HMX FJ400 vs. TTC Speed Silver
An in-depth look at the HMX FJ400 and the TTC Speed Silver switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboards, the choice of switches can profoundly influence your typing and gaming experience. On one hand, the HMX FJ400 linear switch serves as a balanced option within the HMX Film switch lineup, providing a harmonious sound profile that appeals to users seeking a moderate and versatile typing experience. Its well-rounded characteristics make it suitable for both casual typing and more intense gaming sessions. On the other hand, the TTC Speed Silver switch is specially engineered for speed, making it ideal for those who prioritize rapid and precise key presses. With a light-medium resistance and a shorter travel distance, the Speed Silver ensures quick actuation for efficient gameplay and swift typing. While both switches offer unique advantages tailored to different preferences, understanding the nuances of each option is essential. 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 HMX FJ400 and the TTC Speed Silver, it's evident that the housing materials used in their designs significantly influence their acoustic profiles. The FJ400 features a polyoxymethylene (POM) top housing, which is well-regarded for producing a sound profile that leans toward the deeper and more muted end of the spectrum. This material’s inherent properties contribute to a unique auditory experience, where notes resonate softly and create a pleasing, enveloping atmosphere. In contrast, the Speed Silver employs a polycarbonate top housing, which is known for its stiffness and clarity, resulting in a sharper and more high-pitched sound. The contrast between the two materials suggests that while the FJ400 offers a softer auditory experience, the Speed Silver is geared toward users seeking crispness and definition in their keystrokes.
In terms of bottom housing, both the HMX FJ400 and TTC Speed Silver utilize nylon, a classic choice that helps balance the sound profiles of the switches. Nylon's softer nature allows for a deeper, fuller sound that dampens acoustics effectively, isolating vibrations and delivering a rounder sound experience. While this property remains consistent across both models, the performance diverges primarily due to the differences in their top housing materials. Consequently, users of both switches will enjoy the full-bodied sound that nylon provides, but the unique characteristics brought by the top housing – POM for the FJ400 and polycarbonate for the Speed Silver – lead to divergent auditory experiences. Overall, if the bottom housing influences the sound upon bottoming out, the top housing shapes the sound released when the key is released.
Ultimately, while the HMX FJ400 and TTC Speed Silver both feature nylon bottom housings that contribute to a rich and resonant sound, the distinct materials used in their top housings create different auditory personalities. Users can expect a muted auditory experience from the FJ400 thanks to the POM top housing, whereas the Speed Silver is likely to deliver a more defined and high-energy sound profile due to its polycarbonate design. However, both switches can achieve pleasing results in their acoustic output; by integrating the deeper resonance from nylon, complementing the properties of their respective top housings, either switch can cater to users' preferences, whether they prioritize warmth or clarity in their typing experience.
Weight
When comparing the HMX FJ400 linear switch and the TTC Speed Silver linear switch, there are notable differences in both 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 medium in weight. In contrast, the Speed Silver features a lighter actuation force of 45 grams along with a bottom out force of 55 grams, classifying it as medium-light. This means that the Speed Silver is the lighter option overall, making it potentially more suitable for extended typing sessions or gaming, where less force can help reduce finger fatigue. Meanwhile, the heavier FJ400 may appeal to those who prefer a more substantial typing experience with a firmer push feel. Both switches provide similar bottom out dynamics, but their different actuation forces will affect the experience based on user preference for light versus heavier typing feedback.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the TTC Speed Silver linear switch, it's evident that they cater to different preferences in key feel and responsiveness. The FJ400 boasts a travel distance of 3.8 mm, making it the longer option between the two. In contrast, the Speed Silver has a shorter travel distance of 3.4 mm, which may appeal more to gamers seeking quicker actuation and faster response times. The distinction in travel distances not only affects the tactile feedback but also influences the overall typing experience; those who prefer a more pronounced depth will appreciate the FJ400, while those favoring snappiness may find the Speed Silver more to their liking. Ultimately, the choice between these switches will depend on individual preferences for responsiveness versus key travel depth.

Typing experience
The sound profile of the HMX FJ400 linear switch is considered balanced, making it versatile for different environments and ensuring it won’t be overly distracting in either a home or office setting. In contrast, the TTC Speed Silver linear switch boasts a pristine sound profile that leans towards neutrality, which positions it well for a variety of uses, whether for gaming or typing. If you opt for either switch, you can expect a moderate sound experience from both, allowing for an unobtrusive backdrop while you type or game. However, bear in mind that the acoustic performance can also be influenced by factors such as your choice of keyboard, keycap materials, and even the overall setup, meaning that personal preferences might slightly alter the perception.
When it comes to feel, the HMX FJ400 serves as a middle ground switch, likely providing a smooth experience without any distinctive elements that could define its tactile sensation. On the other hand, the TTC Speed Silver is characterized as mild and polished, giving users a gentle but satisfying experience with a refined, smooth key travel due to potentially superior materials and factory lubrication. Users looking for a gentle, polished experience may find the Speed Silver more appealing, whereas the FJ400 offers its own understated charm, suitable for a more balanced approach.
In summary, both the HMX FJ400 and the TTC Speed Silver linear switches have their unique qualities that cater to different preferences. The FJ400 offers a balanced sound profile without compromising on versatility, while the Speed Silver provides a pristine and neutral sound, making it an excellent choice for fast and precise typing. In terms of feel, the FJ400 presents itself as a middle-ground option, whereas the Speed Silver excels with its mild and polished qualities.
