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

Overview

The KTT Grapefruit and the SP-Star Polaris Purple are two distinct mechanical keyboard switches with unique qualities and characteristics. The KTT Grapefruit is a linear switch, known for its soft and light feel, offering a smooth typing experience. With a "baritone" sound profile that is not yet "bass" deep, the Grapefruit provides a unique auditory experience. On the other hand, the SP-Star Polaris Purple is a tactile switch, featuring a big tactile bump that delivers an exhilarating typing experience. This switch offers a snappy sound profile. While both switches fall under the "Polished" category and share a "Neutral" switch feel, they differ in terms of pitch and intensity. The Grapefruit is low-pitched and has a more subdued feel, while the Polaris Purple has a mild intensity. These general features may help guide your decision, but let's dive in a bit deeper beyond these generalities so you can best decide on the perfect switch for your needs.

Housing materials

The KTT Grapefruit and the SP-Star Polaris Purple both utilize polycarbonate as their top housing material. This choice results in a sharper, higher-pitched, and crisper sound profile for both switches. The stiffness of polycarbonate enhances the clarity and resonance of the sound. Additionally, the translucency of polycarbonate makes it ideal for switches that plan to incorporate RGB lighting. Therefore, users can expect similar results in terms of sound and aesthetics from both the Grapefruit and the Polaris Purple's top housings.

However, while the Grapefruit features a nylon bottom housing, the Polaris Purple utilizes a polycarbonate bottom housing. This difference in material leads to variations in sound profiles. The Grapefruit's nylon bottom housing creates a deeper and fuller sound when typing, thanks to its relatively softer plastic that absorbs more sound. On the other hand, the Polaris Purple's polycarbonate bottom housing contributes to a sharper, higher-pitched, and crisper sound. The bottom housing has a bigger impact on the bottom-out sound and feel, providing a different tactile experience between the two switches.

In summary, the polycarbonate top housing of the KTT Grapefruit and the SP-Star Polaris Purple provides them with similar sound profiles, characterized by sharpness, high-pitches, and crispness. However, the choice of housing material for their bottom housings creates differences in sound and feel. The Grapefruit's nylon bottom housing offers a deeper and fuller sound, while the Polaris Purple's polycarbonate bottom housing adds to the sharp and crisp sound. These variations make each switch unique in its tactile experience.

Weight

When comparing the actuation force and bottom out force of the KTT Grapefruit linear switch and the SP-Star Polaris Purple tactile switch, there are some notable differences. The Grapefruit has an actuation force of 45 grams, providing a medium-light feel, while the Polaris Purple's actuation force is unknown. In terms of bottom out force, the Grapefruit requires 53 grams to fully depress the key, which also falls under the medium-light category. On the other hand, the Polaris Purple has a bottom out force of 67 grams, making it medium-heavy.

For those who prefer a lighter typing experience, the Grapefruit switch would be a suitable choice. Its lower actuation and bottom out forces allow for longer typing sessions without excessive fatigue. Conversely, individuals seeking a more substantial push feel might prefer the Polaris Purple switch due to its heavier bottom out force. The unknown actuation force of the Polaris Purple switch makes it difficult to draw a direct comparison, but it is likely to require more force than the Grapefruit.

Overall, whether one prefers the lighter actuation and bottom out forces of the Grapefruit or the heavier bottom out force of the Polaris Purple, weight is an important consideration. Choosing a switch with a force that aligns with personal preferences can enhance both work efficiency and gaming performance, ensuring a comfortable and satisfying typing experience.

Travel distance

Both the KTT Grapefruit linear switch and the SP-Star Polaris Purple tactile switch have a similar travel distance of 4 mm. This means that when you press down on a key, you will feel the same distance travel for both switches. Therefore, whether you choose the Grapefruit or the Polaris Purple, you can expect similar results in terms of the distance the switch travels from the top to the bottom.
