Housing materials
The HMX Blue Topaz and the Outemu Dustproof Purple both feature polycarbonate top housings, which result in a sharper, higher-pitched, and crisper sound profile. This is due to the stiffness of polycarbonate, creating a more clear and resonant sound. Additionally, the translucency of polycarbonate makes it ideal for switches with RGB lighting, adding an aesthetic appeal to the overall design. While both switches share this feature, the differences lie in their bottom housings.
The Blue Topaz utilizes a nylon bottom housing, which contributes to a deeper and fuller sound profile when typing. This is because nylon is a softer plastic that absorbs more sound, resulting in a duller and rounder sound. On the other hand, the Dustproof Purple also features a nylon bottom housing, providing similar qualities in terms of sound profile. The use of nylon in the bottom housing of these switches showcases how different materials can impact the overall typing experience.
When comparing the two switches, it is important to note that the qualities of each housing material are divided between the top and bottom of the switch. The bottom housing affects the bottom-out sound and feel when pressing down on the switch, while the top housing has more of an impact on the sound when releasing a key. This division highlights how the combination of housing materials in a switch can create a unique typing experience, with each material playing a specific role in the overall sound profile.
Weight
The HMX Blue Topaz linear switch has a lighter actuation force of 40 grams compared to the Outemu Dustproof Purple clicky switch's actuation force of 55 grams, making the Blue Topaz easier to press. However, when it comes to bottom out force, the Blue Topaz requires 48 grams while the Dustproof Purple requires 65 grams, indicating that the Dustproof Purple is heavier to press all the way down. This means that the Blue Topaz is a better option for those who prefer a lighter touch and may type for longer periods, while the Dustproof Purple is more suitable for individuals who prefer a stronger push feel for a more substantial typing experience. In terms of weight, the Blue Topaz is lighter overall, offering a softer typing experience, while the Dustproof Purple is medium-heavy, providing a more tactile and firm typing feedback. Ultimately, the choice between the two switches depends on individual preferences for typing feel and force requirements.
Travel distance
The HMX Blue Topaz linear switch has a travel distance of 3.9 mm, while the Outemu Dustproof Purple clicky switch has a travel distance of 4 mm. Both switches fall within the range of shorter travel distances, making them ideal for gamers looking for quick response times. The difference of 0.1 mm between the two may not be significant to most users, but those who prefer a slightly deeper press may opt for the Dustproof Purple switch. On the other hand, the Blue Topaz switch offers a slightly shorter travel distance, which may appeal to those who prefer a more responsive feel. Ultimately, both switches provide a similar experience in terms of travel distance, so users can expect comparable results from either option.
