SP-Star RedBlue vs. KTT Sea Salt Lemon
An in-depth look at the SP-Star RedBlue and the KTT Sea Salt Lemon switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, two options that deserve attention are the SP-Star RedBlue and the KTT Sea Salt Lemon, both of which are linear switches. The RedBlue stands out for its medium-light typing experience, making it the ideal choice for those who prefer a gentler touch while typing. Additionally, this switch offers a higher-pitched sound profile, which may appeal to users seeking a slightly more vibrant auditory feedback. On the other hand, the Sea Salt Lemon is known for its smoothness, thanks to its progressive spring and KTT's dry-lube design. This combination results in a buttery typing experience that is sure to please even the most discerning typists. Both switches share similarities, such as being low-pitched, neutral, and mild in their typing feel. However, let's dive in a bit deeper beyond these generalities so you can best decide on the perfect switch for you.

Housing materials
The housing materials of the SP-Star RedBlue and the KTT Sea Salt Lemon switches share many similarities. Both switches feature a polycarbonate top housing, which creates a sharper, higher-pitched, and crisper sound profile. This is attributed to polycarbonate being a relatively stiffer plastic, resulting in a more clear and resonant sound. Additionally, the top housing's translucency makes it ideal for switches that utilize RGB lighting. Therefore, users can expect similar sound and aesthetic qualities from the polycarbonate top housings of both switches.
However, when it comes to the bottom housing, there is a notable difference. The RedBlue switch features a polycarbonate bottom housing, while the Sea Salt Lemon switch utilizes a nylon bottom housing. This divergence in materials leads to distinct sound profiles for each switch. The nylon bottom housing of the Sea Salt Lemon creates a deeper and fuller sound, as nylon is a softer plastic that absorbs more sound. On the other hand, the polycarbonate bottom housing of the RedBlue contributes to the bottom-out sound and feel, providing a different tactile experience compared to the Sea Salt Lemon.
It's important to note that the top and bottom housing materials play a significant role in the overall sound and feel of the switches. While the bottom housing affects the bottom-out sound and feel when pressing down on a key, the top housing influences the sound when releasing the key. Therefore, the qualities associated with each housing material will be divided between the top and bottom of the switches. As a result, users can expect nuanced differences in the sound and feel of the SP-Star RedBlue and the KTT Sea Salt Lemon, based on their respective housing materials.
Weight
When comparing the actuation force and bottom out force of the SP-Star RedBlue linear switch and the KTT Sea Salt Lemon linear switch, it is clear that both switches fall into the medium-light category. Although the exact actuation force of the RedBlue switch is unavailable, it can be assumed that it is similar to or falls within the range of the Sea Salt Lemon's actuation force of 45 grams. Similarly, the bottom out force of the RedBlue switch at 57 grams is slightly heavier than the Sea Salt Lemon's 53 grams.
Considering weight, some individuals prefer a lighter switch to increase typing endurance, making it suitable for extended typing sessions, work environments, or long gaming sessions. Both the RedBlue and Sea Salt Lemon switches fulfill this requirement by being in the medium-light range.
On the other hand, some users might seek a stronger push feel for a more substantial typing experience. These individuals can opt for switches with heavier forces. While neither the RedBlue nor the Sea Salt Lemon switches fall into this category, they can still provide a satisfactory typing experience due to their medium-light actuation and bottom out forces.
Travel distance
The travel distance of a switch is an important factor to consider when choosing a keyboard. In the case of the SP-Star RedBlue linear switch and the KTT Sea Salt Lemon linear switch, both switches have a travel distance of 4 mm. This means that pressing down on a key equipped with either switch will provide a similar tactile experience. Whether you opt for the SP-Star RedBlue or the KTT Sea Salt Lemon, you can expect the same level of feedback and key response. It is worth noting that the travel distance of 4 mm falls within the average range for keyboard switches, providing a comfortable and familiar typing experience for users.

Typing experience
In terms of sound, the RedBlue linear switch is best described as having a low-pitched sound profile. Low-pitched switches typically have a more bass-heavy and mellow tone compared to higher-pitched switches. Additionally, the RedBlue switch is also described as neutral in terms of sound, meaning it has a moderate sound profile that is suitable for most users. However, it is important to note that the sound produced by a switch is also influenced by other factors such as the keyboard board and keycaps used.
Similarly, the Sea Salt Lemon linear switch is also described as having a low-pitched sound profile. This means that it too produces a more bass-heavy and mellow tone. Like the RedBlue switch, the Sea Salt Lemon is also described as neutral in terms of sound, making it suitable for a wide range of users and purposes. Again, it is important to consider other factors that can influence the sound of the switch.
In terms of feel, the RedBlue linear switch offers a mild typing experience. This means that it provides a more gentle and approachable feel compared to switches with more pronounced characteristics. The RedBlue switch is also described as polished, which indicates that it has a smooth and refined finish. This results in a sleek typing experience with reduced friction and smooth key travel. On the other hand, the Sea Salt Lemon linear switch is also described as providing a mild typing experience. While no information is provided regarding its finish or smoothness, we can expect it to offer a similar gentle feel as the RedBlue switch.
In conclusion, the RedBlue linear switch is best suited for those who prefer a medium-light typing experience and a relatively higher-pitched sound profile. It offers a mild and polished feel, providing a gentle and smooth typing experience. The Sea Salt Lemon linear switch, while lacking information on its typing experience and finish, can be expected to provide a similar mild feel and low-pitched sound profile. Ultimately, the choice between these switches will come down to personal preference and the specific requirements of the user.
Conclusion
In closing, if you prefer a medium-light typing experience and enjoy a relatively higher-pitched sound profile, the SP-Star RedBlue linear switch would be a great choice for you. These switches offer a low-pitched, neutral, and thocky sound profile. Additionally, they provide a mild and polished feel, giving you a gentle and smooth typing experience.
On the other hand, if you are looking for a buttery smooth typing experience with a medium-light bottom out force, the KTT Sea Salt Lemon linear switch is the way to go. These switches offer a low-pitched and neutral sound profile. With their progressive spring and KTT's dry-lube design, they provide a mild and comfortable typing experience.
Ultimately, the decision between the SP-Star RedBlue and KTT Sea Salt Lemon switches depends on your preferences for typing experience and sound profile. Consider whether you prioritize a higher-pitched sound with a polished feel or a buttery smooth typing experience with a mild feel. Choose the switch that aligns best with your preferences to enhance your typing enjoyment.
