HMX EVA vs. Gateron Lunar Probe
An in-depth look at the HMX EVA and the Gateron Lunar Probe switches—which one is the best fit for you?
Overview
When it comes to choosing the right mechanical keyboard switch, the HMX EVA and Gateron Lunar Probe stand out as two compelling options within the linear category, each offering unique characteristics suited for different preferences. The HMX EVA, inspired by the striking colors of Evangelion Unit-01, is celebrated for its resonant sound signature and exceptionally smooth typing experience, making it an attractive choice for those who value both aesthetics and tactile satisfaction. On the other hand, the Gateron Lunar Probe shines with its innovative dual rail mechanism, which promises stable and consistent keypresses, complemented by a pre-lubed linear sensation that ensures an effortless typing experience with a subtle sound profile. While both switches deliver the smoothness characteristic of linear switches, they cater to different users—those seeking a vibrant, inspiring typing environment might gravitate toward the EVA, while those in pursuit of reliable stability may prefer the Lunar Probe. However, let's dive in a bit deeper beyond generalities so you can best decide which switch is ideal for you.

Housing materials
When comparing the housing materials of the HMX EVA and the Gateron Lunar Probe, significant differences emerge, particularly in their top housing compositions. The HMX EVA employs a nylon top housing, which is known for its softer, sound-absorbing qualities. This results in a typing experience characterized by a deeper, fuller sound profile. In contrast, the Gateron Lunar Probe features a polycarbonate top housing, which provides a sharper, higher-pitched auditory experience. The rigidity of polycarbonate enhances clarity and resonance, making it a popular choice, especially for switches that incorporate RGB lighting due to its translucency. Therefore, while the EVA's nylon creates a warm and rounded sound, the Lunar Probe's polycarbonate delivers a crisp and distinct auditory feedback.
In reviewing the bottom housings of both switches, one sees a notable similarity: both the HMX EVA and Gateron Lunar Probe utilize nylon. This shared material leads to analogous sound characteristics, as nylon produces a deeper and fuller sound profile regardless of whether it is situated on the top or bottom housing. Consequently, in both switches, the typing experience when bottoming out will yield a similar auditory result due to the nylon's inherent qualities. This consistency in material choice for the bottom housing ensures a common ground between the two products, allowing users to appreciate that aspect of sound and feel across both switch types.
Ultimately, the combination of different materials for the top and bottom housings in both switches results in a unique interplay of sound and tactile feedback. While the HMX EVA presents a rounded and soft auditory experience thanks to its nylon top housing and similar bottom material, the Gateron Lunar Probe distinguishes itself with a brighter sound profile attributed to its polycarbonate top. However, both switches leverage nylon in their bottom housings, converging in the bottom-out sound and feel. This duality—where the EVA fosters a classic and warm typing experience and the Lunar Probe offers a more pronounced, resonant one—highlights the diverse preferences within the mechanical keyboard community and the varying impacts of housing materials on overall typing experience.
Weight
When comparing the actuation and bottom out forces of the HMX EVA linear switch and the Gateron Lunar Probe linear switch, we find that both switches are categorized as light, but they do exhibit some differences. The EVA switch has an actuation force of 42 grams and a bottom out force of 48 grams, while the Lunar Probe requires a slightly higher actuation force of 45 grams and a bottom out force of 50 grams. This means that the EVA switch is lighter than the Lunar Probe, making it potentially more suitable for extended typing sessions or gaming, as it requires less effort to actuate. In contrast, the slight increase in force with the Lunar Probe may appeal to users who prefer a more substantial typing experience. Both switches, however, provide a relatively similar feedback mechanism due to their close force specifications, ensuring that users can expect a comparable tactile experience, albeit with a marginally heavier feel in the case of the Lunar Probe.
Travel distance
Both the HMX EVA linear switch and the Gateron Lunar Probe linear switch feature a travel distance of 3.6 mm, indicating that they provide an identical experience when pressed down. As the travel distance is the same for both switches, users can expect similar tactile feedback and responsiveness, which can contribute to a consistent typing or gaming experience. Therefore, there is no shorter or longer switch in this comparison as both switches maintain equal travel distance.

Typing experience
In terms of sound, the HMX EVA switch is characterized by its resonant sound signature, which can give a pronounced auditory feedback when typing, making it stand out in a crowded environment. This sound quality can be particularly enjoyable for those who appreciate a more expressive typing experience. On the other hand, the Gateron Lunar Probe switch features a subtle sound signature, which is likely to be quieter and more understated in comparison. This makes the Lunar Probe a strong choice for users who value discretion in their typing sessions. It's important to remember that the final sound produced by either switch will also depend on the choice of keyboard case and keycaps, adding a layer of customization to the auditory profile.
When it comes to feel, the HMX EVA switch excels with its silky smooth typing sensation, offering a very pleasant and fluid experience as your fingers glide over the keys. This makes it an attractive option for those who want a premium typing experience. The Gateron Lunar Probe also boasts an incredibly smooth, pre-lubed linear sensation thanks to Gateron's dual rail mechanism, which enhances stability and reliability during keypresses. While both switches aim to deliver a smooth typing experience, the EVA’s texture might feel slightly different due to its unique design elements, making each switch a viable choice for different preferences.
Considering all this information, both the HMX EVA and Gateron Lunar Probe linear switches appeal to different aspects of the typing experience. While the EVA offers a more resonant sound and silky feel, the Lunar Probe emphasizes subtlety and stability with its pre-lubed smoothness. Ultimately, your personal preferences regarding sound and feel will guide you toward the switch that best suits your typing style; if you're looking for a more expressive experience, the EVA shines, but if you prefer a refined and stable typing sensation, the Lunar Probe stands out.
Conclusion
To conclude, when deciding between the HMX EVA linear switch and the Gateron Lunar Probe linear switch, consider your priorities in both tactile feedback and overall experience. If you’re drawn to aesthetics and prefer a resonant sound signature combined with a silky smooth typing feel, the HMX EVA might be your best choice. Its light 48-gram bottom-out force offers an effortless keystroke, making it ideal for long typing sessions or gaming marathons where you want quick actuation with minimal effort. On the other hand, if you value stability and consistency, the Gateron Lunar Probe is an excellent option. With its slightly firmer 50-gram bottom-out force and a novel dual rail mechanism, it ensures a solid typing experience. The pre-lubed smoothness and subtle sound signature make it particularly appealing if you desire a well-rounded linear switch that feels both refined and reliable. Ultimately, your decision should hinge on whether you lean towards the unique aesthetic and sound profile of the EVA or the solid performance and consistency offered by the Lunar Probe.
