HMX KD200 vs. Bsun Tomcat (Heavy)

An in-depth look at the HMX KD200 and the Bsun Tomcat (Heavy) switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, the HMX KD200 and the Bsun Tomcat (Heavy) both offer unique characteristics that appeal to different types of users. The KD200, a member of the HMX Film switch family, stands out with its pronounced clackiness, making it an ideal choice for those who enjoy an auditory feedback during their typing experience. In contrast, the Bsun Tomcat (Heavy) features Ly stems that provide an exceptionally smooth typing action, creating a silent yet resonant sound profile that appeals to users seeking a more subtle auditory experience. Both switches cater to linear preferences, yet they offer distinct sensations and soundscapes that can influence your typing experience. 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 HMX KD200 and the Bsun Tomcat (Heavy), notable differences emerge, particularly in the top housing. The KD200 features a nylon top housing, which is celebrated for its ability to produce a deeper, fuller sound profile when typing. The inherently softer nature of nylon allows it to absorb sound better than harder plastics, resulting in a duller and rounder auditory experience. Conversely, the Tomcat (Heavy) utilizes a polycarbonate top housing, which encourages a sharper and higher-pitched sound profile. This distinction arises because polycarbonate is a stiffer material, leading to a crisp resonation during keystrokes. Therefore, while the KD200 offers a warm and muted sound, the Tomcat's attribute of clarity could cater better to users seeking a more pronounced auditory feedback during typing.

However, the bottom housing materials of both switches are identical, as both models employ nylon. This commonality results in a similar acoustic quality that is both deeper and fuller, thanks to nylon's sound-absorbing properties. When engaging with either the KD200 or the Tomcat (Heavy), users will notice that the bottom-out sound and feel remains consistent, characterized by that rounded sound that nylon is known to provide. Whether typing on the KD200 or the Tomcat, the user experiences a uniform tactile sensation when pressing down on the switch, enhancing overall typing comfort and satisfaction.

In essence, the duality of different top and bottom housing materials between the HMX KD200 and the Bsun Tomcat (Heavy) results in a nuanced auditory experience. While the KD200’s nylon top promotes a warm sound profile, the Tomcat's polycarbonate top adds clarity. Regardless, users can expect a pronounced and comforting feel with both models due to the nylon bottom housing. If an individual seeks to achieve similar typing results, understanding the interplay between the softer nylon on the bottom and the top's material can guide them toward selecting the switch that best fits their sound and tactile preferences without compromising on the overall typing experience.

Weight

When comparing the HMX KD200 linear switch and the Bsun Tomcat (Heavy) linear switch, there are notable differences in both actuation force and bottom out force. The KD200 features a lighter actuation force of 45 grams and a bottom out force of 50 grams, making it more suitable for users who prefer a softer touch for longer typing sessions or gaming marathons. In contrast, the Tomcat (Heavy) has a stronger actuation force of 55 grams and a bottom out force of 64 grams, delivering a more substantial typing experience for those who enjoy a firmer push feel. Overall, the KD200 is the lighter option while the Tomcat (Heavy) is the heavier switch, catering to different preferences in typing dynamics. While both switches provide distinct tactile experiences, the KD200 will likely appeal to those seeking comfort and endurance, whereas the Tomcat (Heavy) will attract users who favor a more robust feel in their typing experience.

Travel distance

When comparing the travel distances of the HMX KD200 linear switch and the Bsun Tomcat (Heavy) linear switch, we find that the KD200 has a travel distance of 3.5 mm, while the Tomcat (Heavy) measures slightly longer at 3.6 mm. This indicates that the KD200 is the shorter option, making it potentially more appealing for gamers and users who prefer faster response times due to the decreased distance needed to actuate the switch. In contrast, the Tomcat (Heavy), with its longer travel distance, offers a more pronounced tactile experience, which may be preferred by those who enjoy a deeper keypress. Therefore, while both switches provide a linear feel, those seeking quicker actuation might lean towards the KD200, whereas those who appreciate a more substantial depth in their keystrokes might favor the Tomcat (Heavy).

Price comparison

In other words, finding something perfect for you is, in our view, the most important criteria.

Typing experience

In terms of sound, the HMX KD200 linear switch is recognized for being the clackiest option within its family, which suggests a pronounced auditory feedback that can create a lively typing experience. On the other hand, the Bsun Tomcat (Heavy) is characterized by its resonant sound profile, indicating a more hollow and satisfying tone when keys are pressed. Both switches provide distinctive sound qualities, but the clackiness of the KD200 may appeal more to those who enjoy a pronounced auditory interaction, while the resonant nature of the Tomcat (Heavy) might attract users seeking a richer tone. Ultimately, the acoustics will be influenced by additional factors such as keyboard construction and keycap material.

When it comes to feel, the HMX KD200 linear switch is noted for its characteristics aligning with a more traditional linear experience, though specific tactile feedback details are unspecified. Contrarily, the Bsun Tomcat (Heavy) utilizes Ly stems, which are specifically designed to enhance smoothness, promising an exceptionally fluid typing experience. This smoothness can make typing feel effortless and is particularly desirable for users who prioritize a seamless keypress. While both switches fall under the linear category, the focus on enhanced smoothness with the Tomcat (Heavy) suggests it could provide a different level of consistency during use.

In conclusion, the HMX KD200 and Bsun Tomcat (Heavy) linear switches each offer unique qualities that cater to different preferences. The KD200’s clackiness contributes to a more vibrant auditory experience, while the Tomcat (Heavy) delivers a resonant sound profile along with an emphasis on smoothness. Both switches promise satisfying typing experiences but will ultimately deliver distinct auditory and tactile sensations. Therefore, selecting between them will depend on personal priorities regarding sound and feel preferences.

Conclusion

To conclude, your choice between the HMX KD200 and the Bsun Tomcat (Heavy) linear switch ultimately hinges on your preferences for sound, feel, and actuation force. If you enjoy a lighter bottom-out force and prefer the clackier, more resonant sound characteristic of the KD200, this switch will give you an exciting tactile experience that can make typing and gaming more engaging. The minimal resistance also makes it a great choice for those who value speed and swift keystrokes, particularly in fast-paced gaming scenarios or when typing extensively. On the other hand, if you seek a more robust feel with a stronger bottom-out force for a bit more feedback as you type, you should opt for the Tomcat (Heavy). Its higher resistance paired with the smoothness of the Ly stems provides a satisfying typing experience, perfect for long periods of writing or programming. This switch is ideal if you'd like a bit more tactile assurance while benefiting from the quieter, yet resonant sound that the Tomcat offers. Ultimately, consider what aspects matter most to your typing style and environment, and choose accordingly.
