HMX Swift vs. SP-Star Yanyu
An in-depth look at the HMX Swift and the SP-Star Yanyu switches—which one is the best fit for you?
Overview
When comparing the HMX Swift and the SP-Star Yanyu mechanical keyboard switches, both linear switches offer distinct characteristics that cater to different preferences. The Swift is noted for its deeper sound profile, attributed to its full nylon housings, and a silky smooth feel with a delicate 42g actuation force. On the other hand, the Yanyu is praised for its crisp sound profile and suitability for prolonged typing sessions, thanks to its material blend. While the Swift is described as 'Clacky', 'Easy-to-press', 'Feathery', 'Bouncy', and 'Creamy', the Yanyu is categorized as 'Neutral', 'Mild', 'Thocky', 'Feathery', 'Subtle', and 'Polished'. These general characteristics can guide your decision, however, let's dive in a bit deeper beyond generalities so you can best decide on the best switch for you.

Housing materials
The housing materials of the HMX Swift and the SP-Star Yanyu both utilize nylon in their constructions, which results in a deeper and fuller sound profile when typing on the switches. However, the Yanyu takes it a step further by incorporating a blend of Polymer nylon and UHMWPE in both the top and bottom housings, offering a unique sound profile that is described as pleasant and slightly brighter. This blend of materials sets the Yanyu apart from the Swift in terms of sound characteristics.
While the Swift and Yanyu both feature nylon top housings, the Yanyu stands out with its Polymer nylon and UHMWPE blend which contributes to a slightly brighter sound profile compared to the deeper sound produced by the Swift's nylon top housing. Additionally, the Yanyu's unique blend creates a sound that is described as pleasant, catering to those who prefer a softer and more subtle typing experience. This difference in sound profile highlights the impact that housing material composition can have on the overall performance of a mechanical switch.
The split between the bottom and top housings in a switch allows for the unique qualities of each material to be felt differently during typing. The bottom housing, which has more of an impact on the bottom-out sound and feel, will showcase the characteristics of the specific material used, such as nylon in the case of the Swift or the blend of Polymer nylon and UHMWPE in the Yanyu. Conversely, the top housing will influence the sound produced when releasing a key, providing a balanced and nuanced typing experience based on the composition of the housing materials in each switch.
Weight
The actuation force and bottom out force of the HMX Swift linear switch and the SP-Star Yanyu linear switch have some key differences. The Swift has a light actuation force of 42 grams and a bottom out force of 50 grams, while the Yanyu's actuation force is unknown and has a bottom out force of 43 grams. Both switches are on the lighter side, which is ideal for those looking for a more comfortable typing experience for extended periods of time. However, for those who prefer a more substantial typing experience with a stronger push feel, they may want to consider options with heavier forces. In this case, the Swift would be the lighter option, while the Yanyu would be slightly heavier due to its slightly higher bottom out force. Ultimately, the choice between the two switches would depend on personal preference for typing feel and keypress weight.
Travel distance
The HMX Swift linear switch has a travel distance of 3.9 mm, while the SP-Star Yanyu linear switch has a travel distance of 4 mm. Both of these switches fall within the range of shorter travel distances, which are becoming increasingly popular, especially among gamers seeking faster response times. The slight difference in travel distance between the two switches may not be noticeable to most users, but those who prefer a slightly deeper feel may opt for the Yanyu switch with its slightly longer travel distance. Ultimately, the choice between the two switches will depend on individual preference for either a slightly shorter or slightly longer travel distance.

Typing experience
In terms of sound, the HMX Swift linear switch offers a unique clacky sound profile, providing a sharp, snappy, and percussive sound when pressed. This sound is complemented by the deeper sound profile produced by the full nylon housing, creating a silky smooth typing experience. On the other hand, the SP-Star Yanyu linear switch is known for its neutral sound profile, with a blend of materials that give it a crisp and satisfying thocky sound. The Yanyu switch is versatile and suitable for various typing environments. Ultimately, the choice of sound between the Swift and Yanyu switches will depend on personal preference and the setup of the keyboard and keycaps.
When it comes to feel, the HMX Swift switch offers an easy-to-press and feathery typing experience, with minimal resistance and a light actuation force of 42g. Typing on the Swift switch feels effortless and comfortable, reducing finger fatigue during extended typing sessions. In contrast, the SP-Star Yanyu switch provides a mild and subtle typing feel, with a gentle resistance that is approachable to most users. The Yanyu switch also features a feathery sensation, reducing finger strain and promoting comfortable typing for extended periods. Both switches offer smooth and polished typing experiences, enhancing the overall typing feel.
Considering the subjective qualities of sound and feel, the HMX Swift and SP-Star Yanyu linear switches offer distinct typing experiences to users. The Swift switch excels in providing a deeper and clacky sound profile, paired with an easy-to-press and feathery typing feel.
