Housing materials
The Gateron CM and KTT Purple Star both offer unique housing materials that contribute to the overall sound profile of the switches. The Gateron CM features a nylon top housing, which creates a deeper and fuller sound profile due to its soft nature that absorbs more sound. In contrast, the Purple Star utilizes a POM top housing, which also produces a deeper sound but with a more muted quality. While both housing materials result in a similar deeper sound, the Nylon top housing of the CM may offer a slightly rounder sound compared to the more muted sound of the POM top housing of the Purple Star.
Moving on to the bottom housing, the Gateron CM and KTT Purple Star once again showcase their differences in housing materials. The CM utilizes a nylon bottom housing, which contributes to the deeper and fuller sound profile of the switch due to its softer nature and sound absorbency. On the other hand, the Purple Star features a POM bottom housing, which also creates a pleasing and unique sound that is deeper and relatively more muted. While both bottom housings have similar qualities in terms of sound profile, the nylon housing of the CM may result in a slightly duller and rounder sound compared to the POM housing of the Purple Star.
Overall, the choice between the Gateron CM and KTT Purple Star will ultimately come down to personal preference in terms of sound profile. Both switches offer deep and pleasing sound profiles, with the Gateron CM's nylon housing providing a potentially rounder and fuller sound compared to the more muted sound of the Purple Star's POM housing. Whether you prefer a slightly duller sound with more impact on the bottom-out feel, or a more muted sound with a unique quality, both switches offer a high-quality typing experience with their respective housing materials.
Weight
When comparing the Gateron CM linear switch and the KTT Purple Star linear switch, one noticeable difference is in their actuation and bottom out forces. The Gateron CM has a higher actuation force of 55 grams compared to the KTT Purple Star's lighter 43 grams. Additionally, the Gateron CM requires a higher bottom out force of 63.5 grams, while the KTT Purple Star has a lighter bottom out force of 50 grams. This means that the Gateron CM switch provides a medium-heavy typing experience, requiring more force to actuate and bottom out, while the KTT Purple Star switch offers a lighter touch for quicker keystrokes. The choice between the two would depend on personal preference, with some preferring the lighter touch of the KTT Purple Star for longer typing sessions, while others may prefer the more substantial feel of the Gateron CM for a more pronounced typing experience. Ultimately, the weight of the actuation and bottom out forces will play a significant role in determining which switch is the better fit for each user.
