Housing materials
In comparing the housing materials of the KTT Purple Star and the SP-Star RedBlue, it is evident that both switches utilize different materials for their top and bottom housings. The Purple Star features POM for both the top and bottom housing, creating a deep and muted sound profile. In contrast, the RedBlue utilizes polycarbonate for both the top and bottom housing, resulting in a sharper, higher-pitched, and crisper sound profile. While the Purple Star's POM housing provides a unique sound experience, the RedBlue's polycarbonate housing is known for its clarity and resonance.
Despite the differences in housing materials between the two switches, both the Purple Star and RedBlue share similarities in their approach to offering a unique sound experience. The use of POM in the Purple Star's housing creates a distinct sound profile, while the polycarbonate housing of the RedBlue enhances the sound clarity and resonance. Additionally, both switches benefit from the translucency of their top housings, with polycarbonate being particularly useful for RGB lighting effects. Overall, both switches prioritize sound quality and aesthetics in their housing materials.
Ultimately, the choice between the KTT Purple Star and the SP-Star RedBlue comes down to personal preference in sound profile and aesthetic preferences. While the Purple Star's POM housing creates a deep and muted sound, the RedBlue's polycarbonate housing delivers a sharper and crisper sound. Additionally, the translucency of the polycarbonate housing in the RedBlue adds a visual appeal, especially when paired with RGB lighting. Both switches offer a unique sound experience, with the housing materials playing a significant role in shaping the overall sound profile of each switch.
Weight
When comparing the actuation force and bottom out force of the KTT Purple Star linear switch and the SP-Star RedBlue linear switch, there are notable differences. The Purple Star has a lighter actuation force of 43 grams compared to the RedBlue, which has an unknown actuation force. However, the RedBlue has a heavier bottom out force of 57 grams compared to the Purple Star's 50 grams. This means that the Purple Star is lighter in terms of both actuation and bottom out forces, making it suitable for those who prefer a lighter typing experience.
