TTC Iron vs. TKC Kiwi
An in-depth look at the TTC Iron and the TKC Kiwi switches—which one is the best fit for you?
Overview
When choosing between mechanical keyboard switches, two popular options to consider are the TTC Iron and the TKC Kiwi. The TTC Iron is a linear switch known for its unique clacky sound signature and light actuation, offering a swift and fatigue-free typing experience with buttery smooth travel. On the other hand, the TKC Kiwi is a tactile switch designed to provide a medium to medium-strong bump at the top of each key press, enhancing the typing experience with a satisfyingly snappy sound profile. While the TTC Iron is best suited for those seeking precision and pleasure in every keystroke, the TKC Kiwi offers a smooth and effortless typing experience right out of the box. 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 TTC Iron and TKC Kiwi switches offer distinct sound profiles and tactile experiences. The Iron's POM top and bottom housings present a deep and muted sound, creating a satisfying typing experience that is more subtle in its auditory feedback. In contrast, the Kiwi's UHWMPE top and bottom housings deliver a bright and resonant sound, producing louder and crisper clacks while typing. This difference in sound signature between the two housing materials impacts the overall feel and acoustics of each switch, catering to different preferences for typing feedback.
Despite the contrasting sound profiles of the Iron and Kiwi housing materials, both switches offer unique qualities that contribute to an enjoyable typing experience. The POM housing of the Iron provides a pleasing and distinctive sound that is on the deeper side, while the UHWMPE housing of the Kiwi offers a brighter and more resonant acoustic experience. The differences in material properties between the two switches result in a varied tactile response and sound output, catering to the preferences of different users based on their desired typing feel and auditory feedback.
In terms of construction, the split between the top and bottom housing materials of the Iron and Kiwi switches plays a significant role in shaping the overall typing experience. The bottom housing material has a more pronounced impact on the bottom-out sound and feel of the switch, influencing the tactile feedback when pressing down on a key. On the other hand, the top housing material affects the sound produced when letting go of a key, adding to the overall sound profile of the switch. Despite these differences, both the Iron and Kiwi switches offer a unique combination of housing materials that contribute to a satisfying typing experience, albeit with distinct characteristics in sound and tactile feedback.
Weight
The TTC Iron linear switch has a lighter actuation force of 41 grams compared to the TKC Kiwi tactile switch with an actuation force of 43 grams. Both switches have similar actuation forces, so users can expect a comparable typing experience in that aspect. However, when it comes to bottom out force, the Iron requires 50 grams while the Kiwi needs 67 grams, making the Kiwi the heavier option. The lighter actuation force of the Iron may be preferred by individuals who value longer typing sessions without fatigue, such as for work or gaming purposes. Conversely, the heavier bottom out force of the Kiwi provides a more substantial typing experience for those who prefer a stronger push feel. Ultimately, the choice between the TTC Iron and the TKC Kiwi will depend on individual preference for actuation and bottom out forces.
Travel distance
When comparing the TTC Iron linear switch and the TKC Kiwi tactile switch, it is clear that the Iron has a shorter travel distance of 3.8 mm compared to the Kiwi which has a travel distance of 4 mm. Both fall within the range of traditional travel distances, with the Iron being slightly shorter. Gamers may prefer the Iron for its faster response time due to the shorter travel distance, while those who prefer a more substantial key press may opt for the Kiwi with its slightly longer travel distance. Ultimately, the choice between the two switches will depend on personal preference for key press depth and responsiveness.
