Outemu Lime vs. KTT Purple Star

An in-depth look at the Outemu Lime and the KTT Purple Star switches—which one is the best fit for you?

Overview

When considering mechanical keyboard switches, two popular options to look at are the Outemu Lime, a tactile switch, and the KTT Purple Star, a linear switch. The Lime switches stand out for their lightweight design, approachable tactility, and silent operation, making them perfect for tactile enthusiasts who prefer a feathery light typing experience with just a hint of tactility. On the other hand, the Purple Star switches are renowned for their smooth all-POM construction, providing a buttery typing feel with a neutral sound profile. With a very light 45g bottom-out force, the Purple Star switches are ideal for those who prefer a gentle and comfortable typing experience. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials

In comparing the housing materials of the Outemu Lime and the KTT Purple Star switches, it is evident that both switches utilize different materials for their top and bottom housings. The Lime switch features a nylon top housing, which is known for absorbing sound and creating a duller, rounder sound profile. On the other hand, the Purple Star switch utilizes a POM top housing, which is said to produce a unique and pleasing sound that is deeper and more muted. Despite the differences in material, both top housings are geared towards enhancing the overall sound profile of the switch.

Moving on to the bottom housing materials of the two switches, the Lime switch once again utilizes a nylon bottom housing, which contributes to a deeper and fuller sound profile when typing. Similarly, the Purple Star switch features a POM bottom housing, which is known for creating a unique sound that is on the deeper side and relatively more muted. While the specific qualities of each bottom housing material may vary slightly, both are designed to enhance the tactile and auditory feedback of the switch during use.

When considering how the top and bottom housing materials of a switch interact, it is important to note that they both play a role in shaping the overall typing experience. The bottom housing material has a greater impact on the bottom-out sound and feel of the switch, while the top housing material influences the sound when a key is released. Despite the differences in materials between the Outemu Lime and KTT Purple Star switches, both are designed to optimize the typing experience through a combination of sound absorption, tactile feedback, and overall sound profile.

Weight

When comparing the actuation force and bottom out force of the Outemu Lime tactile switch and the KTT Purple Star linear switch, it is evident that the Lime is lighter in terms of both actuation and bottom out forces. The Lime requires 35 grams to actuate and 45 grams to bottom out, while the Purple Star necessitates 43 grams to actuate and 50 grams to bottom out. Both switches provide a relatively light typing experience, making them suitable for extended typing sessions. However, for those who prefer a more substantial typing feel, the Purple Star may be a better choice due to its slightly heavier forces. Ultimately, the decision between the two switches will depend on individual preferences for typing feedback and the desired weight of keypresses.

Travel distance

The Outemu Lime tactile switch has a travel distance of 3.3 mm, while the KTT Purple Star linear switch has a travel distance of 3.5 mm. In this case, the KTT Purple Star has a slightly longer travel distance compared to the Outemu Lime. Both switches fall within the range of shorter travel distances, as the traditional range is between 3.0 mm to 4.0 mm. Gamers may prefer the Outemu Lime for its slightly shorter travel distance, allowing for faster response times during gameplay. On the other hand, those who prefer a more substantial keypress may opt for the KTT Purple Star with its slightly longer travel distance. Ultimately, the choice between these two switches depends on personal preference for key travel depth.
