Housing materials
When comparing the housing materials of the Outemu Tom and the KTT Purple Star, one notable difference is in their top housings. The Tom features a polycarbonate top housing, which produces a sharper, higher-pitched, and crisper sound profile due to its stiffness. On the other hand, the Purple Star has a POM top housing that creates a deeper and more muted sound profile. While both materials are known for their pleasing sound characteristics, the polycarbonate of the Tom leans towards a more clear and resonant sound, while the POM of the Purple Star offers a unique and deeper tone.
In terms of bottom housings, the Tom utilizes a nylon material that results in a deeper and fuller sound profile. Nylon, being a softer plastic, absorbs more sound and creates a duller and rounder sound compared to harder plastics. Similarly, the Purple Star also utilizes POM for its bottom housing, leading to a pleasing and unique sound profile that is on the deeper side and relatively more muted. Both housings contribute to the overall sound and feel of the switch, with the bottom housing impacting the bottom-out sound and feel, while the top housing influences the sound upon key release.
Overall, while the top and bottom housing materials of the Outemu Tom and KTT Purple Star differ, they each bring unique qualities to the switches' sound profiles. The polycarbonate and nylon of the Tom offer a sharper and crisper sound with a deeper and fuller bottom-out feel, while the POM of the Purple Star provides a pleasing and unique sound that is deeper and more muted. Both switches offer distinct sound characteristics based on their housing materials, catering to different preferences and styles of typing experience.
Weight
The Outemu Tom tactile switch has a heavier actuation force of 55 grams compared to the KTT Purple Star linear switch, which has a lighter actuation force of 43 grams. However, when it comes to bottom out force, the Purple Star requires 50 grams to fully press down, while the Tom's bottom out force is unknown. This means that the Purple Star switch offers a lighter typing experience overall. The actuation force is essential for determining the pressure needed to initiate a keystroke, while the bottom out force indicates the amount of pressure required to fully press the key. Ultimately, the choice between these two switches will depend on whether you prefer a lighter or heavier feel while typing.
Travel distance
The Outemu Tom tactile switch has a travel distance of 3.3 mm, while the KTT Purple Star linear switch has a travel distance of 3.5 mm. Both switches fall within the range of shorter travel distances, making them well-suited for quick and responsive typing or gaming experiences. The slight difference of 0.2 mm between the two may not be significant to most users, but those who are particularly sensitive to travel distances may notice a slightly deeper press with the Purple Star compared to the Tom switch. Ultimately, the choice between the two switches will depend on individual preferences for travel distance and typing feel.
