SP-Star Polaris Purple vs. TTC Speed Silver
An in-depth look at the SP-Star Polaris Purple and the TTC Speed Silver switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, there are many options to consider. Two popular choices are the SP-Star Polaris Purple, a tactile switch, and the TTC Speed Silver, a linear switch. Both switches have their own distinct characteristics that make them appealing to different types of typists. The Polaris Purple is best known for its exhilarating tactile typing experience, thanks to a big tactile bump. This switch provides a satisfying feedback and a snappy sound profile. On the other hand, the Speed Silver is perfect for those who prioritize speed and precision. With a reduced travel distance, these linear switches allow for quick and effortless actuation. They also offer a lighter level of resistance and a pristine sound profile. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the SP-Star Polaris Purple and the TTC Speed Silver, specifically the top housing, share many similarities. Both switches utilize polycarbonate for their top housing, which results in a sharper, higher-pitched, and crisper sound profile. The stiffness of polycarbonate plastic contributes to a clear and resonant sound, making it an ideal choice for those seeking a more defined auditory experience. Additionally, the translucency of polycarbonate allows for vibrant RGB lighting effects, enhancing the overall aesthetics of the switches.
However, when it comes to the bottom housing, the Polaris Purple and the Speed Silver differ in their choices of materials. The Polaris Purple utilizes polycarbonate for its bottom housing, similar to its top housing. This ensures that the qualities brought by polycarbonate are distributed evenly in both the top and bottom of the switch. Conversely, the Speed Silver features a nylon bottom housing. Nylon is known for its ability to absorb sound, resulting in a deeper and fuller sound profile. This softer plastic creates a duller and rounder sound, which may be preferred by those who enjoy a more muffled typing experience.
Despite the difference in bottom housing materials, both switches provide an excellent typing experience. The qualities of the bottom housing, which have a significant impact on the bottom-out sound and feel, are distinct for each switch. However, the impact of the top housing, which influences the sound when releasing a key, remains consistent. Therefore, users of either switch can expect similar results in terms of the crisp and resonant sound produced upon releasing a key. Ultimately, the choice between the SP-Star Polaris Purple and the TTC Speed Silver will depend on personal preferences for the overall sound profile and feel during typing.
Weight
When comparing the SP-Star Polaris Purple tactile switch and the TTC Speed Silver linear switch, there are notable differences in their actuation force and bottom out force. The Polaris Purple's actuation force is unavailable, while the Speed Silver has an actuation force of 45 grams. In terms of bottom out force, the Polaris Purple requires 67 grams, making it medium-heavy, while the Speed Silver requires 55 grams, making it medium-light.
The actuation force of a switch determines the force required to trigger a keystroke. In this case, the exact actuation force of the Polaris Purple is unknown, but it is important to note that the actuation force of the Speed Silver is lighter at 45 grams. This means that the Speed Silver requires less force to register a keystroke compared to the Polaris Purple.
On the other hand, the bottom out force measures the force required to fully press down the switch. The Polaris Purple has a heavier bottom out force of 67 grams, providing a more substantial typing experience for those who prefer a stronger push feel. In contrast, the Speed Silver has a lighter bottom out force of 55 grams, which may be preferable for individuals who prefer a lighter switch.
Weight is an important consideration when choosing a switch, as it can impact typing comfort and endurance. Some prefer lighter switches for extended typing sessions, as they can reduce fatigue and strain. This is particularly beneficial for those who use their keyboards for work or engage in long gaming sessions. On the other hand, individuals who value a more substantial typing experience may opt for switches with heavier forces.
In summary, while specific information about the actuation force of the Polaris Purple is unavailable, comparing it to the TTC Speed Silver reveals that the Speed Silver has a lighter actuation force and a lighter bottom out force. This means that the Speed Silver may be more suitable for those seeking a lighter typing experience, while the Polaris Purple may be preferred by individuals who desire a heavier and more substantial typing feel.
Travel distance
The SP-Star Polaris Purple tactile switch has a travel distance of 4 mm, which is considered the more traditional length for switch travel distance. On the other hand, the TTC Speed Silver linear switch has a slightly shorter travel distance of 3.4 mm. This makes the Speed Silver switch a good option for gamers who prioritize faster response times, as the shorter travel distance allows for quicker key presses. However, some individuals may find the shorter travel distance to feel too abrupt, preferring a switch with a deeper travel distance like the Polaris Purple. Ultimately, the choice between the two switches depends on personal preference and the desired level of responsiveness.
