Keygeek Keylin vs. Bsun Tomcat (Heavy)

An in-depth look at the Keygeek Keylin and the Bsun Tomcat (Heavy) switches—which one is the best fit for you?

Overview

When choosing the perfect mechanical keyboard switch, the Keygeek Keylin and the Bsun Tomcat (Heavy) both offer compelling options for enthusiasts who prefer linear switches. The Keylin is celebrated for its innovative molds, providing a premium typing experience characterized by rich acoustics and exceptional smoothness, making it an excellent choice for those who value clear auditory feedback alongside a fluid keypress. On the other hand, the Bsun Tomcat (Heavy) features Ly stems, which contribute to a remarkably smooth typing experience as well, along with a resonant sound profile, appealing to users who enjoy a deeper, more resonant feedback while they type. Both switches cater to linear switch lovers, but they each bring unique qualities to the table. However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that fits your typing style and preferences.

Housing materials

When comparing the housing materials of the Keygeek Keylin and the Bsun Tomcat (Heavy), it's evident that there is a distinct difference in their top housing materials, which significantly influences the overall sound profile of each switch. The Keylin features a nylon top housing, recognized for producing a deeper and fuller auditory experience. This is due to nylon's softer composition, which absorbs sound more effectively than harder plastics. In contrast, the Tomcat (Heavy) is constructed with a polycarbonate top housing, which delivers a sharper, higher-pitched sound profile thanks to its stiffer material. This variation means that while both switches may feel responsive, the auditory feedback will differ quite distinctly when pressing and releasing the keys due to the inherent sound qualities of nylon versus polycarbonate.

However, both switches share the same bottom housing material, nylon, which is notable for its characteristics. As both the Keylin and the Tomcat (Heavy) utilize nylon for their bottom housings, they elicit a similar sound profile underlining a deeper and more resonant experience when bottoming out. Nylon's absorption properties ensure that users of either switch will notably enjoy a gratifying tactile sensation with a duller, rounder sound when the key is pressed down. This shared material in the bottom housing helps bridge the auditory experience between the two models, despite their differences in the top sections, allowing a partially overlapping acoustic character.

Ultimately, while the Keylin and Tomcat (Heavy) present contrasting aesthetics and sound profiles in their top housings, their shared nylon bottom housing harmonizes their tactile experience. This means that even though you might notice a pronounced difference in auditory feedback when the keys are released, the full mechanical experience of each switch retains a similar foundation from the nylon bottom housing. Thus, users can expect a satisfying and rich bottom-out feel from both switches, allowing for a mixed but complementary typing experience that caters to different auditory preferences at the same time.

Weight

When comparing the Keygeek Keylin linear switch to the Bsun Tomcat (Heavy) linear switch, we find notable differences in both actuation and bottom out forces that influence their overall typing feel. The Keylin features a lighter actuation force of 38 grams and a bottom out force of 48 grams, making it ideal for those who prefer a light touch for extended typing sessions, such as during work or long gaming periods. In contrast, the Tomcat (Heavy) has a heavier actuation force of 55 grams and a bottom out force of 64 grams, providing a more substantial feel that some users find preferable for a tactile response. As a result, the Keylin is the lighter option, suitable for those seeking comfort and ease, while the Tomcat (Heavy) caters to individuals who appreciate a firmer push. Ultimately, the differences in actuation and bottom out forces emphasize the contrasting user experiences each switch offers.

Travel distance

Both the Keygeek Keylin linear switch and the Bsun Tomcat (Heavy) linear switch feature an identical travel distance of 3.6 mm. This means that when pressed, users will experience the same amount of travel from the top to the bottom of each switch, resulting in similar tactile feedback and responsiveness. Consequently, whether utilizing the Keylin or the Tomcat (Heavy), typists and gamers alike can expect a consistent performance in terms of key press depth, making either switch a comparable choice for those who prefer linear switches.

Typing experience

In terms of sound, the Keygeek Keylin linear switch is recognized for its rich acoustics, offering a pleasing auditory experience during typing. This richness contributes to a fuller sound profile that many users find satisfying and enhances the overall enjoyment of using the keyboard. Conversely, the Bsun Tomcat (Heavy) linear switch delivers a resonant sound profile, indicating a solid sound character that resonates distinctly. Both switches produce enjoyable auditory feedback, although the Keylin leans towards a deeper and more pronounced tone while the Tomcat brings out a more resonant quality.

When it comes to feel, the Keylin switch is lauded for its exceptional smoothness, providing a seamless typing experience that many enthusiasts crave. This smoothness is characteristic of well-manufactured switches that prioritize user comfort during extended typing sessions. On the other hand, the Tomcat (Heavy), featuring Ly stems, is designed specifically for a super smooth typing experience as well. Users of both switches can therefore expect a consistent and effortless actuation, making them ideal for both typing and gaming scenarios.

In conclusion, while the Keygeek Keylin and Bsun Tomcat (Heavy) linear switches each bring their unique qualities, they both promise smooth performance and satisfying auditory feedback. The Keylin stands out with its rich acoustics, while the Tomcat offers a resonant tone. For users looking for a premium typing experience characterized by smoothness, both switches deliver on that front, ensuring that newcomers will likely enjoy either option greatly. Ultimately, choosing between them may come down to personal preference regarding the sound profile, as they share similarities in their overall feel and performance.

Conclusion

To conclude, choosing between the Keygeek Keylin linear switch and the Bsun Tomcat (Heavy) linear switch ultimately comes down to your personal preferences and typing style. If you prefer a lighter touch and a smooth, agile feel for rapid typing or gaming, the Keylin’s bottom out force of 48 grams will be ideal for you. Its premium build, enhanced acoustics, and exceptional smoothness make it excellent for extended typing sessions without fatigue. On the other hand, if you lean towards a firmer, more substantial feel while typing—perhaps for a more deliberate, controlled approach—the Tomcat (Heavy), with its 64 grams of force, would serve you well. Featuring Ly stems that promote an equally smooth experience, the Tomcat adds a resonant sound profile that can enhance your overall tactile experience. In deciding between the two, consider how much tactile feedback you prefer, how you plan to use your keyboard, and whether you value auditory sensations or the lightness in your switches. Whatever you choose, both options promise to elevate your mechanical keyboard experience.
