HMX FJ400 vs. HMX Swift
An in-depth look at the HMX FJ400 and the HMX Swift switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the HMX FJ400 and HMX Swift linear switches offer distinct features that cater to different preferences. The FJ400 serves as a reliable middle ground within the HMX Film switch lineup, delivering a well-balanced sound profile that appeals to users seeking a versatile typing experience without extreme characteristics. On the other hand, the HMX Swift is designed for those who appreciate a deeper sound profile, thanks to its full nylon housings, which result in a clackier and more textured feedback. This switch is noted for its visually appealing silky smoothness and a delicately light 42g actuation force, making it exceedingly easy to press. Overall, the FJ400 is an excellent option for users who prioritize a balanced feel, while the Swift attracts those looking for a more distinctive acoustic response and a lush typing sensation. 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 FJ400 and the HMX Swift, notable differences emerge, particularly in their top housing. The FJ400 features a POM (Polyoxymethylene) top housing, known for its unique sound characteristics that lean towards a deeper and more muted profile. This sound quality is largely attributed to POM's denser structure, which dampens vibrations effectively. In contrast, the Swift's top housing is made of nylon, a material recognized for producing a relatively softer and rounder sound due to its ability to absorb more sound and vibrations. Therefore, while both models aim to deliver a satisfying auditory experience, the FJ400's use of POM results in a distinctly deeper sound, whereas the Swift’s nylon top provides a fuller yet more subdued auditory feedback, showcasing how the choice of housing material can significantly influence the sound profile of these switches.
Turning to the bottom housing, both the HMX FJ400 and the HMX Swift utilize nylon, which creates a consistent foundation in their acoustic performance. The shared characteristics of nylon as a switch housing material mean that users can expect a similar deep and full sound profile when actuating the keys on either model. The nylon bottom housing contributes to a duller and rounder sound, making it an excellent choice for those who prefer a softer typing experience that minimizes sharp and high-pitched sounds. Hence, even though the top housings differ, the nylon bottom in both models ensures that the underlying auditory experience remains predominantly cohesive, providing a sense of continuity in feel and performance.
In terms of overall user experience, the differences between the FJ400’s POM top and the Swift’s nylon top lead to variations in key actuation feedback and sound profile upon release. The POM top housing in the FJ400 likely enhances the tactile experience, resulting in a noticeable pop when releasing the key, while the nylon top in the Swift softens that transition. However, the commonality of the nylon bottom housing across both switches plays a crucial role in harmonizing their overall sound experience. This interplay between contrasting materials allows both switches to provide unique yet complementary auditory profiles—ultimately catering to the diverse preferences of typists and gamers alike, while still anchoring them in a shared sound characteristic due to the nylon bottoms.
Weight
When comparing the HMX FJ400 linear switch and the HMX Swift linear switch, notable differences emerge in their actuation and bottom out forces. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, which categorizes it as a medium force switch. In contrast, the Swift’s actuation force is lighter at 42 grams, with a bottom out force of 50 grams. This means that users of the Swift will experience a gentler push, making it easier for long typing sessions, while the FJ400’s heavier resistance may provide a more substantial tactile experience for users who prefer a stronger keystroke. As such, the FJ400 is the heavier option overall, whereas the Swift is the lighter choice. Ultimately, this differentiation allows users to select a switch that best aligns with their typing style and comfort preferences.
Travel distance
The HMX FJ400 linear switch features a travel distance of 3.8 mm, while the HMX Swift linear switch has a slightly longer travel distance at 3.9 mm. This one millimeter difference may seem minimal, but it can affect the overall feel and responsiveness of the switches. The FJ400, being the shorter option, may cater more to gamers who appreciate quicker keypresses for faster response times. In contrast, the Swift, with its longer travel distance, could appeal to users who prefer a more substantial feel and depth with their keystrokes. Ultimately, choosing between these two switches will depend on individual preferences for tactile feedback and responsiveness, with the FJ400 being better suited for those seeking a rapid response, while the Swift may satisfy those desiring a more traditional typing experience.

Typing experience
When comparing the sound profiles of the HMX FJ400 and HMX Swift linear switches, notable differences emerge. The FJ400 is recognized for its balanced sound profile, which strikes a harmonious blend that is neither too harsh nor overly muted. On the other hand, the HMX Swift deviates from this trend with a deeper sound profile, owing to its full nylon housing. This design choice contributes to a more robust acoustical presence. The Swift features a clackier sound, producing a sharp and snappy noise upon actuation that is crisp and percussive, creating a distinctly lively auditory experience. Thus, while both switches offer unique auditory characteristics, the FJ400 provides a subtle and moderate sound, while the Swift delivers a more resonant and pronounced acoustic signature.
In terms of feel, the HMX FJ400 maintains a level of ambiguity since specific details about its tactile sensation are not provided. Contrasting this is the HMX Swift, which shines with its array of feathery and responsive characteristics. With an actuation force of 42g, the Swift is easy to press, making it less taxing on the fingers during prolonged typing or gaming sessions. This light resistance contributes to a creamy, buttery experience, as well as a bouncy, elastic sensation, enhancing the overall typing experience. Such attributes are particularly favorable for extended use, ensuring comfort and reducing fatigue. Hence, while the FJ400's feel remains undefined in this comparison, the Swift clearly offers a delightful tactile experience that keeps users engaged and comfortable.
In conclusion, while both the HMX FJ400 and HMX Swift switches cater to distinct preferences, they can deliver a satisfying user experience aligned with their unique qualities. The FJ400 offers a balanced sound that complements a wide range of setups, while the Swift's deeper, clackier sound enriches the auditory feedback. On the tactile front, the FJ400 remains an enigma, whereas the Swift clearly excels with its light actuation force and comforting feel. Ultimately, users looking for a balanced sound profile may prefer the FJ400, while those desiring a more pronounced auditory experience along with a feather-light feel could gravitate toward the Swift.
Conclusion
To conclude, choosing between the HMX FJ400 and the HMX Swift linear switches ultimately depends on your typing preferences and the type of experience you are seeking. If you favor a medium bottom-out force and enjoy a balanced sound profile while typing, the FJ400 is a solid option. It is well-suited for those who appreciate a touch of resistance and a more moderated auditory feedback, making it an excellent choice for both typing and gaming. On the other hand, if you prioritize a lighter actuation force for effortless key presses combined with a deeper, clacky sound profile, the Swift may be the better fit. Its 50-gram bottom-out force and silky smooth feel make it particularly appealing for extended typing sessions, allowing for comfortable and fatigue-free usage whether you're gaming, writing, or working. By understanding these nuances, you can select the switch that best aligns with your desired typing experience.
