HMX SU vs. HMX Twilight

Overview

When choosing a mechanical keyboard switch, enthusiasts often find themselves deliberating between options that boast unique characteristics and performance attributes. The HMX SU switch stands out with its full PA12 housing and a T5 stem, delivering a distinctive sound profile that is both subtle and deep, making it a fantastic choice for gamers and typists who value a more immersive auditory experience. In contrast, the HMX Twilight linear switch offers an extended travel distance of 3.85mm, which not only provides a slightly quieter typing experience but also retains the signature clacky sound loved by HMX fans. While both the SU and Twilight switches are linear in design, their differing sound profiles and travel characteristics cater to specific preferences. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

The HMX SU and HMX Twilight switches utilize nylon for both their top and bottom housings, which positions these switches in a similar category concerning their auditory and tactile performance. The key shared attribute is the use of nylon, a softer plastic that inherently absorbs sound rather than amplifying it. This construction leads to a depth and fullness in the sound profile when typing on these switches, characterized by a duller and rounder auditory experience. As both models employ nylon, users can expect consistent acoustics whether they choose the SU or the Twilight, making them appealing options for those seeking a quieter and more subdued typing experience.

Despite the shared housing materials, the SU and Twilight may offer subtle differences in performance due to other factors beyond the housing. While both switches provide the same nylon top and bottom design, the overall assembly, spring tension, and any additional lubricants may vary, potentially influencing how each switch feels when pressed and released. For example, while both share a muted sound signature, the manner in which the nylon interacts with other components can affect the bottom-out feel and the tactile feedback upon key release. Therefore, while the material remains constant, the experience may slightly differ, giving each switch its unique identity.

Ultimately, the distinction lies not in the housing material but in how it interacts with other aspects of the switch's design. The consistent use of nylon across both the HMX SU and Twilight means users will experience the same general sound characteristics, but nuances in performance can be attributed to variations in assembly and internal mechanics. This provides an interesting space for keyboard enthusiasts to explore and contrast both switches, giving them the chance to appreciate which subtleties align best with their personal preferences in typing feel and sound.

Weight

The HMX SU and HMX Twilight linear switches both demonstrate light actuation and bottom out forces, making them suitable for prolonged typing sessions and comfortable gaming. The SU has an actuation force of 45 grams and a bottom out force of 50 grams, while the Twilight features a slightly lighter actuation force of 42 grams, with an identical bottom out force of 50 grams for both switches. This similarity in bottom out force provides users with a consistent tactile experience when bottoming out, regardless of which switch they choose. However, the Twilight switch's lighter actuation force may appeal to those seeking an even easier keystroke activation, potentially enhancing comfort over extended use. In contrast, the SU, although still relatively light, offers a marginally stronger push feel, catering to users who prefer a bit more resistance in their typing experience. Overall, enthusiasts can expect a comparable feel in terms of bottom out force, but the actuation forces position the Twilight as the lighter option and the SU as the heavier choice.

Travel distance

When comparing the travel distances of the HMX SU linear switch and the HMX Twilight linear switch, the SU features a travel distance of 3.6 mm, while the Twilight has a longer travel distance of 3.85 mm. This means that the Twilight switch offers a more substantial depth as you press down on the key, which may appeal to those who prefer a more pronounced feedback in their typing experience. Conversely, the shorter travel distance of the SU switch can provide quicker actuation, making it an appealing choice for gamers seeking rapid responses. Overall, if you prioritize responsiveness, the shorter travel distance of the SU may be more to your liking, while the deeper feel of the Twilight could suit those who enjoy a more traditional typing experience.

Price comparison

Typing experience

In terms of sound, the HMX SU linear switch is characterized by a subtle yet relatively deep sound profile, attributed to its full PA12 housing paired with a T5 stem. This combination generates a sound that is both pleasant and refined, offering a more muted auditory experience. Conversely, the HMX Twilight linear switch, while also maintaining a quieter sound, features an extended travel distance of 3.85mm, which contributes to its slightly more subdued acoustic character. The Twilight retains the signature clacky qualities associated with HMX switches despite being quieter, making it distinct in its own right. However, it’s essential to note that the overall sound produced by these switches can vary based on the keyboard’s design and the type of keycaps used.

When it comes to feel, the HMX SU linear switch offers a smooth and consistent keystroke experience that many typists and gamers appreciate for its predictability and lack of tactile bumps. This makes it suitable for extended typing sessions where comfort is essential. In contrast, the HMX Twilight linear switch, while still providing a linear feel, may offer differences in resistance or travel that can enhance the overall typing experience, particularly with its longer travel distance. This can contribute to a more engaging and possibly more deliberate typing rhythm, depending on personal preferences.

In conclusion, both the HMX SU and HMX Twilight linear switches offer unique qualities and experiences. The SU’s deeper sound and smooth keystroke contrast with the Twilight’s quieter, yet still clacky nature, along with a different feel due to its extended travel distance. If you’re looking for a switch with a refined sound and a smooth feel, the SU could be more appealing. However, if you prefer a slight variation in acoustic profile without sacrificing the linear experience, the Twilight might be the better choice. Ultimately, both switches can provide satisfying outcomes, and your selection will largely depend on your personal preferences in sound and feel.

Conclusion

To conclude, choosing between the HMX SU linear switch and the HMX Twilight linear switch ultimately hinges on your specific typing preferences and the environments in which you'll be using your keyboard. If you're looking for a switch that combines a light bottom-out force with a deeper, more resonant sound profile, the HMX SU may be the better choice for you. Its subtle sound characteristics can provide a pleasant typing experience, especially if you enjoy a tactile feel that doesn’t overwhelm your surroundings. Conversely, if you prioritize a longer travel distance and prefer a quieter sound profile without sacrificing the enjoyable clacky essence of linear switches, the HMX Twilight is an excellent option. Its extended 3.85mm travel not only adds comfort during long typing sessions but also manages to keep noise levels in check. Ultimately, consider how you balance sound and feel in your typing experience—whether you favor a deeper acoustic richness with the SU or a more subdued yet responsive typing experience with the Twilight.
