HMX Blue Topaz vs. KTT Lightning
An in-depth look at the HMX Blue Topaz and the KTT Lightning switches—which one is the best fit for you?
Overview
When comparing the HMX Blue Topaz and the KTT Lightning mechanical keyboard switches, both being linear switches, there are some key differences to consider. The Blue Topaz stands out for its smooth actuation and lightweight feel, making typing effortless and pleasant. Additionally, its glittery housing adds a visually appealing aspect paired with a clacky sound signature. On the other hand, the KTT Lightning switches are known for their speed and responsiveness, particularly beneficial for fast-paced gaming where milliseconds can make a difference. With a slick typing feel and a clacky sound profile, the Lightning switches offer a different experience compared to the smooth actuation of the Blue Topaz. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials used in both the HMX Blue Topaz and the KTT Lightning switches are quite similar. Both switches feature a polycarbonate top housing, which is known for creating a sharper, higher-pitched, and crisper sound profile. This is because polycarbonate is a stiffer plastic that leads to a clearer and more resonant sound. Additionally, the translucent nature of polycarbonate makes it ideal for switches with RGB lighting. However, the key difference lies in their bottom housings. The Blue Topaz utilizes a nylon bottom housing, which results in a deeper and fuller sound profile due to nylon's softer nature that absorbs more sound. On the other hand, the Lightning switch also uses a nylon bottom housing, providing a similar typing experience to the Blue Topaz.
Despite the similarities in their top housing materials, the differences in their bottom housing materials can have a significant impact on the overall typing experience. The nylon bottom housing of both the Blue Topaz and the Lightning switches affects the bottom-out sound and feel, resulting in a deeper and fuller sound profile. This is in contrast to the impact of the top housing on the sound when releasing a key. While both switches have a polycarbonate top housing generating a clear and resonant sound, the split qualities between the top and bottom housing materials offer a unique typing experience for each switch. The combination of polycarbonate and nylon in the Blue Topaz and Lightning switches ensure a well-rounded sound profile that caters to different preferences.
Ultimately, the housing materials of the HMX Blue Topaz and the KTT Lightning switches play a crucial role in shaping the sound profile and typing experience of each switch. The polycarbonate top housing in both switches creates a sharp and clear sound, while the nylon bottom housing adds depth and fullness to the overall sound profile. While the differences between the top and bottom housing materials may have subtle effects on the typing experience, both switches offer a unique combination of materials that cater to various preferences. Whether you prefer a sharper sound with the Blue Topaz or a deeper sound with the Lightning, the housing materials in each switch contribute to a distinct typing experience.
Weight
The HMX Blue Topaz linear switch has a lighter actuation force and bottom out force compared to the KTT Lightning linear switch. The Blue Topaz requires 40 grams of force to actuate a keystroke and 48 grams to bottom out, while the Lightning needs 43 grams to actuate and 50 grams to bottom out. Both switches are relatively light, making them suitable for extended typing sessions or gaming. However, if someone prefers a slightly stronger push feel, they may opt for the Lightning switch for a more substantial typing experience. Ultimately, the choice between the two switches will depend on individual preferences for actuation and bottom out forces.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, which is longer than the 3 mm travel distance of the KTT Lightning linear switch. The Blue Topaz offers a slightly deeper key press experience compared to the Lightning switch. If you prefer a switch with more travel distance for a more substantial key press feel, the Blue Topaz might be the better option for you. On the other hand, if you prioritize faster response times and prefer a shallower key press, the Lightning switch with its shorter travel distance could be the more suitable choice. Gamers, in particular, tend to favor switches with shorter travel distances for quicker input recognition. Ultimately, the choice between the two switches will depend on your personal preference for key press depth and responsiveness.
