Housing materials
Both the HMX Blue Topaz and TTC Iron switches have unique housing materials that contribute to their sound profiles. The Blue Topaz features a polycarbonate top housing, which is known for creating a sharper and crisper sound. In contrast, the Iron utilizes a POM top housing that produces a deeper and more muted sound. While the materials differ in terms of sound profile, both switches offer a distinct auditory experience that can cater to different preferences.
In terms of bottom housing, the Blue Topaz utilizes a nylon material that creates a deeper and fuller sound profile. The softer nature of nylon absorbs more sound, resulting in a duller and rounder sound compared to the stiffer polycarbonate utilized in the top housing. Conversely, the Iron also features a POM bottom housing, which contributes to the switch's unique sound profile that is on the deeper side and relatively more muted. Despite the differences in material, both bottom housings offer qualities that enhance the overall typing experience.
When comparing the top and bottom housing materials of the HMX Blue Topaz and TTC Iron switches, it is evident that each material brings its own set of characteristics to the table. While the top housing influences the sound when a key is released, the bottom housing has more of an impact on the bottom-out sound and feel when pressing down on a key. Ultimately, whether you prefer the sharper sound of polycarbonate or the deeper sound of POM, both switches offer a high-quality typing experience that showcases the importance of housing materials in switch design.
Weight
The actuation force and bottom out force of the HMX Blue Topaz linear switch and the TTC Iron linear switch are quite similar. The Blue Topaz has an actuation force of 40 grams and a bottom out force of 48 grams, while the Iron has an actuation force of 41 grams and a bottom out force of 50 grams. Both switches have relatively light actuation and bottom out forces, making them suitable for those who prefer a lighter typing experience. However, the slight difference in weight between the two switches may be noticeable to some users. Some may find the Blue Topaz to be slightly lighter, making it ideal for longer typing sessions, while others may prefer the slightly heavier feel of the Iron for a more substantial typing experience. Ultimately, the choice between the two switches will depend on individual preference for actuation and bottom out forces.
Travel distance
The travel distance of the HMX Blue Topaz linear switch is 3.9 mm, while the TTC Iron linear switch has a travel distance of 3.8 mm. Both switches fall within the realm of shorter travel distances, making them ideal for individuals seeking faster response times, such as gamers. The slight difference in travel distance may not be noticeable to most users, as they will both provide a similar experience in terms of keypress depth. However, for those who may be more sensitive to small variations in travel distance, the Blue Topaz would be considered the longer option, while the Iron would be slightly shorter. Ultimately, both switches offer a shorter travel distance compared to traditional options, catering to users who prioritize speed and responsiveness in their typing experience.
