Housing materials
The HMX FJ400 and the HMX Twilight utilize different materials for their top housings, which results in distinct sound profiles despite some similarities. The FJ400 features a POM (Polyoxymethylene) top housing, known for its ability to deliver a pleasing sound characterized by deeper tones and relative muteness. In contrast, the Twilight employs a nylon top housing, which is part of its classic design. Although nylon also produces a refined sound, it generates a fuller and more rounded profile, thanks to its softer nature that absorbs sound more effectively than POM. Thus, while both switches can create satisfying acoustics, the FJ400 may cater to those seeking a more subdued auditory experience, whereas the Twilight appeals to users who enjoy a richer sound.
In terms of bottom housings, both the FJ400 and the Twilight utilize nylon, solidifying their similarities. The bottom housing plays a crucial role in the overall typing experience since it significantly influences the bottom-out sound and feel when pressing the keys. With both switches featuring nylon materials at the bottom, users can expect deep and full sound profiles that are consistent across both models. This commonality in bottom housing ensures that both switches deliver a satisfying tactile response, regardless of the differences in their top materials. Consequently, regardless of the top housing variation, the similarities in bottom housing promise an enjoyable user experience.
Overall, the contrasting materials of the top housings lead to distinct sound profiles in the HMX FJ400 and HMX Twilight, yet their shared nylon bottom housings unify the tactile experience. While the FJ400 offers a more muted sound through its POM top, the Twilight draws on nylon’s acoustic properties to elicit more pronounced audio feedback. Users looking for specific sound characteristics may gravitate towards one switch over the other, but both provide an appealing and rich auditory experience due to their nylon bottom housings. Thus, both models cater to different preferences, while still ensuring a level of consistency in the sound and feel derived from their shared housing material.
Weight
The HMX FJ400 linear switch and the HMX Twilight linear switch differ notably in terms of actuation and bottom out forces, catering to different user preferences. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, which offers a medium resistance, making it suitable for those who prefer a more substantial typing experience. In contrast, the Twilight features a lighter actuation force of 42 grams and a bottom out force of 50 grams, appealing to users who favor a lighter touch for prolonged typing or gaming sessions. As a result, the FJ400 is the heavier option, which could lead to fatigue over extended use for some typists, while the Twilight's lightness enhances comfort and ease of use. Therefore, individuals seeking a more tactile feedback should lean towards the FJ400, whereas those looking for a swift and effortless keystroke experience may find the Twilight to be the better choice.
Travel distance
The HMX FJ400 linear switch has a travel distance of 3.8 mm, while the HMX Twilight linear switch features a slightly longer travel distance of 3.85 mm. This indicates that the FJ400 is the shorter option, providing a more responsive feel that many gamers may prefer for quicker keystrokes. In contrast, the Twilight, with its longer travel distance, may offer a more substantial feedback and depth during typing, which could be appealing to users who favor a more tactile experience. While both switches are similar in their design and functionality, the FJ400's shorter travel caters to a more rapid response, whereas the Twilight is better suited for those who appreciate a more pronounced keystroke.

Typing experience
In terms of sound, the HMX FJ400 linear switch produces a balanced profile that strikes a middle ground among HMX Film switches, making it versatile for various typing and gaming environments. It delivers a satisfying tone without overwhelming the user, which can be appealing for those who appreciate a more understated auditory experience. On the other hand, the HMX Twilight linear switch, with its extended 3.85mm travel distance, results in a slightly quieter sound, yet it manages to maintain the signature clacky characteristics typical of HMX switches. This combination means that while both switches provide a pleasant auditory experience, the FJ400 might be better suited for those seeking a more prominent sound, while the Twilight caters to users who prefer quieter keystrokes but still want some auditory feedback.
When it comes to feel, the FJ400 is noted for its balance, allowing for a smooth typing experience that can be both tactile and linear, making it a good choice for long typing sessions or complex gaming maneuvers. This balanced feel means that it doesn’t lean too heavily into either end of the spectrum, appealing to a wide range of users. In contrast, the Twilight switch offers a unique sensation due to its longer travel distance, which may provide a different kind of tactile experience that may be preferred by some users. The extended travel can lead to a more deliberate keystroke that emphasizes purpose, potentially making it ideal for tasks that require careful input.
In summary, both the HMX FJ400 and HMX Twilight linear switches cater to users seeking different auditory and tactile experiences. The FJ400 provides a more balanced sound and feel, while the Twilight offers a quieter profile with a longer travel distance. Depending on your typing style and preferences, each switch can serve different purposes effectively; if you appreciate nuanced sound without excessive noise, the Twilight may be your pick, whereas if you prefer a more pronounced auditory profile without sacrificing comfort, the FJ400 will deliver satisfying results. Ultimately, both switches are capable of delivering enjoyable experiences, and your choice will largely depend on your specific needs and typing preferences.
Conclusion
To conclude, choosing between the HMX FJ400 linear switch and the HMX Twilight linear switch ultimately depends on your personal preferences and typing style. If you favor a medium actuation force with a balanced sound profile, the FJ400 is an excellent choice, offering a responsive feel that strikes a nice equilibrium between feedback and quietness. This makes it ideal for both typing and gaming scenarios where you want to feel the key presses without the noise overwhelming your environment. On the other hand, if you prefer a lighter touch with an extended travel distance, then the Twilight switch may be the better option for you. Its 50-gram bottom-out force allows for a softer keystroke, making it more forgiving for long typing sessions, while the signature clacky sound adds a satisfying auditory experience that many users enjoy. In essence, if you value a robust typing experience and are willing to sacrifice some quietness, go for the FJ400; but if you lean towards a lighter, quieter touch with a bit of personality, the Twilight will suit you well.
