HMX FJ400 vs. Durock POM T1 (Sunflower)
An in-depth look at the HMX FJ400 and the Durock POM T1 (Sunflower) switches—which one is the best fit for you?
Overview
When choosing a mechanical keyboard switch, enthusiasts often find themselves weighing the benefits of linear versus tactile switches. The HMX FJ400, a linear switch, is celebrated for its balanced sound profile and smooth keypress, making it an excellent choice for users who prefer rapid key actions and minimal resistance, often appealing to gamers and typists alike. On the other hand, the Durock POM T1 (Sunflower) offers a compelling alternative for those seeking maximum tactility; its sharp, pronounced feedback and satisfying clack create an invigorating typing experience that many users find addictive. While the FJ400 promises a seamless and quiet performance, the POM T1 engages typists with its pronounced actuation, perfect for those who relish the tactile sensation. However, let's dive in a bit deeper beyond these generalities so you can best decide on the ideal switch for your typing or gaming needs.

Housing materials
The HMX FJ400 and Durock POM T1 (Sunflower) share similarities in their top housing materials, as both utilize POM (Polyoxymethylene) for this component. Both switches are praised for their ability to produce an incredibly pleasing sound profile characterized by a deeper and more muted tonal quality. This similarity suggests that users can expect a consistent auditory experience when typing, as the inherent properties of POM contribute to the muted sound signature. The use of POM in the top housing of both switches indicates they will likely deliver comparable sound characteristics, enhancing the overall typing experience for users who prioritize acoustics in their switches.
However, a notable difference exists in the bottom housing materials of these switches. The FJ400 employs a nylon bottom housing, celebrated for its ability to create a deeper and fuller sound profile due to nylon's softer plastic composition, which absorbs sound more effectively than harder plastics. In contrast, the POM T1 (Sunflower) utilizes a POM bottom housing, which is associated with a similar muted sound profile but may not achieve the same depth and resonance that nylon offers. Thus, when it comes to the overall sound signature and tactile feel, the nylon bottom housing of the FJ400 may produce a more rounded and enveloping sound, while the POM bottom housing of the Durock POM T1 might offer a slightly different acoustic experience.
When pressing either switch, the impact of the housing materials becomes apparent in the overall sensation and sound produced. The bottom housing distinctly influences the bottom-out sound and feel, with the FJ400's nylon housing likely providing a warmer full-bodied resonance upon actuation. Meanwhile, the Durock POM T1's bottom housing will attribute its sound and feel characteristics primarily to its POM material, which maintains a consistent muted profile but may lack the deeper resonance created by nylon. Consequently, while users may find that both switches yield satisfying auditory experiences, the subtle differences in material composition could lead to distinctive preferences based on acoustic and tactile sensations during typing.
Weight
When comparing the HMX FJ400 linear switch and the Durock POM T1 (Sunflower) tactile switch, notable differences in their force characteristics emerge. The FJ400 features an actuation force of 50 grams, which makes it relatively lighter and more suitable for prolonged typing sessions, whether at work or during lengthy gaming marathons. In contrast, the POM T1 does not have a specified actuation force, but its bottom out force is 67 grams, indicating a medium-heavy feel when pressed down fully, which may appeal to users who prefer a more substantial typing experience. The bottom out force of the FJ400 is measured at 58 grams, while the POM T1's heavier bottom out suggests that it delivers a firmer response at the end of a keystroke. Overall, if you're looking for a lighter switch with a softer actuation feel, the FJ400 is the preferable choice, while the POM T1 caters to those who favor a stronger push-back feeling, especially at the bottom of the key press.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Durock POM T1 (Sunflower) tactile switch, it is clear that the FJ400 has a shorter travel distance of 3.8 mm, while the POM T1 measures 4 mm. This means that the Durock POM T1 provides a slightly more pronounced depth when pressed, which might cater to users who enjoy a more substantial key feel. In contrast, the FJ400's shorter travel distance could be preferred by gamers or those favoring quick response times in their typing experience. Both switches are designed with different user preferences in mind, with the FJ400 appealing to those who seek a quicker actuation and the POM T1 satisfying those who appreciate a more traditional, tactile response.
