HMX Blue Topaz vs. Gateron Lunar Probe
An in-depth look at the HMX Blue Topaz and the Gateron Lunar Probe switches—which one is the best fit for you?
Overview
The HMX Blue Topaz and the Gateron Lunar Probe are both linear mechanical keyboard switches, each offering unique features that cater to different typing preferences. The Blue Topaz stands out for its smooth actuation and lightweight feel, making typing a breeze with its easy-to-press keys and clacky sound signature. On the other hand, the Lunar Probe distinguishes itself with Gateron's dual rail mechanism for stable and consistent keypresses, along with a pre-lubed linear sensation and a subtle sound profile. While the Blue Topaz focuses on providing a visually and audibly pleasing typing experience, the Lunar Probe emphasizes stability and smoothness. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
Both the HMX Blue Topaz and the Gateron Lunar Probe utilize polycarbonate for their top housing, which results in a sharper, higher-pitched, and crisper sound profile when typing. This is due to the stiffness of polycarbonate, which leads to a more resonant sound. Additionally, the translucency of polycarbonate makes it ideal for switches that plan to use RGB lighting. However, despite both switches using the same material for the top housing, they may have different designs or thicknesses that could affect the sound produced.
On the other hand, the Blue Topaz and Lunar Probe differ in their choice of material for the bottom housing, with the Blue Topaz using nylon and the Lunar Probe also utilizing nylon. Nylon is known for creating a deeper and fuller sound profile when typing, as it is a softer plastic that absorbs more sound than harder plastics. This results in a duller and rounder sound overall. This difference in material for the bottom housing could lead to a variation in the overall typing experience between the two switches, despite having similar top housings.
Overall, the combination of polycarbonate top housing and nylon bottom housing in the Blue Topaz and Lunar Probe switches allows for a unique typing experience. The split qualities of each housing material affect the sound both when pressing down on a key and when letting go. The impact of the bottom housing is more noticeable on the bottom-out sound and feel, while the top housing has a greater influence on the sound when releasing a key. Despite using different materials for the bottom housing, both switches maintain a balance between sharpness and depth in their sound profiles, providing users with a satisfying typing experience.
Weight
The HMX Blue Topaz linear switch and the Gateron Lunar Probe linear switch both offer relatively light actuation and bottom out forces compared to other switches on the market. The Blue Topaz has a slightly lighter actuation force of 40 grams compared to the Lunar Probe's 45 grams, while both have a relatively light bottom out force of 48 grams and 50 grams respectively. This means that typing on either switch will not require a significant amount of force, making them suitable for those who prefer a lighter typing experience. Both switches offer a similar typing experience in terms of force required, so users can expect comparable results regardless of which one they choose. Choosing between the two may come down to personal preference in terms of the specific feel each switch provides.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the Gateron Lunar Probe linear switch has a slightly shorter travel distance of 3.6 mm. Both switches fall within the range of shorter travel distances that are popular among gamers for faster response times. The Blue Topaz offers a slightly deeper press compared to the Lunar Probe, which may be preferred by some individuals who enjoy a more substantial key press. Ultimately, the choice between the two switches will depend on personal preference for travel distance and the desired level of key press responsiveness.

Typing experience
When it comes to sound, the HMX Blue Topaz linear switch offers a clacky sound signature, providing a sharp and snappy sound that adds an element of excitement to each keystroke. On the other hand, the Gateron Lunar Probe linear switch provides a more subtle sound profile, ensuring a quieter typing experience that may be preferred in quieter environments. Both switches offer unique sound characteristics that cater to different preferences, so choosing between the two would depend on whether you prefer a more pronounced or subdued typing sound.
Moving on to feel, the HMX Blue Topaz switch is known for its easy-to-press nature, offering a lightweight feel that requires minimal force to activate each key. This feature enhances typing comfort and reduces finger fatigue during long typing sessions, making it a popular choice for those who prioritize typing ease. In comparison, the Gateron Lunar Probe switch boasts an incredibly smooth and pre-lubed linear sensation, providing a consistent and stable typing experience. While the specific tactile feel of the Lunar Probe switch is not detailed, it is likely to offer a smooth and seamless typing experience that may appeal to those who value smooth key actuation.
In conclusion, both the HMX Blue Topaz linear switch and the Gateron Lunar Probe linear switch offer unique qualities that cater to different preferences. The Blue Topaz stands out with its clacky sound profile and easy-to-press feel, providing a distinct typing experience that focuses on light actuation and audible feedback. On the other hand, the Gateron Lunar Probe switch prioritizes smooth keypresses and stability, offering a more subtle sound profile and a consistent typing feel. Depending on whether you prefer a louder, tactile typing experience or a smoother, quieter one, either switch could provide a satisfying typing experience. Ultimately, both switches are designed to enhance the overall typing experience, so users can expect similar results in terms of performance and quality.
