HMX FJ400 vs. Cherry Nixie
An in-depth look at the HMX FJ400 and the Cherry Nixie switches—which one is the best fit for you?
Overview
When it comes to choosing a mechanical keyboard switch, two noteworthy contenders are the HMX FJ400 and the Cherry Nixie, both linear switches that cater to different preferences within the typing community. The FJ400 stands out as a balanced middle ground in the HMX Film switch lineup, known for its well-rounded sound profile that appeals to gamers and typists alike who seek a satisfying yet unobtrusive keystroke without excessive noise. On the other hand, the Cherry Nixie is a revered classic, celebrated for its substantial heft and textured typing experience, enhanced by Cherry's MX2A update which introduces updated materials and springs that marry traditional feel with modern innovation. While the FJ400 offers versatility and a lighter touch ideal for fast-paced gaming, the Nixie beckons those who appreciate a tactile, thocky sound with a low-pitched feedback that deepens their connection to each keystroke. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that fits your personal style and typing needs.

Housing materials
The HMX FJ400 and the Cherry Nixie switches both utilize nylon for their bottom housing, which contributes significantly to the typing feel and sound profile. Both materials exhibit similar acoustic properties due to nylon's soft nature, which allows it to absorb sound, resulting in a deeper and fuller sound profile. When typing on switches made with nylon bottom housings, users can expect a typing experience characterized by a duller and rounder sound, which fosters a muted yet satisfying auditory feedback. This shared use of nylon as the bottom housing ensures that both switches deliver comparable acoustic qualities, appealing to users looking for a subdued and rich sound while typing.
On the other hand, the top housing materials differ between the two switches: the FJ400 features POM, while the Nixie employs nylon. The use of POM in the FJ400 lends its sound profile a unique character, creating a pleasing and distinct auditory experience. POM is known for producing a deeper, more muted sound than harder plastics, which complements the nylon bottom housing. Conversely, the Cherry Nixie's top housing, made from nylon, resonates with the same qualities as its bottom housing, leading to a more cohesive sound experience with a focus on the overall depth and fullness, but lacking the distinctiveness of the POM. Thus, the difference in materials used for the top housing will influence the overall sound signature of the switches: the FJ400 will offer a slightly varied auditory experience compared to the Nixie's more uniform sound.
When pressing down on a switch, the bottom housing plays a crucial role in the tactile feedback and sound produced as the key bottoms out. In both cases, the nylon bottom housing ensures that the fundamental sound characteristics are primarily focused on a duller sound profile. Meanwhile, the impact of the top housing on the overall sound is more pronounced during the release of the key. The POM in the FJ400 may provide a sharper sound upon releasing the key compared to the more homogenous sound response of the Nixie, which benefits from its nylon top housing. Ultimately, while both switches can achieve similar sound experiences due to their shared use of nylon in the bottom housing, the variation in top housing materials leads to subtly different, yet complementary auditory qualities in each switch.
Weight
When comparing the HMX FJ400 linear switch and the Cherry Nixie linear switch, a notable contrast exists in their actuation and bottom out forces. The FJ400 has an actuation force of 50 grams and a bottom out force of 58 grams, categorizing it as a medium-weight switch. In contrast, the Cherry Nixie requires a heavier actuation force of 63.5 grams and a bottom out force of 80 grams, making it a significantly heavier option. This difference means that typists who prefer a lighter touch will likely favor the FJ400 for its ease of actuation, allowing for prolonged typing or gaming without fatigue. On the other hand, users who enjoy a more substantial typing experience might opt for the Nixie, relishing in the solid feel of its higher resistance. Ultimately, the FJ400 stands out as the lighter switch, while the Nixie appeals to those who appreciate a firmer keystroke.
Travel distance
The HMX FJ400 linear switch has a travel distance of 3.8 mm, while the Cherry Nixie linear switch measures at 4 mm. This makes the FJ400 the shorter option by 0.2 mm, catering well to users who prefer a more responsive experience. The Nixie, with its longer travel distance, may appeal to those who enjoy the substantial feel and depth associated with traditional switches. For gamers who prioritize quick response times, the FJ400 might be the better choice, while users seeking a more deliberate keystroke might lean towards the Nixie. Ultimately, the difference in travel distance accentuates personal preferences in tactile feedback and responsiveness.

Typing experience
When it comes to sound, the HMX FJ400 linear switch offers a balanced sound profile, making it versatile for a variety of typing environments. This means it produces neither an overly pronounced nor excessively muted sound, which can be appreciated by users who desire a more neutral auditory experience without any distractions. In contrast, the Cherry Nixie linear switch is celebrated for its thocky and low-pitched sound, characterized by a deep, rich tonality akin to a satisfying "thud" or soft "knock" upon pressing and releasing the keys. This auditory richness gives the Nixie a distinctive charm, resonating well with enthusiasts who appreciate a more substantial acoustic feedback when typing.
Regarding feel, while details on the FJ400's tactile feedback are not provided, the Nixie switch is known for its textured typing experience. This texture can be felt as noticeable friction during key presses, offering a unique tactile sensation that some users find satisfying and engaging. For those who enjoy a textured switch, the Nixie presents an experience that encourages precise keystrokes, although it may not suit everyone’s preference, especially those who favor a more smooth and seamless pressing motion.
In summary, both the HMX FJ400 and Cherry Nixie linear switches provide distinct auditory and tactile experiences suitable for different preferences. The FJ400 appeals to users looking for a balanced sound, while the Nixie offers a rich auditory profile paired with a textured feel that engages enthusiasts. Depending on your preferences in sound and feel, both switches can deliver enjoyable typing experiences, but the choice will ultimately come down to whether you favor a smoother or a more pronounced feedback in both auditory and tactile sensations.
Conclusion
To conclude, when deciding between the HMX FJ400 and Cherry Nixie linear switches, consider what typing experience you value more. The FJ400 offers a balanced sound profile and a middle-of-the-road bottom-out force of 58 grams, making it a suitable choice for those who prefer a moderate feel and sound without overwhelming feedback. It’s ideal for typists who may find heavy switches too taxing during prolonged use or who desire a quieter operation without sacrificing responsiveness. On the other hand, the Cherry Nixie switches, with their heavier bottom-out force of 80 grams, cater to users who appreciate a substantial, tactile presence when typing. Their thocky, low-pitched sound and textured feel make them perfect for enthusiasts who enjoy an audible and pronounced typing experience. If you are someone who revels in the classic, satisfying sound and feel reminiscent of traditional mechanical switches, go for the Nixie. Ultimately, your choice depends on whether you prioritize a softer, more muted interaction or a robust, textured feedback with a deep auditory response.
