TKC Kiwi vs. HMX Xinhai
An in-depth look at the TKC Kiwi and the HMX Xinhai switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, the TKC Kiwi, a tactile switch, and the HMX Xinhai, a linear switch, stand out as popular choices. The Kiwi switches are well-known for their medium to medium-strong bump at the top of each key press, providing a satisfyingly snappy sound profile and a truly immersive typing experience. On the other hand, the Xinhai switches offer a unique acoustics profile with a softer sound thanks to the PA12 top housing and a distinctively crisp, higher-pitched resonance from the POM stem. Each switch has its own qualities that make it appealing - the Kiwi for its smooth and effortless typing experience out of the box, and the Xinhai for its blend of sophistication and performance. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The TKC Kiwi and the HMX Xinhai both offer unique housing materials for their switches. The Kiwi features UHWMPE top and bottom housings, providing a bright and resonant sound signature when typing. In contrast, the Xinhai utilizes polycarbonate for its top housing, creating a sharper and crisper sound profile. While UHWMPE is newer and offers a bright sound, polycarbonate is known for its stiffer properties and clear resonant sound. Though different in material, both housings aim to enhance the typing experience with their distinct sound qualities.
Furthermore, the bottom housing of the Kiwi is also UHWMPE, emphasizing the bright and resonant sound signature of the switch. On the other hand, the Xinhai features a nylon bottom housing, which elicits a deeper and fuller sound profile due to its softer properties. The difference in bottom housing material showcases how the switch can produce varying sound profiles based on the type of material used. Whether it's the bright sound of UHWMPE or the deeper tones of nylon, both bottom housings contribute to the overall sound experience of the switch.
It's important to note that the qualities of the housing material are split between the top and bottom of the switch. The bottom housing has a significant impact on the bottom-out sound and feel when typing, while the top housing influences the sound when releasing a key. While the Kiwi and Xinhai utilize different housing materials for their top and bottom housings, they both aim to enhance the typing experience with their unique sound profiles. Whether it's the bright and resonant UHWMPE of the Kiwi or the sharp and crisp polycarbonate of the Xinhai, each housing material brings its own qualities to the switch.
Weight
The actuation force and bottom out force of the TKC Kiwi tactile switch and the HMX Xinhai linear switch differ significantly. The Kiwi has a medium-heavy actuation force of 43 grams and a bottom out force of 67 grams, providing a substantial typing experience. In contrast, the Xinhai has a lighter actuation force of 37 grams and a bottom out force of 45 grams, making it better suited for extended typing sessions. The Kiwi is heavier compared to the Xinhai, which is lighter, appealing to different preferences. For those who prefer a lighter typing experience for longer durations, the Xinhai would be the better choice. On the other hand, if a more pronounced keystroke feel is desired, the Kiwi would be more suitable. Ultimately, the choice between these two switches would depend on individual typing preferences.
Travel distance
In comparing the travel distance of the TKC Kiwi tactile switch and the HMX Xinhai linear switch, it is clear that the Kiwi has a longer travel distance of 4 mm compared to the Xinhai's shorter 3.4 mm travel distance. The Kiwi's 4.0mm travel distance offers a more traditional feel, while the Xinhai's 3.4mm travel distance provides a shallower press. Gamers may prefer the Xinhai for its faster response time due to the shorter travel distance, while those looking for a more substantial key press may opt for the Kiwi with its longer travel distance. Ultimately, the choice between the two switches will depend on individual preferences for key feel and responsiveness.

If you prefer a quieter and smoother typing experience, the Kiwi switch would be the better choice. However, if you enjoy a more crisp and percussive sound while typing, the Xinhai switch would be more suitable.
When it comes to feel, the TKC Kiwi switch provides a stepped and accented tactile experience, offering a medium-strong bump at the top of each key press. This gives a satisfying tactile feedback without being overwhelming. Additionally, the switch is polished, resulting in a smooth and refined typing experience. On the other hand, the HMX Xinhai switch is described as bouncy and creamy, providing a spring-like feedback with a smooth and buttery typing sensation. If you prefer a more pronounced tactile bump and a polished feel, the Kiwi switch would be ideal. However, if you enjoy a bouncy and creamy typing experience that is smooth and effortless, the Xinhai switch would be more suitable.
In conclusion, the TKC Kiwi and HMX Xinhai switches offer unique sound and feel characteristics that cater to different preferences. The Kiwi switch provides a low-pitched sound profile with a stepped, accented tactile feel, while the Xinhai switch offers a clacky sound with a bouncy, creamy feel. Depending on whether you prioritize sound or feel in your typing experience, you can choose the switch that best suits your preferences. Both switches are factory lubed, providing smooth key travel right out of the box, which ensures a satisfying typing experience regardless of your choice. Ultimately, the decision between the two switches comes down to personal preference and the type of typing experience you are looking to achieve.
Conclusion
In closing, when considering whether to choose the TKC Kiwi tactile switch or the HMX Xinhai linear switch, it really comes down to your personal preference and typing style. If you enjoy a medium to medium-strong bump with a satisfyingly snappy sound profile, then the Kiwi switch is the way to go. On the other hand, if you prefer a lighter touch with a unique PA12 top housing for softer acoustics and a POM stem for a crisp, higher-pitched resonance, then the Xinhai switch may be more suitable for you. Ultimately, the decision between the Kiwi and Xinhai switches will depend on whether you prioritize a tactile typing experience or a smooth linear feel. Experimenting with both switches will ultimately help you determine which one aligns better with your typing preferences.
