HMX FJ400 vs. Gateron Type A
An in-depth look at the HMX FJ400 and the Gateron Type A switches—which one is the best fit for you?
Overview
When choosing the right mechanical keyboard switch, the FJ400 and Gateron Type A stand out as two appealing linear options, each bringing its own unique characteristics to the table. The HMX FJ400 is celebrated for its balanced sound profile, positioning it as a versatile choice for users who desire both comfort and quiet operations without sacrificing performance. On the other hand, the Gateron Type A shines with its innovation from the Sillyworks' “Project Rehash” series, offering an impressive blend of modern factory lubing techniques and a medium-weight feel. Its deeper sound signature makes it an excellent choice for those who appreciate a more pronounced auditory experience while typing. Ultimately, both switches cater to varied preferences, highlighting the importance of individual needs in selecting the perfect keyboard switch. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that fits your typing style and preferences.

Housing materials
The HMX FJ400 and Gateron Type A switches exhibit a contrasting composition when it comes to their top housing materials. The FJ400 uses POM for its top housing, which is noted for producing a unique sound that leans towards a deeper and more muted profile. This characteristic is significant for those who prioritize sound dampening in their typing experience, as POM's density contributes to a more subdued auditory feedback. Conversely, the Gateron Type A features a nylon top housing, which is more traditional in the switch community. Nylon's softer composition allows it to absorb sounds more effectively than harder plastics, resulting in a sound profile that is also deep but richer and rounder in its response. Both materials strive for an appealing sound experience, yet the POM and nylon’s differing properties lead to distinctive acoustic outcomes.
When we examine the bottom housing of both switches, we find notable similarities between the FJ400's and Type A's nylon materials. Both switches utilize nylon for their bottom housings, which is widely recognized for its ability to produce a full-bodied sound profile. Nylon's softer nature aids in sound absorption, creating a more muffled bottom-out sound that many users find desirable. With the FJ400 and Type A using the same material for their bottom housings, the overall acoustic experience during actuation will be similar, resulting in a profound and rounded auditory feedback under typing conditions. This shared characteristic suggests that users of either switch can expect to achieve comparable sound experiences when it comes to bottoming out the keys.
While the FJ400 and Gateron Type A switches utilize different materials for their top housings, the overall typing experience they offer is brought together when considering their bottom housing, which is made of nylon. The influences of the respective top housings—POM for the FJ400 and nylon for the Type A—will impact the sound profile slightly differently when releasing the keys, emphasizing the top housing's effect on audible feedback. However, with both switches firmly rooted in the use of nylon for their bottoms, any variations in sound and feel between the two switches become a matter of preference in tactile response and sound quality, ensuring that both switches maintain a level of acoustic harmony in their performance. Consequently, users who find solace in a rounded sound experience may appreciate either switch for its own unique take on performance, while still sharing the benefits of nylon in their bottom design.
Weight
The HMX FJ400 linear switch and the Gateron Type A linear switch exhibit some similarities and differences in their actuation and bottom out forces. Both switches have the same actuation force of 50 grams, which makes them feel quite similar when initiating a keystroke. However, the bottom out force varies slightly: the FJ400 has a bottom out force of 58 grams, whereas the Type A's bottom out force is 55 grams. This difference means that while both switches feel relatively light when pressing down to activate them, the FJ400 will require a marginally heavier push when fully bottoming out. Consequently, the Gateron Type A is the lighter switch overall, making it potentially more suitable for long typing sessions or extended gaming, as users might find it less fatiguing. In contrast, those who prefer a more substantial typing experience might opt for the FJ400 due to its slightly heavier bottom out force.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Gateron Type A linear switch, it is clear that they differ slightly. The FJ400 boasts a travel distance of 3.8 mm, while the Gateron Type A has a longer travel distance of 4.0 mm. This means that the FJ400 is the shorter option, offering a slightly more responsive feel that may appeal to gamers looking for quicker actuation. In contrast, the Type A's 4.0 mm travel distance can provide a more traditional and deeper typing experience, which might be more comfortable for users who prefer a less abrupt feedback. Ultimately, the choice between these switches will depend on your preference for responsiveness versus the depth of travel.

Typing experience
In terms of sound, the HMX FJ400 linear switch boasts a balanced sound profile, making it a versatile option for any setting. This characteristic allows it to produce a pleasing auditory experience without being overly intrusive or too muted. In contrast, the Gateron Type A switch has a sound signature that is deeper and more subdued, leaning towards a dampened sound when pressed. This provides a unique auditory experience that is less piercing and more subtle, making it suitable for both casual and professional environments. While the FJ400 offers a balanced tone, the Type A’s deeper sound may appeal to users who appreciate a rich auditory feedback without the burden of loudness.
When it comes to feel, the FJ400 is regarded as a middle-ground option, suggesting it strikes a good balance in terms of actuation force and tactile feedback. However, specific details on its tactile response remain vague. The Gateron Type A, positioned as a medium-weight switch, is designed to provide a soft yet stable typing experience. This makes it an appealing choice for those who favor a comfortable keystroke without excessive resistance. Both switches aim to provide a satisfying and smooth typing experience, though the exact tactile characteristics of the FJ400 are less defined.
In summary, while both the HMX FJ400 and Gateron Type A linear switches cater to users looking for quality and comfort, they each have distinct auditory characteristics and feel profiles. The FJ400 provides a balanced sound that suits a variety of environments, whereas the Type A offers a deeper, more subdued sound signature designed for those who prefer a quieter yet rich auditory experience. Both switches promise satisfying and smooth typing experiences, though the choice may ultimately hinge on personal preference between their unique sound nuances and tactile feedback.
Conclusion
To wrap up, when deciding between the HMX FJ400 linear switch and the Gateron Type A linear switch, consider the specific gaming or typing experience you desire. If you prefer a slightly heavier feel with a medium bottom-out force of 58 grams, the FJ400 might be your best bet; it provides a balanced sound profile that can be especially satisfying for those who enjoy a more pronounced tactile feedback in their keys. On the other hand, if you would like a lighter feel and a more subdued yet neutral sound, the Type A could be your ideal choice, particularly if you're looking for an all-around switch that excels in both home and office environments. The Type A's 55-gram bottom-out force caters well to those who seek a softer touch, while its deeper sound signature suits gamers or typists who want a bit more character. Ultimately, your choice will depend on your personal preferences regarding weight, sound, and overall feel, allowing you to tailor your mechanical keyboard experience to what feels most comfortable and satisfying for you.
