Housing materials
The housing materials of the HMX FJ400 and the Outemu Dustproof Green differ notably in the composition of their top housings, which results in distinct sound profiles during usage. The FJ400 features a POM top housing, renowned for producing a muted sound profile that leans towards the deeper end of the spectrum. This quality creates an enjoyable auditory experience, characterized by a pleasing yet subtle tone. In contrast, the Dustproof Green utilizes a polycarbonate top housing, which is a stiffer plastic that generates a sharper, higher-pitched, and crisper sound. The translucency of polycarbonate also enhances its suitability for RGB lighting setups, as it allows light to diffuse beautifully, contributing visually to a keyboard's aesthetic.
However, when it comes to the bottom housing, both the HMX FJ400 and Outemu Dustproof Green incorporate nylon, which serves as a classic material in keyboard switches. Nylon is valued for its sound-absorbing properties; its softer composition results in a fuller and deeper sound profile, regardless of the top housing material. This shared characteristic ensures that both switches will deliver a rich auditory experience, even with differing top housings. The nylon bottom housing absorbs impact and vibration, allowing for a rounder, more resonant sound when keys are bottomed out, creating a deeper sense of engagement during typing.
Ultimately, the combination of different top housing materials with an identical bottom housing of nylon means that the overall sound experience can be influenced by both the deeper tones of the bottom and the sharper notes of the top. Users of both the HMX FJ400 and Outemu Dustproof Green can expect a unique typing experience that harmonizes the qualities of softer and firmer plastics. The nuanced differences will manifest in the sound and feel of each switch, with the POM and nylon combination yielding a muted yet rich tone, while the polycarbonate and nylon combination will sound brighter and more crisp. Together, they showcase the diversity and expertise involved in keyboard switch design.
Weight
The HMX FJ400 linear switch and the Outemu Dustproof Green clicky switch exhibit notable differences in their actuation and bottom out forces, which can significantly influence typing comfort and performance. The FJ400 features a lighter actuation force of 50 grams and a bottom out force of 58 grams, making it suitable for users who prefer a softer touch and longer typing sessions without fatigue. In contrast, the Dustproof Green switch has a heavier actuation force of 65 grams and a bottom out force of 80 grams, catering to those who enjoy a more substantial push feel while typing or gaming. These heavier forces can provide a more tactile experience, but they may lead to discomfort during prolonged use for some individuals. Ultimately, the choice between these switches boils down to personal preference for lighter versus heavier actuation and bottom out forces in order to enhance typing or gaming experiences.
Travel distance
When comparing the travel distances of the HMX FJ400 linear switch and the Outemu Dustproof Green clicky switch, there is a notable difference. The FJ400 has a travel distance of 3.8 mm, while the Dustproof Green features a slightly longer travel distance of 4 mm. This means that the FJ400 offers a shorter travel distance, making it more suitable for users who prefer quicker keypresses and faster response times, particularly beneficial for gamers. In contrast, the Dustproof Green’s longer travel distance might appeal to those who appreciate a more pronounced key feeling and a greater depth when typing. Ultimately, this choice comes down to personal preference: if you prefer shorter travel distances for enhanced responsiveness, the FJ400 is the way to go, while the Dustproof Green caters to those who favor a more traditional keypress with a deeper feel.

Typing experience
The sound profile of the HMX FJ400 linear switch is known for its balanced nature, providing a pleasant auditory experience that isn't overly loud or distracting. This makes it suitable for a variety of environments, particularly in office settings where a quieter sound is often preferred. In contrast, the Outemu Dustproof Green clicky switch is designed to create a pronounced click sound with each keystroke, offering a more tactile and auditory feedback that enthusiasts often enjoy. This distinctive click can be satisfying for typists who appreciate the audible confirmation of their actions but may be less suited for shared working spaces due to its louder nature.
When it comes to the feel, the FJ400 switch provides a smooth typing experience characteristic of linear switches, lacking any tactile bump. This allows for uninterrupted keystrokes that many gamers and typists seek for fast and fluid typing. On the other hand, the Dustproof Green switch delivers a tactile feel thanks to its click mechanism, which can enhance typing precision for those who favor a more interactive experience. This tactile feedback often helps users better gauge their keystrokes, making it ideal for typing enthusiasts who appreciate a pronounced response from their switches.
Considering both switches, the HMX FJ400 linear and the Outemu Dustproof Green clicky each cater to different preferences. The FJ400 excels in providing a balanced and smooth typing experience, making it versatile for various tasks and environments. In contrast, the Dustproof Green enhances interactivity with its clicky sound and tactile feedback, catering to those who relish a more pronounced typing experience. Choosing between them ultimately comes down to whether you prefer the subtlety of linear switches or the lively engagement of clicky options.
Conclusion
To sum up, the choice between the HMX FJ400 linear switch and the Outemu Dustproof Green clicky switch largely depends on your typing preferences and intended use. If you enjoy a smooth, linear feel with a balanced sound profile, and you prefer a moderate actuation force that won't tire your fingers over extended typing or gaming sessions, the FJ400 would be the ideal choice for you. This switch is particularly well-suited for fast-paced gaming and quiet office environments where you want to minimize noise while still enjoying a satisfying typing experience. On the other hand, if you crave a tactile feedback with a heavier actuation force and enjoy the distinctive sound of a clicky switch as you type, then the Dustproof Green is your go-to option. This switch provides pronounced audible cues and is perfect for those who appreciate the traditional typing feel, especially for writing and coding tasks where you want to hear each keypress. Ultimately, your selection should align with your personal typing style and sound preference, ensuring that you find the switch that enhances your overall keyboard experience.
