Housing materials

The housing materials of the SP-Star Polaris Purple and the Durock Sea Glass switches have distinct differences. The Polaris Purple features a polycarbonate top housing, which creates a sharper, higher-pitched, and crisper sound profile. This is due to polycarbonate's relatively stiffer plastic, resulting in a clear and resonant sound. Additionally, the translucent nature of polycarbonate makes it ideal for switches with RGB lighting. In contrast, the Sea Glass switch utilizes a unique blend of Polymer nylon and UHMWPE for its top housing. This blend offers a pleasant sound profile that is not particularly sharp but leans towards a brighter tone.

When it comes to the bottom housing, the Polaris Purple uses polycarbonate, which again contributes to a sharper and crisper sound profile. The stiffer plastic of polycarbonate enhances the clarity and resonance of the bottom-out sound and feel when pressing down on the switch. On the other hand, the Sea Glass switch incorporates a Polymer nylon and UHMWPE blend for its bottom housing. Although not specifically described, it can be inferred that this blend might provide a different sound profile compared to the Polaris Purple's bottom housing.

While the two switches have different housing materials for their top and bottom parts, it is important to note that the characteristics of each housing material will impact the overall sound and feel of the switch accordingly. The bottom housing's properties will be more noticeable when pressing down on a key, affecting the bottom-out sound and sensation. Conversely, the top housing's qualities will come into play when releasing a key, influencing the sound produced when the key bounces back. Therefore, the distinction in housing materials between the Polaris Purple and the Sea Glass switch ensures that users can experience varying sound profiles and tactile feedback throughout their typing experience.

Weight

When comparing the actuation force and bottom out force of the SP-Star Polaris Purple tactile switch and the Durock Sea Glass linear switch, there are notable differences. The Polaris Purple has an unavailable actuation force, making it difficult to determine how it compares to the Sea Glass, which has an actuation force of 45 grams. However, in terms of bottom out force, the Polaris Purple requires 67 grams, making it slightly heavier than the Sea Glass which requires 62 grams.

Considering weight as a factor, those who prefer a lighter typing experience may lean towards the Sea Glass with its lower actuation and bottom out force. This lighter feel can be advantageous for extended typing sessions or long gaming periods. On the contrary, individuals seeking a more substantial typing experience may gravitate towards the Polaris Purple. Although the actuation force for the Polaris Purple is unknown, its higher bottom out force suggests a stronger push feel, offering a more robust typing experience.

Overall, the actuation and bottom out forces of these switches exhibit differences, with the Sea Glass being slightly lighter in both aspects. However, without knowledge of the actuation force for the Polaris Purple, it is difficult to draw a direct comparison between the two. Nevertheless, those desiring a lighter typing experience may find similarity in the Sea Glass, while individuals seeking a heavier, more substantial feel may opt for the Polaris Purple.

Travel distance

In comparing the travel distance of the SP-Star Polaris Purple tactile switch and the Durock Sea Glass linear switch, it is clear that the Polaris Purple has a slightly longer travel distance of 4 mm, while the Sea Glass has a slightly shorter travel distance of 3.8 mm. The Polaris Purple falls into the category of a more traditional travel distance, providing a solid depth of 4.0 mm. On the other hand, the Sea Glass offers a slightly shallower travel distance of 3.8 mm. While both options offer a satisfactory distance for key presses, it is important to consider personal preference and use-case scenarios. Gamers, for example, may prefer the shorter travel distance of the Sea Glass for faster response times, while those who prefer a more substantial key press may lean towards the Polaris Purple with its longer travel distance. Ultimately, the choice between these two switches will depend on individual preferences and requirements.
