Housing materials

In comparing the housing materials of the HMX Blue Topaz and the Durock Sea Glass, the most noticeable difference lies in their top housing materials. The Blue Topaz boasts a polycarbonate top housing, known for creating a sharp, high-pitched sound profile due to its stiffness. This results in a clear and resonant sound, making it ideal for switches with RGB lighting. On the other hand, the Sea Glass features a unique Polymer nylon and UHMWPE blend top housing, offering a pleasant sound profile that is bright but not overly sharp. This blend gives the Sea Glass a distinct auditory experience compared to the Blue Topaz.

When it comes to bottom housing materials, both the Blue Topaz and Sea Glass share the use of Nylon in their construction. Nylon is recognized for producing a fuller and deeper sound profile, as it is a softer plastic that absorbs more sound. This results in a duller and rounder sound, contrasting the characteristics of the top housing materials. Despite both switches utilizing Nylon for their bottom housing, the distinct blend of the Sea Glass's top housing material sets it apart from the Blue Topaz in terms of the overall sound profile and typing experience.

Overall, the differences in housing materials between the HMX Blue Topaz and the Durock Sea Glass lead to contrasting sound profiles and typing experiences. While the Blue Topaz offers a sharper and more resonant sound due to its polycarbonate top housing, the Sea Glass provides a unique sound profile that is brighter and more pleasant with its Polymer nylon and UHMWPE blend top housing. Both switches share the use of Nylon for their bottom housing, resulting in a fuller sound profile that differs from the characteristics of their top housing materials. Ultimately, the combination of these housing materials impacts the overall typing experience and sound output of each switch, making them suitable for different preferences and purposes.

Weight

The actuation force and bottom out force of the HMX Blue Topaz linear switch and the Durock Sea Glass linear switch differ in terms of weight. The HMX Blue Topaz has a lighter actuation force of 40 grams and a bottom out force of 48 grams, providing a light typing experience. On the other hand, the Durock Sea Glass features a heavier actuation force of 45 grams and a bottom out force of 62 grams, offering a more substantial typing feel. Those who prefer a lighter touch may opt for the Blue Topaz, making it ideal for extended typing or gaming sessions. In contrast, the Sea Glass is better suited for individuals who prefer a stronger push when typing. Ultimately, the choice between the two switches will depend on personal preference for actuation and bottom out forces.

Travel distance

The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the Durock Sea Glass linear switch has a travel distance of 3.8 mm. Both switches have a relatively short travel distance compared to the traditional 4.0mm and the very shallow 3.0mm travel distances. Gamers may prefer the slightly shorter travel distance of the Sea Glass for faster response times, while those who prefer a more substantial key press may opt for the slightly longer travel distance of the Blue Topaz. Ultimately, the difference of 0.1mm between the two switches' travel distances is minimal, and users can expect similar results regardless of which option they choose.
