KTT Purple Star vs. Kailh Sage
An in-depth look at the KTT Purple Star and the Kailh Sage switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, two popular options to explore are the KTT Purple Star linear switch and the Kailh Sage clicky switch. The Purple Star switches are praised for their all-POM construction, providing a smooth typing experience with a neutral sound signature. With a light 45g bottom-out force, they are well-suited for light typists seeking ease and comfort while typing. On the other hand, the Kailh Sage switches offer a distinct clicky typing experience with a heavier weight and sharp clickiness. While the Purple Star switch is categorized as 'Mild', 'Low-pitched', and 'Easy-to-press', the Sage switch is characterized as 'Invigorating', 'Sharp', and 'Crunchy'. Both switches have their own unique qualities that cater to different preferences. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
One key difference between the housing materials of the KTT Purple Star and the Kailh Sage is that the Purple Star utilizes POM for both the top and bottom housings, resulting in a deeper and more muted sound profile overall. In contrast, the Sage uses polycarbonate for the top housing, creating a sharper, higher-pitched sound when keys are released, while utilizing nylon for the bottom housing, which produces a deeper and fuller sound when keys are pressed. This difference in housing materials gives each switch a unique sound profile that caters to different preferences.
Additionally, the aesthetic aspect of the housing materials sets the Purple Star and the Sage apart. With the Purple Star featuring a POM top housing, it may not be as visually striking as the Sage, which utilizes a polycarbonate top housing. The translucency of polycarbonate allows for RGB lighting to shine through, giving the Sage a more vibrant appearance. This difference in appearance may be a deciding factor for users who value the visual aspect of their mechanical keyboards.
Despite the differences in housing materials between the Purple Star and the Sage, both switches aim to create a pleasing and unique typing experience. While the POM housing of the Purple Star produces a deeper sound profile, the combination of polycarbonate and nylon in the Sage offers a mix of high-pitched and fuller sounds. Ultimately, the choice between these two switches may come down to personal preference in terms of sound, feel, and aesthetics. Both switches offer quality construction and innovative design to enhance the typing experience for mechanical keyboard enthusiasts.
Weight
The KTT Purple Star linear switch has a lighter actuation force of 43 grams compared to the Kailh Sage clicky switch, which has an unknown actuation force. However, the Purple Star has a slightly heavier bottom out force of 50 grams, while the Sage has a bottom out force of 70 grams, making it medium-heavy. The difference in actuation force may result in a softer typing experience with the Purple Star, while the Sage may provide a more substantial and tactile typing feel. Depending on personal preference, some may appreciate the lighter actuation force of the Purple Star for longer typing sessions, while others may prefer the heavier push of the Sage for a more satisfying keystroke sensation. Ultimately, the choice between the two switches will depend on individual typing preferences and the desired typing experience.
Travel distance
In comparing the travel distance of the KTT Purple Star linear switch and the Kailh Sage clicky switch, we find that the Purple Star has a travel distance of 3.5 mm, while the Sage has a travel distance of 3.6 mm. Both switches fall within the range of shorter travel distances, which are becoming increasingly popular, especially among gamers seeking faster response times. Choosing a switch with a shorter travel distance, such as the Purple Star, can provide a more responsive typing experience. However, for those who prefer a more substantial keypress, the slightly longer travel distance of the Sage may be more appealing. Ultimately, the choice between the two switches will come down to personal preference for keypress feel and response time.
