Kailh BCP vs. TTC Neptune
An in-depth look at the Kailh BCP and the TTC Neptune switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the Kailh BCP and TTC Neptune offer distinctive experiences tailored to different typing preferences, despite both being linear switches. The Kailh BCP reimagines the classic Black Cherry Pie design with custom-molded switches that deliver a creamy, bouncy feel, enhanced by a signature poppy and clacky sound profile that can invigorate your typing experience. This switch could be ideal for users who appreciate a bit of auditory feedback and a lively tactile sensation. Conversely, the TTC Neptune switch focuses on an innovative internal structure that provides an almost frictionless glide paired with a springy resistance reminiscent of chewy mochi. Its ultralight weight promotes swift and effortless typing, while its muted thocky sound signature caters to those who prefer a more subdued auditory experience. Choosing between the BCP and Neptune hinges on whether you prioritize a colorful acoustics experience or a light, seamless typing action. 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 Kailh BCP and the TTC Neptune switches, we observe distinct differences in their top and bottom housing compositions, which subsequently influence their acoustic profiles. The Kailh BCP features a nylon top housing, a classic material celebrated for its sound-absorbing qualities that yield a deeper and more rounded auditory experience. In contrast, the TTC Neptune utilizes a POM (Polyoxymethylene) top housing, known for delivering a muted yet pleasing sound that also leans toward a deeper profile. While both materials aim to create a fuller soundscape, the softer nylon of the BCP tends to absorb vibrations more effectively, potentially leading to a slightly subdued auditory experience compared to the sharper sound qualities that can emerge from POM.
When we turn our attention to the bottom housings, the differences between these two switches become even more pronounced. The Kailh BCP employs a nylon bottom housing, which promotes consistency with its softer texture and contributes to a cohesive deeper sound profile in conjunction with its top housing. On the other hand, the TTC Neptune opts for a polycarbonate bottom housing, a material that introduces a crisper and sharper auditory experience. The polycarbonate's rigidity allows for an enhanced resonance that may result in a higher-pitched sound when bottoming out the switch. Therefore, while both switches aim to provide satisfying sound profiles, the BCP tends to favor a more uniform and rounded auditory result, while the Neptune introduces a distinct clarity and brightness in its acoustic response.
Ultimately, although the Kailh BCP and TTC Neptune switches utilize different materials for their housing, achieving similar acoustic results is plausible by understanding how each component contributes to the overall sound profile. The nylon in the BCP's top and bottom housings enables a cohesive sound profile characterized by a deeper, rounded tone, while the distinct combination of POM and polycarbonate in the Neptune offers a unique interplay of muffled depth and crisp clarity. Therefore, enthusiasts can choose between these two designs based on their desired auditory experience, knowing how the interplay of materials affects both the feel and sound of the switch when pressed.
Weight
The Kailh BCP linear switch and the TTC Neptune linear switch exhibit distinct differences in both actuation force and bottom out force. The BCP features a higher actuation force of 52 grams, compared to the Neptune's lighter 41 grams. This means that the BCP requires more force to register a keystroke, making it a better option for those who prefer a substantial typing experience and might favor a heavier feel. Conversely, the Neptune, with its lighter actuation force, is more suitable for users who engage in prolonged typing or gaming sessions, as it requires less effort and could lead to less fatigue over time. When it comes to the bottom out force, the BCP also surpasses the Neptune, with values of 63.5 grams versus 50 grams, respectively. This reinforces the notion that the BCP is the heavier switch overall, while the Neptune caters to users who prefer lighter switches for easier keystrokes and longer use.
Travel distance
The Kailh BCP linear switch features a travel distance of 3.5 mm, while the TTC Neptune linear switch has a travel distance of 3.8 mm. This means that the BCP switch has a shorter travel distance compared to the Neptune. The difference of 0.3 mm may seem minor, but it can impact the overall feel and responsiveness of the switch. For gamers looking for quicker response times, the shorter travel distance of the BCP might be more appealing. Conversely, those who prefer a more substantial tactile experience might favor the Neptune due to its longer travel distance, which offers a deeper keypress. Ultimately, the choice between these two switches will depend on individual preferences for depth and responsiveness.

Typing experience
In terms of sound, the Kailh BCP switch provides a signature poppy and clacky audio profile that promotes an engaging typing experience. This lively sound can be quite satisfying for users who enjoy the auditory feedback associated with their keystrokes. In contrast, the TTC Neptune switch delivers a more subdued and thocky sound, characterized by a low-pitched, bass-heavy resonance. While it's described as muted, producing less noise overall, the Neptune’s deep “thud” quality offers a distinct and rich auditory experience that some users may find appealing for its subtlety compared to more traditional clacky switches.
When evaluating feel, the BCP switch is noted for its creamy and elastic sensation, offering a unique bouncy experience akin to typing on a trampoline. This viscous characteristic sets it apart, providing not just physical feedback but also an enjoyable tactile journey. On the other hand, the TTC Neptune switch excels in delivering a frictionless typing experience that is both buttery and springy, akin to the delightful chewiness of mochi. Its ultralight weight and smooth glide facilitate swift typing, while maintaining a mild yet polished feel that is easy on the fingers, making it approachable for all skill levels.
In conclusion, both the Kailh BCP and TTC Neptune switches provide distinct auditory and tactile experiences suited for different preferences. The BCP offers a lively and clacky sound paired with a unique bouncy feel, ideal for those who enjoy active feedback when typing. In contrast, the Neptune offers a more muted and thocky sound with a fluid and polished typing experience, appealing to users who prefer a smoother and subtler touch. Depending on your typing style and sound preferences, both switches can deliver satisfying results, ensuring that there’s a suitable option for everyone in the mechanical keyboard landscape.
Conclusion
To conclude, when choosing between the Kailh BCP linear switch and the TTC Neptune linear switch, consider the specific typing experience that aligns with your preferences. If you favor a more robust and tactile typing experience, the BCP, with its medium-heavy 63.5g bottom-out force and signature poppy, clacky sound profile, is an excellent choice. This switch provides a unique, elastic feel that's both bouncy and satisfying, making it ideal for users who enjoy a more pronounced feedback while typing. On the other hand, if you prioritize a swift and effortless typing experience, the TTC Neptune might be more suitable for you. With a lighter 50g bottom-out force, its frictionless glide and springy feel evoke a smoothness reminiscent of chewy mochi, offering an airy and quiet typing sensation thanks to its muted, thocky sound profile. Choose the BCP for a more immersive and pronounced typing experience, while the Neptune is perfect for those who seek tranquility and ease in their keystrokes. Ultimately, your choice should reflect your personal typing style and the environment in which you plan to use your keyboard.
