HMX FJ400 vs. TTC Flaming Purple

An in-depth look at the HMX FJ400 and the TTC Flaming Purple switches—which one is the best fit for you?

Overview

When exploring the world of mechanical keyboard switches, the HMX FJ400 and the TTC Flaming Purple offer distinct characteristics that cater to different typing preferences. The FJ400, positioned as the middle ground in the HMX Film switch lineup, is celebrated for its balanced sound profile, making it an excellent choice for those who appreciate a more neutral auditory experience while typing. In contrast, the TTC Flaming Purple shines with its unique resonant character, presenting a sound signature that leans towards the bassier side and features a delightful poppy undertone. This gives it a more engaging auditory flair that many find appealing. Additionally, the Flaming Purple's low actuation force of 47g allows for swift, effortless keystrokes, making it particularly inviting for typists who favor speed and responsiveness. Ultimately, each switch has its own strengths, with the FJ400 providing a versatile, balanced sound for a wide range of users, while the Flaming Purple entices with its playful acoustic dynamics and lightweight feel. However, let's dive in a bit deeper beyond generalities so you can best decide on the right switch for you.

Housing materials

When examining the switch housings of the HMX FJ400 and the TTC Flaming Purple, one can immediately note the differences in the top housing materials used. The FJ400’s top housing is made from polyoxymethylene (POM), which is known for producing a deeper and more muted sound profile. This contrasts sharply with the Flaming Purple’s polycarbonate top housing, which creates a sharper and crisper sound due to the stiffer nature of polycarbonate. As a result, while both switches may provide a satisfying typing experience, the FJ400 will yield a sound that is rounder and softer, while the Flaming Purple emphasizes clarity and brightness. This distinction in top housing materials significantly influences the auditory experience each switch offers.

Conversely, both the HMX FJ400 and TTC Flaming Purple utilize nylon for their bottom housing, which impacts the overall sound profile in a similar manner. Nylon, being a softer plastic, effectively absorbs sound, resulting in a deeper and fuller auditory output when typing. As both switches employ nylon in the bottom housing, one can expect a consistency in the fuller sound that emerges, regardless of the differences in the top housing materials. This common factor enhances the experience for users seeking that classic, rich sound, as both switches share that foundational element in their design.

In summary, while the HMX FJ400 and TTC Flaming Purple showcase contrasting materials in their top housings — POM versus polycarbonate — they are aligned in their use of nylon for the bottom housing, leading to a deeper sound profile. The differing sound signatures largely derive from the top housing material, influencing how each switch resonates during typing. Nonetheless, the use of nylon in the bottoms ensures that both switches maintain a level of depth, creating a nuanced experience for the user. Thus, while the sound profile of each switch is impacted by the materials employed, the common nylon element fosters a reliable baseline that will appeal to users who prioritize a deeper sound in their typing experience.

Weight

When comparing the actuation and bottom out forces of the HMX FJ400 linear switch and the TTC Flaming Purple linear switch, notable differences emerge. The FJ400 features an actuation force of 50 grams and a bottom out force of 58 grams, categorizing it as a medium force switch. In contrast, the Flaming Purple has a lighter actuation force of 42 grams and a bottom out force of 47 grams. This makes the Flaming Purple an ideal choice for users seeking a lighter touch, which can facilitate longer typing sessions or extended gaming without excessive strain. On the other hand, the FJ400 appeals to those who prefer a sturdier feel with its heavier actuation and bottom out forces. Ultimately, while both switches serve different preferences, the FJ400's heavier force may provide a more robust typing experience, whereas the Flaming Purple caters to those who favor a lighter action for comfort.

Travel distance

When comparing the travel distances of the HMX FJ400 linear switch and the TTC Flaming Purple linear switch, the FJ400 has a travel distance of 3.8 mm, while the Flaming Purple offers a slightly shorter distance of 3.6 mm. This means the FJ400 provides a more pronounced tactile response, appealing to those who favor a deeper key feel when typing or gaming, as it aligns more closely with the traditional 4.0 mm distance. Conversely, the Flaming Purple, with its shorter travel, caters to gamers and users seeking quicker response times, allowing for faster actuation and potentially improved performance in fast-paced scenarios. Ultimately, if you prefer a more responsive experience, the TTC Flaming Purple is the better choice, while the HMX FJ400 is ideal for those who appreciate a more substantial key press.
