HMX Lucky vs. KTT Purple Star
An in-depth look at the HMX Lucky and the KTT Purple Star switches—which one is the best fit for you?
Overview
When it comes to choosing the perfect mechanical keyboard switch, the HMX Lucky and KTT Purple Star stand out as two appealing linear options, each offering distinct advantages for different types of users. The HMX Lucky is renowned for its softer and glittery nylon housings, providing a lightweight feel that creates a neutral and deeply satisfying typing experience. This switch is ideal for those who appreciate a gentle touch and a more forgiving keypress. On the other hand, the KTT Purple Star features a robust all-POM construction, known for delivering a buttery smooth typing experience coupled with a neutral sound signature. With a very light 45g bottom-out force, the Purple Star is particularly suited for light typists seeking ease and comfort during prolonged sessions. Both switches cater to users who prioritize a smooth and consistent feel, yet they diverge in manufacturing materials and the type of tactile feedback they provide. However, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
When comparing the housing materials of the HMX Lucky and the KTT Purple Star, the notable differences lie in the types of plastics used for each switch. The HMX Lucky utilizes nylon for both its top and bottom housings, which is recognized for its unique acoustic properties. Nylon, being a softer plastic, provides a deeper and fuller sound profile while absorbing more sound than harder materials. This characteristic leads to a rounder, more muted auditory experience when the switches are engaged. In contrast, the KTT Purple Star features POM (Polyoxymethylene) for both its top and bottom housings. POM is known for delivering a pleasing and unique sound profile, which, while also deeper and more muted, differs in texture and resonance due to its distinctive material properties.
When considering the impact of these materials on typing experience and sound, both the HMX Lucky and KTT Purple Star produce a relatively deeper sound profile, yet they achieve this through different means. While the nylon top and bottom housings of the Lucky create a cohesive acoustic experience characterized by softness and warmth, the POM housing of the Purple Star adds a slight crispness that complements its muted sound. The modifiers introduced by each material mean that the specific auditory characteristics, although similar in depth and fullness, have a different textural quality. Thus, users may perceive the sound signature of each switch distinctly, influencing their overall typing experience.
In terms of sound behavior, since both the HMX Lucky and KTT Purple Star feature unique strengths in their respective housing materials, the overall acoustic profile will be affected by how each housing interacts. For instance, with the Lucky's nylon contributing to a rounder bottom-out sound while allowing for a softer release noise, the Purple Star's POM may create a tighter, yet still full sound on bottom-out but with a snappier release effect. Ultimately, while the materials are different, the resulting experiences with both switches will produce satisfying performances, underscoring that similar outcomes—deeper, more muted sounds—can be achieved through different compositions of housing materials, with each yielding its unique flavor to the typing experience.
Weight
When comparing the HMX Lucky linear switch and the KTT Purple Star linear switch, we observe notable differences in their actuation and bottom out forces. The HMX Lucky has a lighter actuation force of 37 grams and a bottom out force of 43 grams, making it an excellent choice for those who prefer a softer touch for extended typing or gaming sessions. In contrast, the KTT Purple Star requires a slightly heavier actuation force of 43 grams and a bottom out force of 50 grams, appealing to users who favor a more substantial feel when typing. Thus, while both switches are classified as light, the HMX Lucky is lighter overall, providing a more effortless actuation, whereas the KTT Purple Star offers a firmer resistance suitable for those seeking a stronger push. If both switches are used, the HMX Lucky would yield a lighter and gentler typing experience, whereas the KTT Purple Star would provide a weightier interaction.
Travel distance
When comparing the travel distances of the HMX Lucky linear switch and the KTT Purple Star linear switch, the Lucky offers a travel distance of 3.8 mm, whereas the Purple Star has a slightly shorter travel distance of 3.5 mm. Given that 4.0 mm is the most traditional distance, both switches fall within a range that can be considered relatively common among modern linear switches. However, the Lucky's longer travel distance may appeal to users who prefer a more substantial keypress, allowing for a deeper feel and potentially better tactile feedback. On the other hand, gamers seeking rapid response times might favor the KTT Purple Star due to its shorter travel distance, which allows for quicker actuation. Ultimately, the choice between the two switches will depend on personal preference, with the Lucky providing a more pronounced keystroke and the Purple Star enabling a snappier, less pronounced typing experience.

Typing experience
The HMX Lucky linear switch exhibits a sound profile that is not specifically documented, leaving its acoustic characteristics unclear. In contrast, the KTT Purple Star switch is defined by a low-pitched sound signature that provides a mellow, bass-heavy tone. This quality tends to create a more subdued auditory experience, which can enhance the overall typing atmosphere, especially when paired with the right board and keycaps. Ultimately, if you prioritize a quieter operation with a comforting sound, the Purple Star may be more aligned with your preferences.
When it comes to feel, the Lucky switch is noted for offering a neutral and deeply satisfying typing experience thanks to its softer nylon housings, but the specific tactile qualities remain unspecified. On the other hand, the Purple Star is recognized for its mild and easy-to-press nature, delivering a gentle typing experience that minimizes resistance during key presses. This usability makes it particularly comfortable for light typists and those who engage in prolonged typing sessions, as it reduces finger fatigue and enhances workflow efficiency. The combination of these qualities makes the Purple Star a strong contender for users seeking a smooth, enjoyable typing experience.
In summary, while both switches cater to unique typing needs, the HMX Lucky remains somewhat enigmatic in terms of sound and feel, whereas the KTT Purple Star offers a clearly defined and approachable auditory and tactile experience. If you find yourself drawn to a distinguished sound and a comfortable, low-impact feel, the Purple Star is likely the better option. However, if you're exploring switch options and aren't as particular about sound, the Lucky switch still presents a respectable choice for a neutral typing experience.
Conclusion
To conclude, the choice between the HMX Lucky and the KTT Purple Star linear switches ultimately depends on your personal preferences and typing habits. If you prefer a lighter actuation with a neutral and deeply satisfying typing experience, the Lucky switches might be your best bet, especially if you enjoy a more lightweight feel or seek to reduce finger fatigue during long usage. Their softer nylon housings may also appeal to those who appreciate a unique tactile experience and an engaging typing sensation. On the other hand, if you want a slightly firmer feel and value a buttery smooth, low-pitched sound signature, the KTT Purple Star switches would be more suitable for you. Their all-POM construction and mild typing characteristics make them appealing for those who appreciate a balance between comfort and responsiveness, with the added benefit of ease for light typists. Ultimately, your specific typing style, sound preferences, and feel will guide your decision in selecting the switch that best enhances your mechanical keyboard experience.
