HMX SU vs. HMX Swift

Overview

When it comes to choosing between the HMX SU and HMX Swift mechanical keyboard switches, both linear options offer unique characteristics that cater to different preferences. The HMX SU switch is celebrated for its full PA12 housing and a T5 stem, delivering a subtly deep sound profile that appeals to users who enjoy a more intimate typing experience. On the other hand, the HMX Swift distinguishes itself with its robust, full nylon housing and a silky smooth feel, making each keystroke feel light and effortless—and its 42g actuation force offers a delightful "clacky" quality that many gamers and typists find engaging. While the SU is perfect for those who value a deeper sound and solid build, the Swift excels in providing a bouncier, creamier touch for users who like a lively 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

The comparisons between the HMX SU and HMX Swift housing materials reveal a significant uniformity in their construction, as both models feature nylon for both the top and bottom housings. This choice of material is consistent across both switches, with nylon being recognized as a classic housing material in the keyboard switch landscape. The benefits of using nylon include a deeper and fuller sound profile during typation, attributed mainly to its softer composition that allows it to absorb more sound than harder plastics. This shared characteristic means that users of either model will enjoy similar auditory experiences, marked by a duller and rounder sound signature that many typing enthusiasts appreciate.

In considering the properties of the nylon materials used in both models, it is evident that users can expect parallel tactile and acoustic experiences. Both the top and bottom housings of the HMX SU and HMX Swift are constructed from the same nylon, which reinforces the overall sound profile whether the key is pressed down or released. Since the sound generated while bottoming out is influenced primarily by the bottom housing and the sound while releasing the key by the top housing, the uniformity in material ensures that the intended sound qualities are maintained across both actions. Thus, whether using the SU or the Swift, typists will experience consistent feedback and auditory responses.

Despite the shared use of nylon for both the top and bottom housings in the HMX SU and HMX Swift, it’s worth acknowledging that if there were a difference in the materials, the sound and feel during typing could be affected in more nuanced ways. Each housing would contribute distinctly to the overall output, with the bottom housing impacting the bottom-out sound and feel more significantly, while the top housing would shape the release sound. However, given the identical composition for both models, enthusiasts can confidently expect that they will receive a similar typing performance and sound profile, making the choice between the two largely a matter of aesthetic or functional preferences rather than material-driven differences.

Weight

The HMX SU and HMX Swift linear switches both exhibit light actuation and bottom out forces, making them suitable for users who prefer a lighter typing experience. The SU has an actuation force of 45 grams, while the Swift provides a slightly lighter actuation force at 42 grams. Both switches share the same bottom out force of 50 grams, which means that once fully pressed, they provide a comparable resistance regardless of the actuation force. The lighter actuation of the Swift may be more appealing to typists looking for easier key presses during extended use, like during long workdays or gaming sessions. In contrast, the SU, being slightly heavier in actuation force, caters to those who enjoy a bit more resistance and a more substantial feel during their typing experience. Overall, while both switches are conducive to comfortable usage, the choice largely depends on personal preference for the tactile sensation of the actuation force.

Travel distance

The HMX SU linear switch features a travel distance of 3.6 mm, while the HMX Swift linear switch has a slightly longer travel distance of 3.9 mm. This means that when pressed, the SU travels a total distance that is 0.3 mm shorter than that of the Swift. For gamers or users who prioritize quick response times, the shorter travel distance of the SU may be more appealing, as it allows for faster actuation. Conversely, those who appreciate a more substantial feel when typing may prefer the Swift, which offers a deeper experience with its longer travel distance. In summary, the SU offers a more responsive option, while the Swift provides a more traditional and hearty depth, reflecting the different preferences among users.

Price comparison

Typing experience

When it comes to sound, the HMX SU linear switch is characterized by a subtle yet relatively deep acoustic profile, which results in a more muted typing experience. This sound is often perceived as warm and less intrusive, making it suitable for quiet environments or those who prefer a less pronounced audio feedback during typing. On the other hand, the HMX Swift linear switch features a deeper sound profile as well, attributed to its full nylon housing. This contributes to what many describe as a more resonant and refined auditory experience, allowing for a richer and fuller sound with a notable dimension, albeit the Swift is typically associated with a clackier and sharper auditory signature. Overall, while both switches offer appealing sound profiles, the SU is more subdued, whereas the Swift's sound is brighter and more pronounced, making it suitable for different preferences depending on the typing context.

In terms of feel, the HMX SU linear switch does not have a specific description provided, leaving its tactile feedback somewhat ambiguous. In contrast, the HMX Swift linear switch excels with a multitude of subjective experiences due to its design. It boasts an easy-to-press mechanism, characterized by a gentle resistance that makes typing comfortable and reduces finger fatigue. The switch feels feathery, requiring minimal force to actuate, which is perfect for long typing sessions. Additionally, it offers a bouncy quality that provides satisfying spring-like feedback with every keystroke. Many will find it creamy in sensation, delivering a smooth and buttery experience that enhances overall typing fluidity. Consequently, those who prioritize a softer and more responsive feel will likely favor the Swift, enjoying its combination of ease and satisfyingly tactile feedback.

In conclusion, while both switches share a commitment to providing a linear typing experience, they diverge significantly in their subjective qualities. The HMX SU linear switch presents a subtle, deep sound and an indistinct tactile response, making it perfect for environments where quiet operation is favored. In contrast, the HMX Swift linear switch stands out with a more pronounced auditory profile coupled with an array of positive tactile sensations, including easy actuation, buoyancy, and a creamy smoothness. Thus, while either choice can enhance a typing experience, the decision comes down to the importance of sound and feel in day-to-day usage.

Conclusion

To conclude, choosing between the HMX SU and the HMX Swift linear switches ultimately depends on your preferences for tactile feedback and sound profile. If you prefer a deeper, more subtle sound with a full PA12 housing and a slightly richer typing experience, the SU might be the better option for you. Its smoothness can offer a satisfying feel during prolonged use, making it a strong choice for those who enjoy a quieter, yet refined, typing environment. On the other hand, if you lean towards a more vibrant audio experience paired with a lighter touch, the Swift linear switch shines with its clacky sound and silky smoothness, offering an exceptionally easy-to-press action that can greatly enhance your typing comfort and speed. The 42g actuation force of the Swift not only reduces finger fatigue but also provides a lively, bouncy feel that can be particularly enjoyable for gamers and fast typists. In summary, consider what aspects you value most in your keyboard experience: the deep nuances of the SU or the bright, responsive nature of the Swift, and you will be well on your way to selecting the perfect switch for your needs.
