SP-Star Polaris Purple vs. HMX Xinhai
An in-depth look at the SP-Star Polaris Purple and the HMX Xinhai switches—which one is the best fit for you?
Overview
When it comes to choosing between mechanical keyboard switches, two popular options to consider are the SP-Star Polaris Purple and the HMX Xinhai. The Polaris Purple is a tactile switch known for its exhilarating tactile typing experience and snappy sound profile. It is categorized as neutral, mild, and polished. On the other hand, the Xinhai is a linear switch crafted with a unique PA12 top housing and POM stem, providing a softer acoustics profile and a distinctively crisp, higher-pitched resonance. It is categorized as bouncy, clacky, and creamy. Each switch offers its own unique features and benefits, catering to different preferences and typing styles. However, let’s dive in a bit deeper beyond generalities so you can make the best decision on the switch that suits you.

Housing materials
Both the SP-Star Polaris Purple and the HMX Xinhai utilize polycarbonate material for their top housing, which results in a sharper, higher-pitched, and crisper sound profile. This is attributed to the relatively stiffer nature of polycarbonate, providing a clear and resonant sound quality. Additionally, the translucency of polycarbonate makes it ideal for switches with RGB lighting. On the other hand, the Xinhai stands out with its nylon bottom housing, known for creating a deeper and fuller sound profile compared to the polycarbonate bottom housing of the Polaris Purple. Nylon's softer nature absorbs more sound, resulting in a duller and rounder sound overall.
While both switches share the use of polycarbonate in their top housing, the Xinhai diverges with its nylon bottom housing. This contrast in materials affects the overall sound profile and feel of each switch when pressed. The Polaris Purple's combination of polycarbonate top and bottom housings results in a consistent, clear, and resonant sound experience. In contrast, the Xinhai's nylon bottom housing adds a deeper and fuller sound quality, creating a distinct typing experience. The difference in materials showcases how the choice of housing material can impact the overall user experience with mechanical switches.
Ultimately, the choice between the Polaris Purple and the Xinhai comes down to personal preference in sound profile and feel. The polycarbonate top and bottom housings of the Polaris Purple offer a consistent and clear sound experience, ideal for those looking for a sharper and higher-pitched typing sound. On the other hand, the Xinhai's combination of polycarbonate top and nylon bottom housing creates a deeper and fuller sound profile, appealing to users seeking a rounder sound quality. Both switches demonstrate the importance of housing materials in achieving distinct sound and feel characteristics in mechanical keyboards.
Weight
The SP-Star Polaris Purple tactile switch has a bottom out force of 67 grams, which is considered medium-heavy, while the actuation force is not specified. In comparison, the HMX Xinhai linear switch has a lighter bottom out force of 45 grams and an actuation force of 37 grams. The Xinhai is lighter in both actuation and bottom out force compared to the Polaris Purple. The lighter actuation force of the Xinhai may make it more suitable for those who prefer a lighter touch and potentially less finger fatigue during long typing sessions. On the other hand, the Polaris Purple's heavier bottom out force may appeal to users who prefer a more substantial typing experience with a stronger push feel. Ultimately, the choice between the two switches will depend on individual preferences for typing feel and force requirements.
Travel distance
In comparing the travel distance of the SP-Star Polaris Purple tactile switch and the HMX Xinhai linear switch, we can see that the Xinhai has a shorter travel distance of 3.4 mm, while the Polaris Purple has a longer travel distance of 4 mm. The Xinhai's shorter travel distance may appeal to gamers seeking faster response times, while the Polaris Purple's longer travel distance may provide a more satisfying key press for those who prefer a deeper actuation. Both switches offer advantages depending on individual preferences, with the Xinhai offering a quicker actuation and the Polaris Purple providing a more tactile key press experience. Ultimately, choosing between the two switches will depend on whether you prefer a shorter or longer travel distance for your typing or gaming needs.
