Cherry MX Purple RGB vs. KTT Purple Star
An in-depth look at the Cherry MX Purple RGB and the KTT Purple Star switches—which one is the best fit for you?
Overview
When it comes to the tactile and linear dynamics of mechanical keyboard switches, the Cherry MX Purple RGB and the KTT Purple Star stand out for distinct reasons tailored to different user preferences. The Cherry MX Purple RGB switches are celebrated for their refined tactile feedback, providing a satisfying medium-strength bump that enhances the typing experience with each keystroke. This makes it particularly appealing for those who enjoy a tactile response while typing, giving a reassuring confirmation that the key has been actuated. In contrast, the KTT Purple Star switches offer a smooth and linear typing experience, thanks to their all-POM construction and very light 45g actuation force. This makes them a preferred choice for light typists seeking effortless keystrokes without the interruption of tactile feedback. While both switches cater to diverse typing styles—whether one seeks a more engaging and tactile experience or a fluid and quiet operation—each brings unique benefits to the table. 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 Cherry MX Purple RGB and the KTT Purple Star switches showcase distinctive characteristics that influence their overall sound profiles. The Cherry MX Purple RGB features both a nylon top and bottom housing, contributing to a consistent and cohesive auditory experience. Nylon, being a softer plastic, absorbs sound more effectively than harder plastics, which results in a deeper and fuller sound profile. This quality makes the typing experience on these switches feel rounded and rich. In contrast, the KTT Purple Star switches utilize POM (Polyoxymethylene) for both their top and bottom housings, which creates a unique auditory profile that is also muted and deeper. While both switch designs aim for a satisfying sound experience, the materials employed lead to different auditory nuances that typists and gamers may prefer based on their personal tastes.
While the MX Purple RGB and KTT Purple Star both aim to deliver sound profiles that are pleasing to the ear, the differences in materials result in distinct typing experiences. The nylon housing of the MX Purple RGB provides a traditional and time-tested feel with a fuller resonance during key release and bottoming out. In contrast, the POM housing of the KTT Purple Star offers a slightly different feel, with a focus on producing a muted sound that still retains a depth characteristic. This variance in material leads to differences in resonance, where the Cherry MX version emphasizes a more classic sound experience while the KTT’s POM composition results in a unique, softer response, catering to users who may prefer a quieter gameplay or typing experience.
Importantly, despite these differences, users could achieve a somewhat similar typing experience with both switches due to the shared goal of creating a deeper sound profile. Although the materials differ, both the Nylon and POM housings contribute to a rounded sonic quality which can appeal to users looking for a nice sound without harsh overtones. Ultimately, the decision between the Cherry MX Purple RGB and KTT Purple Star will hinge on individual preferences regarding feel, sound profile, and aesthetics, as well as the importance placed on the specific auditory characteristics that each material delivers during use.
Weight
When comparing the Cherry MX Purple RGB tactile switch and the KTT Purple Star linear switch, there are notable differences in their actuation force and bottom out force. The Cherry MX Purple RGB has an actuation force of 45 grams, while the KTT Purple Star features a slightly lighter actuation force of 43 grams. This means that typists who prefer a lighter touch will find the KTT Purple Star more comfortable for extended use, making it ideal for lengthy typing sessions or prolonged gaming marathons. However, the KTT Purple Star has a bottom out force of 50 grams, indicating a heavier feel when pushing the key all the way down. In contrast, the bottom out force for the Cherry MX Purple RGB is unknown, leaving a gap in the comparison. Thus, while both switches offer a difference in actuation force where the KTT Purple Star is lighter, the unknown bottom out force of the Cherry MX Purple RGB makes it difficult to determine their overall bottoming out sensation. Consequently, if one is looking for a more tactile and heavier feel, the Cherry MX might be favorable depending on its unknown bottom resting weight.
Travel distance
When comparing the travel distances of the Cherry MX Purple RGB tactile switch and the KTT Purple Star linear switch, a noticeable difference emerges. The Cherry MX Purple RGB features a travel distance of 4 mm, while the KTT Purple Star has a shorter travel distance of 3.5 mm. This makes the KTT Purple Star the shorter option, catering to gamers and users seeking a quicker and more responsive keypress. On the other hand, the Cherry MX Purple RGB, with its longer travel distance, may appeal to those who prefer a more substantial and traditional typing experience. Therefore, if you enjoy the tactile feedback and depth of a longer travel, the Cherry MX Purple RGB would be the better choice, whereas the KTT Purple Star offers a snappier response for those who favor speed.

Typing experience
When it comes to sound, the Cherry MX Purple RGB switch has yet to be characterized, leaving a gap in understanding its auditory profile. In contrast, the KTT Purple Star switches are noted for their low-pitched sound, which gives them a more bass-heavy and mellow tone. This neutral sound signature tends to be less intrusive and more pleasant for extended typing sessions. Importantly, sound can also be influenced by the choice of keyboard, including aspects like the materials used in the board and the keycaps, which means that while the Purple Star tends to offer a more consistent auditory experience, the MX Purple RGB's sound could vary significantly based on different setups.
Regarding feel, the Cherry MX Purple RGB switch is recognized for its refined tactile experience featuring a short, medium-strength bump that provides a satisfying feedback during typing. Conversely, the KTT Purple Star switches are designed to deliver a mild experience characterized by gentle resistance and an easy-to-press action, requiring minimal force to activate. This results in a typing experience that feels both responsive and low-impact, making it ideal for users seeking comfort during extended sessions. While the tactile satisfaction of the MX Purple RGB may be preferable for those who enjoy a clear bump, the Purple Star offers a softer and more forgiving feel which can also be attractive to many typists.
In summary, both switches present unique qualities that cater to different preferences. The Cherry MX Purple RGB is highlighted for its tactile feedback, making it suitable for those who appreciate a defined bump while typing. In contrast, the KTT Purple Star excels in delivering a smooth and easy typing experience with a pleasant sound. Ultimately, your choice will depend on whether you prefer a tactile sensation or a gentler, more effortless typing experience.
Conclusion
To conclude, choosing between the Cherry MX Purple RGB tactile switches and the KTT Purple Star linear switches ultimately depends on your typing style and preferences. If you crave a tactile experience with a refined bump that provides feedback while typing, especially for tasks like coding or gaming where precision matters, the Cherry MX Purple RGB is the ideal choice. Its thoughtfully designed tactile feedback caters to those who appreciate a more engaged typing experience. On the other hand, if you prefer an effortlessly smooth and quiet typing experience, or if you are a light typist looking to minimize finger fatigue during long typing sessions, the KTT Purple Star should be your go-to. Its low resistance and gentle activation make it perfect for fast and comfortable typing without the distraction of pronounced feedback. In essence, if you want a combination of tactile feedback and a robust build, go for the MX Purple RGB. Conversely, if you prioritize a silky smooth feel and ease of use, especially in quieter environments, the KTT Purple Star will serve you well.
