SP-Star Polaris Purple vs. TTC Yunhai
An in-depth look at the SP-Star Polaris Purple and the TTC Yunhai switches—which one is the best fit for you?
Overview
When choosing between mechanical keyboard switches, the SP-Star Polaris Purple and the TTC Yunhai stand out as two distinct options catering to different user preferences. The Polaris Purple, a tactile switch, offers an exhilarating typing experience characterized by a pronounced tactile bump and a snappy sound profile, making each keystroke feel both satisfying and engaging. This switch is ideal for those who enjoy a more pronounced feedback while typing, providing a sense of connection with every press. On the other hand, the TTC Yunhai, known for its linear action, delivers a smoother, more seamless experience, employing an incredibly light actuation force that appeals to typists who favor a gentle, effortless touch. The Yunhai's deep, rounded sound profile adds an auditory dimension to the typing experience, enhancing comfort and ease. Both switches have their unique charm and functionality, with the Polaris catering to tactile enthusiasts and the Yunhai appealing to those who prefer a smooth ride. However, let’s dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the SP-Star Polaris Purple and the TTC Yunhai, notable differences in sound profiles and material characteristics emerge due to their distinct constructions. The Polaris Purple utilizes polycarbonate for both its top and bottom housings, which contributes to a sharper, higher-pitched, and crisper sound profile. This stiffness in the polycarbonate plastic allows for a clear resonance, enhancing the auditory experience, particularly valuable for users who appreciate RGB lighting, as its translucency helps illuminate the switch’s interior. In contrast, the Yunhai employs nylon for both its top and bottom housings, resulting in a decidedly softer and fuller sound profile. Nylon’s ability to absorb sound leads to a deeper, rounder tonal quality, particularly appealing to those who prefer a more muted auditory interaction when typing.
The contrasting characteristics of polycarbonate and nylon are evident not only in their sound profiles but also in their tactile feedback. With the Polaris Purple's polycarbonate housing, users can expect a crisp and immediate response, emphasizing the clarity and detail of each keystroke. This is advantageous for gaming or typing applications where precision and responsiveness are paramount. Conversely, the Yunhai’s nylon housing softens the keystroke impact, offering a more cushioned experience that can be more comfortable for extended typing sessions. The deeper sound absorption of nylon allows for less acoustic spill, creating a quieter typing environment compared to the more resonant and potentially louder profile of the Polaris Purple.
While the notable differences in materials lead to distinctly different auditory and tactile experiences, users seeking a balance can find ways to achieve similar results. For instance, if one were to mix and match housings or consider different configurations within their keyboard builds, they might replicate the nuanced qualities from both materials. By carefully selecting switches or adjusting typing techniques, one could harness the sharpness of polycarbonate with elements of nylon's depth, potentially achieving a hybrid sound and feel that caters to personal preferences. This flexibility in combining different housing materials can enable users to create a customized typing experience that balances the clarity of polycarbonate found in the Polaris Purple with the warmth and fullness characteristic of the Yunhai's nylon housing.
Weight
The SP-Star Polaris Purple tactile switch and the TTC Yunhai linear switch present a notable contrast in their actuation and bottom out forces. The Polaris Purple lacks a specified actuation force, making it difficult to directly compare its initial keystroke responsiveness with the Yunhai, which has a notably lighter actuation force of 42 grams. However, the Polaris Purple's bottom out force stands at 67 grams, categorizing it as medium-heavy, while the Yunhai's bottom out force is lighter at 50 grams. Therefore, if one prefers a lighter typing experience suitable for extended use, the Yunhai would be the preferred option. Conversely, the Polaris Purple caters to individuals who favor a heftier push feel and a more substantial typing experience, given its medium-heavy bottom out force. In summary, those looking for a lighter switch should opt for the Yunhai, while those who appreciate a stronger keystroke will find the Polaris Purple more to their liking.
Travel distance
When comparing the travel distances of the SP-Star Polaris Purple tactile switch and the TTC Yunhai linear switch, the Polaris Purple measures 4 mm, making it the longer option, while the Yunhai has a travel distance of 3.6 mm, indicating a shorter travel distance. This difference suggests that those who favor a more substantial feel when pressing keys may prefer the Polaris Purple for its deeper travel, which can provide a satisfying tactile feedback. Conversely, gamers and users seeking faster response times might lean towards the Yunhai, as its shorter distance allows for quicker actuation. Ultimately, the choice between these two switches comes down to personal preference for depth versus responsiveness.

Typing experience
When comparing the sound profiles of the SP-Star Polaris Purple tactile switch and the TTC Yunhai linear switch, the Polaris Purple is characterized by a snappy acoustic output that lends itself well to fast typing and creates an engaging auditory feedback. In contrast, the Yunhai switch is noted for its deep, rounded sound, offering a more subdued and gentle auditory experience. This difference in sound can cater to personal preferences; while the Polaris Purple's snappiness may excite those who enjoy a vibrant typing session, the Yunhai's deep resonance may appeal to users seeking a more calming ambiance during their typing activities. Ultimately, it’s essential to remember that the overall sound can also be influenced by the keyboard configuration, including the selection of the board and keycaps.
Regarding the tactile feel, the Polaris Purple provides distinct qualities with its big tactile bump, aimed at delivering an exhilarating typing experience. This switch is described as mild and polished, resulting in a smooth key travel that minimizes friction, enhancing the overall tactile feedback. On the other hand, while the Yunhai's specific feel aspects remain unknown, its exceptionally light actuation force suggests a gentle and effortless typing experience possibly without significant tactile feedback. This stark contrast in feel can greatly affect typing dynamics, where the Polaris Purple may energize typists looking for tactile engagement, while the Yunhai could attract those who prefer a more fluid, less straining typing action.
In conclusion, both the SP-Star Polaris Purple and TTC Yunhai switches present unique sound and feel characteristics that cater to different typing preferences. The Polaris Purple excites with its snappy sound and pronounced tactile feedback, making it suitable for those who appreciate a dynamic typing experience. Conversely, the Yunhai switch offers a gentle, rounded sound profile that complements its lightweight action, ideal for users who enjoy effortless typing. While they each have their distinct qualities, the choice ultimately boils down to personal preference and typing style, ensuring that both can provide a satisfying experience when incorporated into a mechanical keyboard setup.
Conclusion
To wrap up, the choice between the SP-Star Polaris Purple tactile switch and the TTC Yunhai linear switch ultimately depends on your personal preferences and typing habits. If you enjoy a pronounced tactile feedback and a snappy sound profile that enhances your typing experience, the Polaris Purple is your go-to option. Its medium-heavy bottom out force of 67 grams provides a substantial feel, making it ideal for users who appreciate deliberate keystrokes while typing or gaming. Conversely, if you prefer a lighter touch and a smoother, effortless keypress, the TTC Yunhai linear switch should be your choice. With its light bottom out force of 50 grams, it offers a unique typing experience characterized by a deep, rounded sound that facilitates fast typing without the fatigue that can accompany heavier switches. In summary, consider the Polaris Purple for a tactile, engaging experience that offers clear feedback and the Yunhai for a lightweight, fluid typing feel that emphasizes speed and comfort. Your ideal switch will align closely with the kind of typing experience you seek, whether that's an invigorating tactile sensation or a gentle, quiet smoothness.
