TKC Kiwi vs. SP-Star RedBlue
An in-depth look at the TKC Kiwi and the SP-Star RedBlue switches—which one is the best fit for you?
Overview
When it comes to choosing the perfect mechanical keyboard switch, the TKC Kiwi and the SP-Star RedBlue are two popular options with distinct characteristics. The TKC Kiwi is a tactile switch that aims to enhance your typing experience with a medium to medium-strong bump at the top of each key press. Known for its satisfyingly snappy sound profile, the Kiwi delivers an immersive typing experience. Furthermore, it comes lightly factory lubed, ensuring a smooth and effortless typing experience right out of the box. On the other hand, the SP-Star RedBlue is a linear switch offering a medium-light typing experience. With a higher-pitched sound profile, it caters to those who prefer a different auditory feedback. However, let's dive in a bit deeper beyond generalities so you can best decide on the ideal switch for your needs.

Housing materials
The TKC Kiwi and the SP-Star RedBlue differ in their housing materials, with the Kiwi featuring a UHWMPE top housing and bottom housing, while the RedBlue utilizes a polycarbonate top housing and bottom housing. The UHWMPE top housing of the Kiwi offers a bright sound signature with resonant clacks when typing, providing a unique auditory experience. On the other hand, the polycarbonate top housing of the RedBlue creates a sharper, higher-pitched, and crisper sound profile. Aesthetically, the polycarbonate top housing is translucent, making it ideal for use with RGB lighting if desired.
Similarly, the bottom housings of the two switches differ, with the Kiwi having a UHWMPE bottom housing and the RedBlue utilizing a polycarbonate bottom housing. The UHWMPE bottom housing of the Kiwi contributes to the bright sound signature, resulting in resonant clacks when typing. In contrast, the polycarbonate bottom housing of the RedBlue creates a sharper, higher-pitched, and crisper sound profile. Additionally, the translucent nature of the polycarbonate bottom housing complements the aesthetics of the switch, especially when RGB lighting is incorporated.
It is important to note that when a switch has different top and bottom housings, the qualities brought by each housing material impact different aspects of typing. Pressing down on the switch will reveal the qualities of the bottom housing, affecting the bottom-out sound and feel experienced when typing. Conversely, the top housing's characteristics play a more prominent role in the sound generated when releasing a key. Although the TKC Kiwi and the SP-Star RedBlue use different housing materials, both switches offer distinctive sound profiles and tactile experiences, ensuring a satisfying typing experience.
Weight
When comparing the actuation force and bottom out force of the TKC Kiwi tactile switch and the SP-Star RedBlue linear switch, it is evident that the Kiwi switch is the heavier of the two. The Kiwi has an actuation force of 43 grams, indicating the amount of force required to trigger a keystroke, while the RedBlue's actuation force is unknown. In terms of bottom out force, the Kiwi requires 67 grams, signifying the force needed to press all the way down, while the RedBlue requires 57 grams.
Considering weight, individuals with a preference for lighter switches may opt for the RedBlue, as it has a medium-light bottom out force. This lighter weight allows for comfortable typing over extended periods, making it ideal for professional use or long gaming sessions. On the other hand, those who desire a stronger push feel and a more substantial typing experience may lean towards the Kiwi switch, as it has a medium-heavy bottom out force. This heavier force can provide a satisfying tactile feedback and a greater sense of control. Although the actuation force of the RedBlue switch is unavailable, it can be assumed that obtaining similar results as the Kiwi can be achieved by selecting a switch with properties similar to those of the Kiwi's actuation force. Ultimately, the choice between the two switches depends on individual preference and specific requirements for typing or gaming.
Travel distance
The TKC Kiwi tactile switch and the SP-Star RedBlue linear switch have the same travel distance of 4 mm, meaning they both travel a distance of 4 mm from the top to the bottom. When pressing down on a key equipped with either switch, users will experience a similar feeling of travel distance. Therefore, the length of travel for both switches is equal.

The sound of the Kiwi switch is also described as neutral, meaning it has a moderate actuation force requirement and a moderate sound profile suitable for various purposes. On the other hand, the SP-Star RedBlue linear switch also has a low-pitched sound profile, similar to the Kiwi switch. It is described as neutral as well, making it suitable for most intents and purposes. Additionally, the RedBlue switch is described as thocky, producing a deep, rich, and satisfying sound when pressed. Overall, both switches share similar qualities in terms of sound, with the RedBlue switch having the added thocky characteristic.
In terms of feel, the TKC Kiwi tactile switch provides a stepped feel. This means that the switch has two stages, with some pre-travel and/or post-travel. It is also described as accented, providing a medium amount of tactility that is neither overwhelming nor subtle. Additionally, the Kiwi switch is polished, resulting in a smooth and refined typing experience. The polished finish reduces friction and ensures smooth key travel. On the other hand, the SP-Star RedBlue linear switch offers a mild feel, providing a more gentle typing experience compared to switches with more pronounced characteristics. Similar to the Kiwi switch, the RedBlue switch is also polished, resulting in a sleek typing experience with reduced friction and smooth key travel.
Overall, both the TKC Kiwi tactile switch and the SP-Star RedBlue linear switch offer unique qualities in terms of sound and feel.
