TKC Kiwi vs. TTC Neptune
An in-depth look at the TKC Kiwi and the TTC Neptune switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the choice between a tactile switch like the TKC Kiwi and a linear switch like the TTC Neptune can be a tough decision. The Kiwi is praised for its medium-strong bump at the top of each key press, offering a satisfyingly snappy sound profile and a smooth typing experience right out of the box. On the other hand, the Neptune stands out with its innovative internal structure that provides a smooth, almost frictionless glide and a unique "matte" feel reminiscent of chewy delights like mochi or tapioca pearls. While the Kiwi focuses on enhancing the typing experience with a tactile bump, the Neptune emphasizes swift and effortless typing with a muted sound signature. 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 TKC Kiwi and the TTC Neptune differ in terms of their sound signatures and overall feel. The Kiwi's UHWMPE top and bottom housings offer a very bright sound with resonant clacks, while the Neptune's POM top and polycarbonate bottom housings create a deeper, more muted sound profile. The UHWMPE material provides a unique sound experience when typing, compared to the more traditional sound produced by POM and polycarbonate materials. In terms of aesthetics, the Neptune's polycarbonate bottom housing allows for RGB lighting to shine through, adding a visually appealing element to the switch.
While the top housings of the Kiwi and Neptune switches offer distinct sound profiles, the bottom housings also play a significant role in determining the overall sound and feel of the switches. The UHWMPE bottom housing of the Kiwi contributes to the bright and resonant sound when bottoming out keys, while the polycarbonate bottom housing of the Neptune enhances the sharper, crisper sound profile of the switch. This difference in bottom housing material highlights how the choice of materials can influence the overall typing experience, from key press to key release. Additionally, the translucency of polycarbonate in the Neptune switch allows for RGB lighting to create a visually appealing effect that is not present in the Kiwi.
In conclusion, the housing materials of the TKC Kiwi and the TTC Neptune offer unique characteristics that cater to different preferences in typing sound and feel. The UHWMPE top housing of the Kiwi provides a bright and resonant sound signature, while the POM top housing of the Neptune offers a deeper and more muted sound experience. Similarly, the bottom housings of the Kiwi and Neptune switches contribute to the overall sound profiles, with UHWMPE providing impact on bottom-out sound and feel, and polycarbonate enhancing the sharper, crisper quality of the switch. Ultimately, the choice between these housing materials depends on individual preferences for sound, feel, and aesthetics in mechanical keyboard switches.
Weight
When comparing the actuation force and bottom out force of the TKC Kiwi tactile switch and the TTC Neptune linear switch, it is evident that the Kiwi is heavier in both aspects. The Kiwi has an actuation force of 43 grams and a bottom out force of 67 grams, whereas the Neptune has an actuation force of 41 grams and a bottom out force of 50 grams. This means that the Kiwi requires a stronger push to trigger a keystroke and to bottom out compared to the Neptune. Those who prefer a more substantial typing experience may opt for the Kiwi, while those who prioritize lighter weight for longer typing sessions may prefer the Neptune. Ultimately, the choice between the two switches will depend on individual preferences for actuation and bottom out forces.
Travel distance
The TKC Kiwi tactile switch has a travel distance of 4mm, while the TTC Neptune linear switch has a slightly shorter travel distance of 3.8mm. Both switches fall within the range of traditional travel distances for mechanical switches, with the Kiwi being on the longer side and the Neptune being on the shorter side. The Kiwi's 4mm travel distance may provide a more substantial feel when typing, which could be preferred by some users. On the other hand, the Neptune's 3.8mm travel distance may offer a quicker and more responsive typing experience, which could be advantageous for gamers or those who prefer a shorter keypress distance. Ultimately, the choice between the two switches will depend on personal preference for typing feel and responsiveness.

Typing experience
In terms of sound, the TKC Kiwi tactile switch is known for its low-pitched and neutral sound profile, which provides a mellow tone that is suitable for various typing environments. On the other hand, the TTC Neptune linear switch also offers a low-pitched sound with muted, subdued, and thocky characteristics, creating a softer and more refined auditory experience. Both switches have a neutral sound profile, making them versatile options for a wide range of users. The choice between these two switches ultimately comes down to personal preference in sound profile, with the Kiwi offering a slightly more traditional typing sound while the Neptune provides a more subdued and textured experience.
In terms of feel, the TKC Kiwi tactile switch provides a stepped and accented typing experience, offering a medium to medium-strong bump with a polished finish for smooth key travel. Conversely, the TTC Neptune linear switch delivers a buttery and frictionless feel, with gummy and mild characteristics that ensure a seamless and effortless typing sensation. Both switches are polished for reduced friction and a sleek typing experience, offering comfortable typing for users of varying preferences. The decision between these two switches will depend on whether a user prefers a more pronounced tactile bump (Kiwi) or a smoother linear glide (Neptune).
Overall, the TKC Kiwi tactile switch and the TTC Neptune linear switch offer unique qualities in terms of sound and feel. The Kiwi provides a satisfyingly snappy sound profile with a medium-strong bump, while the Neptune offers a harmonious balance of smooth typing and springy resistance. Both switches are factory lubed for a smooth typing experience, making them ideal choices for users looking for a tactile or linear typing feel. Ultimately, the decision between these switches will come down to personal preference in sound, feel, and typing style, ensuring that users can find the perfect match for their mechanical keyboard needs.
Conclusion
In closing, when deciding between the TKC Kiwi tactile switch and the TTC Neptune linear switch, consider your preference for bottom out force, sound profile, and typing feel. If you prefer a slightly heavier bottom out force and a tactile typing experience with a satisfying bump, the Kiwi switch may be the right choice for you. On the other hand, if you prefer a lighter bottom out force and a smooth, almost frictionless typing experience with a unique matte feel, the Neptune switch could be more suitable. Additionally, if you prefer a low-pitched and neutral sound profile, the Kiwi switch may appeal to you, while the Neptune switch offers a low-pitched and muted sound experience. Ultimately, both switches have their unique characteristics, so choosing between them will depend on your personal preferences for typing feel, sound, and force requirements.
