Housing materials
The HMX Blue Topaz and SP-Star Polaris Gray both feature polycarbonate top housings, which create a sharper, higher-pitched, and crisper sound profile due to the material's stiffness. This makes them ideal for switches that prioritize a clear and resonant sound. However, when it comes to the bottom housing, the Blue Topaz utilizes nylon, which provides a deeper and fuller sound profile by absorbing more sound than harder plastics. In contrast, the Polaris Gray's polycarbonate bottom housing continues to enhance the sharp and clear sound profile of the switch.
Despite the differences in their bottom housing material, both the HMX Blue Topaz and SP-Star Polaris Gray feature polycarbonate top housings that offer similar benefits. The use of polycarbonate allows both switches to produce a more defined sound profile with a focus on clarity and resonance. Additionally, the translucency of polycarbonate is advantageous for switches intended for use with RGB lighting, adding a visually appealing element to the overall design. This makes them both suitable choices for those looking for a switch with a sharp and crisp sound output.
When considering the overall performance of the switches, the impact of the housing material becomes apparent in the sound and feel of typing. The qualities brought by the bottom and top housing materials are divided between the two components, with the bottom housing influencing the bottom-out sound and feel, while the top housing affects the sound when releasing a key. As such, users can expect differences in sound and typing experience based on the choice of housing material in each switch, whether it be the softer nylon of the Blue Topaz or the stiffer polycarbonate of the Polaris Gray.
Weight
When comparing the actuation force and bottom out force of the HMX Blue Topaz linear switch and the SP-Star Polaris Gray linear switch, it is evident that they have significant differences. The Blue Topaz has a lighter actuation force of 40 grams and a bottom out force of 48 grams, making it a more lightweight option. On the other hand, the Polaris Gray has a heavier bottom out force of 67 grams, although the actuation force is unknown. Those who prefer a lighter typing experience may opt for the Blue Topaz, while those who prefer a more substantial feel when typing may lean towards the Polaris Gray. Ultimately, the choice between the two switches will depend on individual preferences for actuation and bottom out forces, with the Blue Topaz offering a lighter touch and the Polaris Gray providing a heavier typing experience.
Travel distance
The travel distance of the HMX Blue Topaz linear switch is 3.9 mm, while the SP-Star Polaris Gray linear switch has a travel distance of 4 mm. Both switches have relatively short travel distances compared to the traditional 4.0mm distance. Gamers may prefer the Blue Topaz for its slightly shorter travel distance, resulting in faster response times. On the other hand, those who prefer a more substantial key press may opt for the Polaris Gray with its slightly longer travel distance. Ultimately, the choice between the two switches will depend on personal preference for travel distance and key press feel.
