Housing materials
The HMX FJ400 and the TTC Ice feature distinct housing materials that significantly influence their acoustic profiles. The FJ400 utilizes a POM (Polyoxymethylene) top housing, which produces a deeper and more muted sound due to its unique composition that allows for expansive sound absorption. In stark contrast, the TTC Ice employs a polycarbonate top housing known for its sharper and crisper sound. The stiffer nature of polycarbonate generates a more pronounced resonance, resulting in a higher-pitched sound profile. Aesthetically, the transparency of polycarbonate allows light from RGB components to shine through, enhancing its visual appeal, a feature not present in the FJ400’s opaque POM material that may limit light diffusion.
When examining the bottom housing of these switches, the differences in materials continue to shape their sound experiences. The FJ400 features a nylon bottom housing, renowned for its softer texture that absorbs sound, leading to a fuller and rounder auditory experience. This contrasts with the TTC Ice’s polycarbonate bottom housing, which replicates the sharpness found in its top component, contributing to a high-pitched and clear sound profile. This divergence in materials means that each switch carries a distinct feel and auditory feedback, with nylon’s capacity to absorb more sound yielding a warmer typing experience compared to the crisp clarity brought about by the polycarbonate used by the Ice.
Despite the contrasting materials used in the top and bottom housings, both the HMX FJ400 and TTC Ice aim to deliver unique auditory experiences. The varying qualities of each housing material play a critical role in shaping the overall performance of the switches. The FJ400 combines the muted depth of POM and the fullness of nylon, while the TTC Ice offers the resonant clarity of polycarbonate in both housings. While the results may differ due to the materials' properties, users can achieve satisfying outcomes by selecting switches that suit their specific sound preferences, whether they crave a warmer tone or a sharper, more defined auditory experience.
Weight
When comparing the HMX FJ400 linear switch and the TTC Ice linear switch, we find some intriguing differences in their actuation forces and bottom out forces. The FJ400 features an actuation force of 50 grams, while the Ice switch has a slightly lighter actuation force of 45 grams, making the Ice the more suitable option for those who prefer a lighter feel, especially during extended typing sessions or gaming. In terms of bottom out forces, the FJ400 has a bottom out force of 58 grams, whereas the Ice switch bottoms out at 60 grams, indicating that while both switches offer a comparable experience, the Ice switch provides a marginally heavier bottoming sensation. Therefore, for users seeking a lighter overall touch, the Ice linear switch stands out, while the FJ400 gives a more balanced push feel. Overall, if users focus on lighter actuation for comfortable typing, they might gravitate towards the Ice switch, but for those who appreciate a more substantial bottoming experience, the FJ400 offers a compelling alternative.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the TTC Ice linear switch, there is a noticeable difference. The FJ400 features a travel distance of 3.8 mm, while the Ice has a shorter travel distance of 3.6 mm. This makes the FJ400 the longer option, providing a more substantial feel when pressed, which may appeal to users who prefer a deeper key travel for comfort and feedback. On the other hand, the Ice, with its shorter travel distance, caters more to users who prioritize quick response times, making it more suitable for gaming or fast-paced typing. Those who enjoy a more immediate tactile experience might lean towards the Ice, while those who favor a more pronounced key press may opt for the FJ400.
