TTC Iron vs. SP-Star Polaris Purple
An in-depth look at the TTC Iron and the SP-Star Polaris Purple switches—which one is the best fit for you?
Overview
When considering mechanical keyboard switches, two popular options to compare are the TTC Iron linear switch and the SP-Star Polaris Purple tactile switch. The TTC Iron is celebrated for its pronounced clacky sound signature and lightweight actuation, making it an ideal choice for individuals looking for a satisfying typing experience without straining their fingers. On the other hand, the Polaris Purple offers a significant tactile bump that enhances the typing experience with a snappy sound profile. While the Iron is known for its ease of use and clacky sound, the Polaris Purple provides a more tactile and polished feel. 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 TTC Iron and SP-Star Polaris Purple switches both offer unique sound profiles, with POM creating a deeper and more muted sound in the Iron switches, and polycarbonate producing a sharper, higher-pitched sound in the Polaris Purple switches. The use of polycarbonate in the top housing of the Polaris Purple switches is especially advantageous for those looking to incorporate RGB lighting, as the material's translucency allows for vibrant lighting effects. In contrast, the POM material used in the Iron switches may be more suited for those looking for a quieter and more subdued typing experience.
In terms of the bottom housing, both the Iron's POM and the Polaris Purple's polycarbonate materials contribute to the overall sound profile of the switches. The stiffer nature of polycarbonate lends itself to a clearer and more resonant sound, whereas the POM material provides a deeper and more muted sound in the Iron switches. While both materials offer their own unique characteristics, the choice between them ultimately depends on the user's preference for sound profile and typing experience. Additionally, the impact of the bottom housing on the bottom-out sound and feel of the switches should also be taken into consideration when choosing between the two.
Overall, the decision between the housing materials of the TTC Iron and SP-Star Polaris Purple switches comes down to personal preference and desired typing experience. While the Iron switches offer a more muted sound profile with POM housings, the Polaris Purple switches provide a crisper and higher-pitched sound with polycarbonate housings. Whether one prefers the deeper sound of POM or the sharper sound of polycarbonate, both materials offer their own unique benefits and contribute to an overall satisfying typing experience. Ultimately, users should consider factors such as sound profile, tactile feedback, and aesthetics when choosing between these two housing materials.
Weight
The TTC Iron linear switch has a lighter actuation force of 41 grams compared to the SP-Star Polaris Purple tactile switch, which has an unknown actuation force. However, the Iron has a heavier bottom out force of 50 grams, while the Polaris Purple has a bottom out force of 67 grams. This means that the Polaris Purple requires a stronger push for a more substantial typing experience. For those who prefer a lighter typing experience that allows them to type for longer periods of time, the Iron may be the better choice. On the other hand, those who enjoy a more tactile and heavy typing feel may opt for the Polaris Purple. Ultimately, the choice between the two switches will depend on personal preference and typing style.
Travel distance
The TTC Iron linear switch has a travel distance of 3.8 mm, while the SP-Star Polaris Purple tactile switch has a travel distance of 4 mm. This means that the Polaris Purple has a slightly longer travel distance compared to the Iron switch. Generally, a shorter travel distance is preferred for faster response times, which could make the Iron switch more appealing to gamers. On the other hand, a longer travel distance may provide a more satisfying and deliberate feel when typing, making the Polaris Purple a better choice for those who prefer a deeper keypress. However, both switches fall within a similar range of travel distance, so the difference in feel may not be significant and both could provide similar results in terms of typing experience.
