Kailh Plum vs. SP-Star Polaris Gray
An in-depth look at the Kailh Plum and the SP-Star Polaris Gray switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, there are countless options to choose from, each with its own unique characteristics. Two switches that deserve attention are the Kailh Plum, a tactile switch, and the SP-Star Polaris Gray, a linear switch. The Plum stands out for its hefty feel and unique lack of a pronounced tactile bump, setting it apart from many other tactile switches. Its sound profile is neutral and pleasant, making it a great choice for those seeking a versatile typing experience. On the other hand, the Polaris Gray is perfect for those who prefer a bouncy typing feel. These switches offer a clean and clacky sound profile, adding a satisfying auditory element to your typing. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The Kailh Plum and the SP-Star Polaris Gray both feature polycarbonate top housings. This material creates a sharper, higher-pitched, and crisper sound profile, making it ideal for those seeking a more distinct typing experience. Additionally, the translucency of polycarbonate allows for RGB lighting to shine through, adding an aesthetic appeal to the switch. Therefore, if you are looking for similar results in terms of sound and lighting options, both switches offer a polycarbonate top housing.
However, when it comes to the bottom housing, there is a difference between the two switches. The Plum utilizes a nylon bottom housing, which produces a deeper and fuller sound profile. The softer nature of nylon absorbs more sound, resulting in a duller and rounder sound. On the other hand, the Polaris Gray employs a polycarbonate bottom housing. While it still contributes to a clear and resonant sound profile, it may not provide the same deepness and fullness as nylon. This distinction in the bottom housing material can impact the overall sound and feel when typing on the switch.
When pressing down on either the Plum or the Polaris Gray switch, the qualities of the bottom housing material will be noticeable. The bottom housing has a significant influence on the bottom-out sound and feel, contributing to the overall tactile feedback. Conversely, the top housing material will affect the sound when you release a key, adding to the overall typing experience. Therefore, understanding the differentiation in housing materials for each switch can help discern the specific characteristics and preferences one may have when selecting a keyboard switch.
Weight
When comparing the actuation force and bottom out force between the Kailh Plum tactile switch and the SP-Star Polaris Gray linear switch, there are some similarities and differences to consider. The actuation force of both switches is currently unspecified, making it difficult to directly compare them in this aspect. However, in terms of bottom out force, the Plum switch requires 70 grams of force, which is considered medium-heavy, while the Polaris Gray switch requires 67 grams, also falling within the medium-heavy range.
Both switches provide a relatively substantial typing experience due to their medium-heavy bottom out forces. If a heavier typing feel is preferred, the Plum switch would be the better option with its slightly higher bottom out force. On the other hand, if a slightly lighter typing experience is desired, the Polaris Gray switch would be the preferable choice.
Weight is an important consideration when choosing a keyboard switch, as it affects the typing experience and endurance during prolonged usage. For individuals who prefer a lighter feel, allowing them to type for extended periods, either switch would provide similar results, as the actuation force is not specified for either.
Ultimately, the choice between the Kailh Plum tactile switch and the SP-Star Polaris Gray linear switch depends on individual preferences. Those seeking a heavier keystroke may lean towards the Plum switch, while those looking for a slightly lighter touch may opt for the Polaris Gray switch. Ultimately, it is a matter of personal preference and the desired typing experience.
Travel distance
The Kailh Plum tactile switch and the SP-Star Polaris Gray linear switch have contrasting travel distances. The Plum has a travel distance of 3.6 mm, which is shorter than the traditional 4.0 mm travel distance. On the other hand, the Polaris Gray has a travel distance of 4 mm, which aligns with the traditional length. For those who prioritize faster response times and a more responsive typing experience, the Plum switch with the shorter travel distance would be the ideal choice. Gamers, in particular, often prefer shorter travel distances. However, for individuals who enjoy a more hearty and substantial feel when typing, the Polaris Gray switch with its longer travel distance would be more suitable. It ultimately comes down to personal preference and the desired typing experience.

Typing experience
The Kailh Plum tactile switch is known for its unique combination of weightiness and a lack of a large tactile bump. This gives it a hefty feel without sacrificing tactility. In terms of sound, the Plum is described as having a neutral sound profile that is enjoyable. On the other hand, the SP-Star Polaris Gray linear switch offers a bouncy typing experience. Its sound profile is clean and clacky, with a low-pitched tone that is more bass-heavy and mellow compared to higher-pitched switches. Both switches have a moderate actuation force requirement, making them suitable for various purposes and skill levels. The Plum switch has a mild feel, offering a gentle typing experience with a middle-ground sensation between pre-travel and post-travel. The Polaris Gray switch also has a mild feel but is described as polished, resulting in a smoother and more refined typing experience with reduced friction. Overall, while the Plum tactile switch and the SP-Star Polaris Gray linear switch have different qualities in terms of sound and feel, they both provide enjoyable experiences and are suitable for most users.
Conclusion
To sum up, if you are someone who values a unique tactile experience without a significant tactile bump, and prefers a medium-heavy bottom out force, the Kailh Plum tactile switch would be a great choice for you. These switches offer a neutral sound profile that is enjoyable to use in various settings, whether at home or at work. On the other hand, if you prefer a bouncy typing experience and a slightly lower bottom out force, the SP-Star Polaris Gray linear switch would be a better fit. These switches have a clean and clacky sound profile with a low-pitched tone, providing a different auditory experience. Both switches offer a mild typing feel, making them approachable and suitable for most users. However, if you prefer a polished switch with reduced friction and smooth key travel, the Polaris Gray would be the better option. Ultimately, the choice between the Kailh Plum tactile switch and the SP-Star Polaris Gray linear switch depends on your preferred tactile feel, sound profile, and overall typing experience.
