Kailh BCP vs. Gateron Milky Yellow Pro (KS-3)
An in-depth look at the Kailh BCP and the Gateron Milky Yellow Pro (KS-3) switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the Kailh BCP and Gateron Milky Yellow Pro (KS-3) offer distinct experiences despite both being linear switches. The Kailh BCP elevates the typing experience with its creamy, viscous feel and a unique poppy, clacky sound profile that sets it apart from traditional linear switches. This switch is perfect for those who appreciate a tactile sensation and a sound that adds character to their typing experience without the need for disassembly, making it a convenient choice for customization. On the other hand, the Gateron Milky Yellow Pro (KS-3) embodies the essence of a classic budget switch with its smoothness and low, "thocky" sound that resonates throughout its operation. This switch is designed for versatility, excelling in both gaming and typing situations, making it a favored option among budget-conscious enthusiasts seeking reliability and performance. While both switches cater to distinct preferences and provide unique experiences, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Kailh BCP and the Gateron Milky Yellow Pro (KS-3) both utilize nylon as their housing material—comprising both the top and bottom housings. The shared use of nylon is significant, as it is known for its acoustic properties. This classic material produces a deeper and fuller sound profile while typing, thanks to its relatively softer plastic composition. The design's intrinsic qualities absorb sound effectively, resulting in a more muted, rounded auditory experience. These characteristics are particularly valuable for users seeking a quieter typing environment or a more pleasant acoustic feedback during extended usage.
While both the Kailh BCP and Gateron Milky Yellow Pro feature nylon for both housing components, it is crucial to recognize how the interaction between the top and bottom housings can influence the overall typing experience. The bottom housing impacts the bottom-out sound and feel when the key is fully pressed down, while the top housing primarily affects the sound produced when a key is released. Since both switch types employ the same nylon composition for their housings, the resulting auditory experience should be similarly rich and subdued, regardless of which specific switch is being used.
Ultimately, the similarities in housing material between the Kailh BCP and Gateron Milky Yellow Pro can lead to a comparable typing experience for users. Both switches may produce a similar sound profile due to their common nylon composition, making them excellent options for those who value acoustic performance in mechanical keyboards. Additionally, since both switches will exhibit similar sound dampening qualities, users can expect a comfortable and satisfying typing experience, characterized by the signature deeper tones that nylon provides, regardless of their choice between the two.
Weight
When comparing the Kailh BCP linear switch with an actuation force of 52 grams and a bottom out force of 63.5 grams to the Gateron Milky Yellow Pro (KS-3) linear switch, which has an actuation force of 50 grams and a bottom out force of 62 grams, distinct differences emerge. The BCP switch requires a slightly heavier actuation force and bottom out force, making it better suited for typists who appreciate a more substantial keystroke feel, whereas the Milky Yellow Pro is the lighter option, favored by those looking for less resistance for extended typing or gaming sessions. Although both switches provide a relatively similar typing experience, the BCP's heavier forces may lead to fatigue over long durations, while the Milky Yellow Pro's lighter actuation encourages longer use without straining the fingers. Ultimately, the choice between these two switches depends on personal preference regarding typing pressure and comfort during extended use.
Travel distance
When comparing the travel distances of the Kailh BCP linear switch and the Gateron Milky Yellow Pro (KS-3) linear switch, it’s clear that they differ significantly. The Kailh BCP features a travel distance of 3.5 mm, while the Gateron Milky Yellow Pro has a slightly longer travel distance of 4 mm. This makes the BCP the shorter option, which may appeal to gamers seeking quicker response times and a more rapid actuation. Conversely, the Gateron Milky Yellow Pro, with its longer 4 mm travel distance, offers a more pronounced and hearty typing experience, which some users may prefer for its depth and tactile feedback. Ultimately, the choice between these switches will depend on individual preferences for responsiveness versus depth.

Typing experience
In terms of sound, the Kailh BCP switch produces a signature poppy and clacky sound profile that is quite distinct and lively, making it an engaging choice for typists who enjoy audibly satisfying feedback with each keystroke. In contrast, the Gateron Milky Yellow Pro (KS-3) delivers a deeper, "thocky" sound, characterized by its bassy and low-pitched resonance that provides a rich auditory experience. This thocky sound can offer a more muted and smooth auditory environment, appealing to users who prefer a softer acoustic response while typing. Ultimately, users may find that the choice between clacky and thocky relates to their specific sound preferences, but one should also consider that the overall acoustic experience is influenced by the keyboard's construction and the materials used for the keycaps.
When it comes to feel, the Kailh BCP switch is defined by a creamy, viscous, elastic, and notably bouncy tactile sensation, providing an enjoyable typing experience that many users associate with a plush feedback. In contrast, the Gateron Milky Yellow Pro (KS-3) is celebrated for its buttery smoothness, offering a seamless and effortless keystroke experience that many gamers and typists find appealing. The Milky Yellow also features textured elements, which can introduce subtle friction that might be favored by users who enjoy a tad more resistance. The differing feels of these switches cater to varied preferences, with the BCP appealing to those who favor a soft and springy typing experience, while the Milky Yellow Pro leans towards a smoother, more consistent keystroke.
In conclusion, both the Kailh BCP and Gateron Milky Yellow Pro (KS-3) linear switches offer unique auditory and tactile experiences that cater to different user preferences. The BCP’s poppy clackiness contrasts sharply with the deep thocky sound of the Milky Yellow Pro, while the creamy bounce of the former meets the buttery smoothness of the latter. Ultimately, the choice between these two switches comes down to personal preference, with each offering their own strengths—the BCP for those seeking a vibrant and responsive typing experience, and the Milky Yellow Pro for those who prioritize smoothness and deeper acoustics.
Conclusion
To conclude, the choice between the Kailh BCP linear switch and the Gateron Milky Yellow Pro (KS-3) largely depends on your personal preferences and typing habits. If you favor a typing experience characterized by a creamy, elastic feel combined with a pronounced and engaging auditory feedback, the BCP is likely the better option for you. Its medium-heavy actuation force of 63.5 grams makes it suitable for those who enjoy a more tactile sensation and appreciate the distinctive pop and clack that accompanies each keystroke. On the other hand, if you're looking for a switch that offers smoothness and has a low-pitched, thocky sound profile, the Gateron Milky Yellow Pro (KS-3) stands out as an excellent all-rounder. With a slightly lighter bottom-out force at 62 grams, it provides a buttery typing experience, making it ideal for both gaming and prolonged typing sessions without fatigue. Overall, your specific needs in terms of sound, feel, and actuation force will greatly influence which switch will be the perfect match for your mechanical keyboard setup.
