimately, your choice will hinge on whether you prioritize the lightness and crispness of the Chiikawa or the bounciness and richness of the BCP. Either way, both switches can deliver delightful typing experiences, tailored to your personal preferences.
Conclusion
To wrap up, the decision between the Bsun Chiikawa - 45g linear switch and the Kailh BCP linear switch ultimately comes down to your typing preferences and the kind of experience you seek. If you favor a lighter touch and enjoy the sensation of quick and responsive keys, the Chiikawa switch would be ideal for you. Its 45g actuation force and brighter sound profile create an engaging typing environment that is particularly satisfying for fast typists or gamers who thrive on rapid responsiveness. On the other hand, if you prefer a more substantial feel with a bouncy and elastic response, the Kailh BCP would suit you better. Its medium-heavy 63.5g bottom-out force and its distinctive creamy sound provide a richer auditory and tactile experience that many find more rewarding, especially during prolonged typing sessions. Consider what aspects—be it sound, tactile feedback, or force—matter most to you, and choose accordingly to enhance your overall keyboard experience.
