SP-Star Polaris Purple vs. KTT Semi Mute

An in-depth look at the SP-Star Polaris Purple and the KTT Semi Mute switches—which one is the best fit for you?

Overview

When it comes to mechanical keyboard switches, two popular options to consider are the SP-Star Polaris Purple and the KTT Semi Mute. While both switches offer their own unique features and benefits, they cater to different preferences and needs. The Polaris Purple is a tactile switch and is best known for its exhilarating tactile typing experience, thanks to its big tactile bump. Additionally, its snappy sound profile adds to the overall satisfaction of using this switch. On the other hand, the Semi Mute is a linear switch and is named as such despite its completely silent operation. This switch is ideal for those who prioritize a noise-free environment and undisturbed typing, particularly during late-night sessions. With its linear actuation and advanced dampening technology, the KTT Semi Mute delivers a comfortable and gratifying typing feel. However, let's dive in a bit deeper beyond these generalities so you can best decide on the switch that suits your preferences.

Housing materials

The housing materials used in the SP-Star Polaris Purple and the KTT Semi Mute switches are both made of polycarbonate. Polycarbonate is known for creating a sharper, higher-pitched, and crisper sound profile due to its relatively stiffer property. This translates to a more clear and resonant sound experience when typing on these keyboards. Additionally, both switches feature a clear housing, which is typical for polycarbonate material, making them suitable for RGB lighting enthusiasts.

While both switches share similar housing materials and their benefits, the key difference lies in how these materials are distributed within the switch. In the Polaris Purple, the polycarbonate top housing primarily affects the sound when the key is released, creating a distinct auditory experience. On the other hand, the polycarbonate bottom housing in the Polaris Purple influences the bottom-out sound and feel when the key is pressed down. This division of qualities between the top and bottom housings contributes to a well-rounded typing experience.

Similarly, in the case of the KTT Semi Mute, the polycarbonate top housing and bottom housing play distinct roles. The top housing impacts the sound upon key release, while the polycarbonate bottom housing affects the bottom-out sound and feel. The allocation of these housing materials allows for a tailored typing experience, ensuring a satisfying auditory response through the entire key press.

In summary, both the SP-Star Polaris Purple and the KTT Semi Mute utilize polycarbonate housing materials in their top and bottom housings, resulting in a similar overall sound profile. However, the allocation of these materials within the switches enables them to deliver differing auditory experiences during key press and release. Whether you prefer a more pronounced sound upon release or a satisfying bottom-out sensation, both switches offer unique benefits that cater to individual typing preferences.

Weight

When comparing the actuation force and bottom out force of the SP-Star Polaris Purple tactile switch and the KTT Semi Mute linear switch, there are notable differences. The Polaris Purple's actuation force is unavailable, making it difficult to directly compare to the Semi Mute's force of 43 grams. However, in terms of bottom out force, the Polaris Purple comes in at a heavier 67 grams, while the Semi Mute sits at a lighter 58 grams. This makes the Polaris Purple switch better suited for those seeking a stronger push feel and a more substantial typing experience, as the heavier bottom out force provides a satisfying tactile feedback. On the other hand, the Semi Mute switch offers a lighter actuation and bottom out force, which may be preferable for users who value a lighter typing experience, particularly for longer typing sessions or extended gaming sessions. Despite not having the specific actuation force for the Polaris Purple, it can be inferred that it likely requires a stronger push to trigger a keystroke, taking into account its heavier bottom out force compared to the Semi Mute. Therefore, both switches offer distinct options for users depending on their preferences and desired typing experience.

Travel distance

The travel distance of a switch is the amount of distance it covers from the top of the switch to the bottom when it is pressed down. Both the SP-Star Polaris Purple tactile switch and the KTT Semi Mute linear switch have a travel distance of 4 mm. This means that when you press down on the keys equipped with either of these switches, you will feel a similar distance traveled by the switch. Therefore, both switches offer a consistent and matching travel distance.

Typing experience

When it comes to sound, the SP-Star Polaris Purple and the KTT Semi Mute switches offer different profiles. The Polaris Purple is described as having a "snappy" sound profile. This means that it produces a distinctive and crisp sound during typing. On the other hand, the Semi Mute switches are specifically designed for a noise-free environment. Despite being named "Semi Mute," these switches are completely silent in operation. They fall under the category of "muted" switches, which means they produce a softer and quieter sound compared to regular switches. So, if you prefer a more noticeable and exhilarating typing sound, the Polaris Purple would be a better choice. However, if you value a quiet and undisturbed typing experience, the KTT Semi Mute switches are ideal.

In terms of feel, the Polaris Purple switches offer a mild tactile typing experience. This means that they have a gentle and approachable feel without being too pronounced. Combined with their "polished" finish, which results in a smooth and refined typing experience, these switches provide reduced friction and smooth key travel. On the other hand, the KTT Semi Mute switches are described as feeling "buttery." This implies a smooth and fluid keystroke experience, providing a seamless and effortless typing sensation. Additionally, like the Polaris Purple, they also fall under the category of mild switch, ensuring a comfortable and gratifying typing feel. So, if you prefer a switch with a more gentle and refined feel, the Polaris Purple would be a good choice. Conversely, if you seek a smooth and effortless typing sensation, the KTT Semi Mute switches are a suitable option.

In conclusion, the SP-Star Polaris Purple and the KTT Semi Mute switches offer distinct qualities in terms of sound and feel. The Polaris Purple stands out with its exhilarating tactile typing experience, providing a snappy sound profile and a mild typing feel with a polished finish. On the other hand, the KTT Semi Mute switches prioritize a noise-free environment, offering completely silent operation and a buttery, fluid typing experience with a mild feel. Ultimately, the choice between the two will depend on personal preferences. If you prioritize a distinctive and crisp typing sound with a refined feel, go for the Polaris Purple. However, if a quiet and seamless typing experience is more important, opt for the KTT Semi Mute switches. Regardless of the choice, both switches are suitable for most intents and purposes, making them accessible to beginners and experts alike.

Conclusion

To sum up, if you are looking for a tactile switch with a satisfying bump and a snappy sound profile, the SP-Star Polaris Purple would be a great choice. With a bottom out force of 67 grams, it provides a medium-heavy typing experience that can be suitable for both beginners and advanced users. On the other hand, if you prioritize a noise-free environment and want a switch with a comfortable and gratifying typing feel, especially during late-night sessions, the KTT Semi Mute linear switch is the way to go. With a bottom out force of 58 grams, it offers a medium typing experience and operates silently despite its name. These switches have advanced dampening technology, providing a smooth and fluid keystroke experience. Ultimately, the decision between the SP-Star Polaris Purple and the KTT Semi Mute linear switch depends on your preference for a tactile typing experience with a snappy sound or a noise-free environment with a comfortable and buttery typing feel.
