Housing materials
When examining the housing materials of the SP-Star Polaris Purple and the HMX Xinhai (Heavy), it becomes evident that their differing compositions play a significant role in the sound profiles these switches produce. The Polaris Purple features a polycarbonate top housing, known for its stiffer characteristics, which effectively yields a sharper, higher-pitched, and crisper sound. This is particularly beneficial for RGB lighting applications, as polycarbonate's translucency enhances visual effects. In contrast, the Xinhai (Heavy) employs a nylon top housing, which is softer and consequently generates a deeper, fuller sound profile that is less resonant than that of polycarbonate. This fundamental difference in materials leads to distinct auditory experiences, underscoring how the choice of housing influences the overall sound quality of the switches.
Both switches utilize polycarbonate for their bottom housings in the case of the Polaris Purple, amplifying the crispness of sound, while the Xinhai (Heavy) substitutes with nylon, resulting in a rounder, more muted acoustic output. The impact of the bottom housing on the bottom-out sound and feel when a key is pressed becomes particularly relevant here. While the Polaris Purple’s sharper sound can be attributed to the stiffer polycarbonate, the Xinhai’s deeper tone stems from the sound-absorbing qualities of nylon. It suggests that the combined effect of the housing materials will determine the switch's performance, as each material brings its unique attributes into play. Consequently, the choice of housing at both the top and bottom defines the character of each switch's auditory output.
In conclusion, while the SP-Star Polaris Purple and HMX Xinhai (Heavy) feature different materials for their top and bottom housings, they showcase how variations in plastic composition can lead to distinct sound profiles. The interplay of polycarbonate's rigidity against nylon's softness reveals a nuanced balance between clarity and warmth in keystrokes. When using a switch, it becomes clear that the resultant sound profile and tactile feel are shaped by the qualities native to both materials. If one seeks a sharper auditory feedback and enhanced RGB effects, the Polaris Purple serves that need, whereas the Xinhai provides a different, fuller experience. Ultimately, both switches can achieve desirable results, but the approach and character of those results vary greatly due to the materials used.
Weight
When comparing the SP-Star Polaris Purple tactile switch and the HMX Xinhai (Heavy) linear switch, there are notable differences in their actuation and bottom out forces. The Polaris Purple has an unspecified actuation force, indicating it may have a very light or undetermined initial push, but it does feature a bottom out force of 67 grams, which is classified as medium-heavy. In contrast, the Xinhai (Heavy) switch has a defined actuation force of 55 grams and a bottom out force of 62.5 grams, positioning it within the medium range. This means that the Polaris Purple ultimately allows for a heavier bottoming out experience compared to the Xinhai, which might appeal to users seeking a more substantial typing feel. However, since the actuation force of the Polaris Purple is unknown, users may experience a different tactile response when they begin pressing the key. Overall, those who prefer a lighter typing experience may gravitate towards the Xinhai (Heavy) switch given its defined and manageable actuation force, while those seeking a firmer bottom out without specified actuation force might find the Polaris Purple more appealing.
Travel distance
When comparing the travel distances of the SP-Star Polaris Purple tactile switch and the HMX Xinhai (Heavy) linear switch, it is clear that the Polaris Purple offers a longer travel distance of 4 mm, while the Xinhai (Heavy) boasts a shorter travel distance of 3.4 mm. This distinction means that users who prefer a more pronounced tactile feedback and a deeper key press may find the Polaris Purple more satisfying. In contrast, gamers or individuals who favor quicker response times might lean towards the Xinhai (Heavy) due to its shorter travel distance, which is becoming increasingly popular in modern switches. Ultimately, the choice between the two will depend on personal preferences regarding the balance between travel distance, response time, and tactile feel.
