HMX 1989 vs. TTC Iron
An in-depth look at the HMX 1989 and the TTC Iron switches—which one is the best fit for you?
Overview
When it comes to mechanical keyboard switches, the HMX 1989 and TTC Iron stand out in the realm of linear options, each offering unique characteristics that cater to different typing preferences. The HMX 1989, well-regarded for its deep and “thocky” sound profile, delivers a satisfying auditory experience that many gamers and typists covet, especially during intense sessions. On the other hand, the TTC Iron provides a pronounced clacky sound signature that enhances the feedback while typing, allowing users to revel in the aural satisfaction that accompanies each press. In terms of feel, the TTC Iron boasts remarkably light actuation, leading to swift and fatigue-free typing, which is essential for prolonged use. While both switches offer smooth travel and an enjoyable experience, the choice between them may come down to personal preference—do you prefer the deep thock of the HMX 1989 or the exciting clack of the TTC Iron? However, let's dive in a bit deeper beyond generalities so you can best decide on the switch that perfectly suits your typing style.

Housing materials
When comparing the housing materials of the HMX 1989 and the TTC Iron, distinct differences emerge that influence their sound profiles. The HMX 1989 utilizes a polycarbonate top housing, which contributes to a sharper, higher-pitched, and crisper sound. Polycarbonate's rigidity fosters clarity and resonance, making it an ideal choice for enhancing sound when RGB lighting is employed due to its translucency. In contrast, the TTC Iron features a POM top housing, which produces a deeper and more muted sound profile. This fundamental difference in material results in contrasting auditory experiences: the 1989 likely delivers a more vibrant sound under various lighting conditions, whereas the Iron offers a more subdued acoustic signature, appealing to those who prefer a less piercing auditory experience.
Looking at the bottom housing materials, both the HMX 1989 and the TTC Iron showcase a blend of functionality and sound characteristics. The 1989 employs a nylon bottom housing, revered for its classic status in switch design, promoting a deeper and fuller sound due to nylon's softer nature. This material's capacity to absorb sound gives it a unique quality that works well for those who appreciate a rounded auditory profile. On the other hand, the Iron also opts for POM in its bottom housing, which shares similarities in sound character by producing a pleasing and unique sound with a deeper resonance. Although POM is harder than nylon, the overall sound produced remains muted and is complementary to various keyboard designs.
Ultimately, the impact of these materials on the overall switch experience can be nuanced. While the HMX 1989's polycarbonate top and nylon bottom leverage different sound profiles—crisper highs from the top and rounder lows from the bottom—the TTC Iron brings a unity of deeper tones by utilizing POM for both housings. If we consider what users might expect in terms of sound from both switches, there is a cohesive blend of deeper tones from the Iron that appeals to those favoring a muted sound profile, while the 1989 provides a more diverse auditory experience combined with RGB lighting capabilities. Thus, owning both switches can yield different auditory sensations, but they share the ability to produce satisfying sound profiles tailored to different preferences.
Weight
When comparing the HMX 1989 linear switch to the TTC Iron linear switch, there are notable differences in both actuation and bottom out forces. The HMX 1989 has an actuation force of 45 grams and a bottom out force of 53 grams, making it a medium-light switch. In contrast, the TTC Iron features a lighter actuation force of 41 grams and a bottom out force of 50 grams. This means that the TTC Iron is easier to press down, making it a preferable option for those who type for extended periods or wish to experience less finger fatigue during long gaming sessions. On the other hand, the HMX 1989's slightly heavier actuation and bottom out forces provide a more substantial typing experience, appealing to users who favor a stronger tactile feedback. Thus, while both switches provide a linear response, the TTC Iron is the lighter option and the HMX 1989 is the heavier alternative.
Travel distance
The HMX 1989 linear switch features a travel distance of 4 mm, making it the longer option compared to the TTC Iron linear switch, which has a travel distance of 3.8 mm. This 0.2 mm difference may seem minimal, but it can significantly impact the typing experience. The HMX 1989, with its extended travel, offers a more pronounced tactile feedback, which some users may prefer for a satisfying keystroke. On the other hand, the TTC Iron's shorter travel distance caters to those seeking quicker response times, often favored by gamers who thrive on speed and efficiency. Ultimately, if you prioritize a deeper, more substantial keypress, the 1989 is the better choice, while the Iron is ideal for those who favor a speedier, more responsive feel.

In contrast, the TTC Iron linear switch stands out with its clacky sound signature, which is characterized by a sharp, snappy, and percussive sound that enhances the enjoyment of each keystroke. Although both switches deliver distinct sound profiles, they cater to different auditory preferences. The sound quality is also influenced by factors like the keyboard construction and keycap choice, meaning that users can customize their experience further based on these elements.
Regarding feel, the HMX 1989 switch is recognized for its smoothness and responsiveness, although specific details about its tactile characteristics were not provided. In comparison, the TTC Iron linear switch shines with its easy-to-press feel, requiring minimal force for activation. This makes it exceptionally comfortable for long typing sessions, as it reduces finger fatigue. The Iron's mild actuation and gentle resistance create a pleasant typing experience, appealing to a wide range of users from beginners to enthusiasts.
Overall, while the HMX 1989 linear switch appeals to those looking for a deeper acoustic experience, the TTC Iron linear switch offers a lighter, clackier sound that many may find more engaging.

Conclusion
To conclude, choosing between the HMX 1989 linear switch and the TTC Iron linear switch comes down to your personal preferences and typing needs. If you are looking for a switch that delivers a deeper, thocky sound and provides a slightly higher actuation force of 53 grams, the HMX 1989 is an excellent choice, especially if you enjoy a more substantial typing experience that balances tactile feedback with a satisfying auditory profile. This makes it well-suited for gaming where precise actuation feels rewarding. Conversely, if you prioritize a light touch and swift, fatigue-free typing with a pronounced, clacky sound signature, the TTC Iron may be the better option for you. Its 50 grams of actuation force allows for effortless keystrokes, making it ideal for long typing sessions or those who prefer a more responsive feel. Furthermore, the Iron's mild characteristics make it versatile, appealing to both newcomers and seasoned typists alike. Ultimately, your decision should reflect the type of sound and feel that you find most enjoyable for your specific use case.
