Housing materials

The housing materials of the Durock Piano and the SP-Star Polaris Purple differ in terms of their composition and resulting sound profiles. The Piano utilizes a proprietary POM blend for both the top and bottom housing, offering a satisfying and deep sound profile. While the exact details of this blend remain unknown, its impact is evident in the overall sound experience. In contrast, the Polaris Purple incorporates polycarbonate in both its top and bottom housing. This choice of material creates a sharper, higher-pitched, and crisper sound profile. The stiffness of polycarbonate contributes to a clearer and more resonant sound. Additionally, the use of polycarbonate in the top housing allows for the inclusion of RGB lighting due to its translucency. Overall, the housing materials of these two switches result in distinct sound characteristics, with the Piano favoring a deep and satisfying tone, and the Polaris Purple emphasizing clarity and higher frequencies.

Despite their differences, the housing materials also share some similarities in terms of sound production. Both the POM blend used in the Piano's housing and the polycarbonate utilized in the Polaris Purple's housing contribute to the overall sound profile of the switches. While the POM blend offers a uniquely satisfying and deep sound profile in the Piano, the polycarbonate provides a clearer and crisper sound in the Polaris Purple. Both materials have their respective strengths and impact the sound experience in different ways. Additionally, the use of polycarbonate in clear housings is a common practice, making it likely that both the top and bottom housing materials of these switches enhance their sound profiles in similar manners. Therefore, although each switch has its own distinct characteristics, both the Durock Piano and the SP-Star Polaris Purple can deliver comparable results in terms of sound by utilizing their respective housing materials effectively.

The impact of the top and bottom housing materials in these switches is important to consider, as it affects the overall sound production and tactile experience. In the case of the Durock Piano, the bottom housing made from the POM blend plays a significant role in determining the bottom-out sound and feel when a key is pressed. This housing material contributes to the satisfying and deep sound profile that the Piano is known for. On the other hand, the top housing material, which remains undisclosed but offers a uniquely satisfying and deep sound profile, influences the sound when a key is released. In the SP-Star Polaris Purple, the polycarbonate utilized in both the top and bottom housing materials allows for a sharper and crisper sound when pressing down on a key, emphasizing the impact of the bottom housing. Conversely, the top housing material, also polycarbonate, contributes to the sound when releasing a key. This distinction highlights how the choice of housing material can impact different aspects of the sound experience, making it crucial to consider the specific characteristics of each switch's top and bottom housing materials.

Weight

When comparing the actuation force and bottom out force of the Durock Piano linear switch and the SP-Star Polaris Purple tactile switch, we can see some similarities and differences. Both switches have an unknown actuation force, which means that the force required to trigger a keystroke is not specified for either switch. However, when it comes to the bottom out force, the Durock Piano has a slightly lighter bottom out force of 63.5 grams, while the SP-Star Polaris Purple has a slightly heavier bottom out force of 67 grams.

The weight of a switch is an important factor to consider, as it can greatly impact the typing experience. Those who prefer a lighter switch may opt for the Durock Piano, as it allows for longer typing periods without fatigue. This would be ideal for individuals using a keyboard for work or engaging in long gaming sessions. On the other hand, those who enjoy a more substantial typing experience may prefer the SP-Star Polaris Purple, with its slightly heavier bottom out force. This provides a stronger push feel and can enhance the overall typing sensation.

While the exact actuation force remains unknown for both switches, it is fair to assume that they may deliver similar results in terms of triggering a keystroke. However, it is important to note that the Durock Piano has a lighter bottom out force compared to the SP-Star Polaris Purple, making it the lighter option. Whether one prefers a lighter or heavier switch depends on personal preference and the desired typing experience.

Travel distance

Both the Durock Piano linear switch and the SP-Star Polaris Purple tactile switch have a travel distance of 4 mm. This means that when you press down on a key, you will feel the switch travel this distance from the top to the bottom. Both switches offer a similar typing experience in terms of travel distance, providing consistent feedback and responsiveness. Whether you choose the Durock Piano or the SP-Star Polaris Purple, you can expect a satisfying tactile sensation with a travel distance of 4 mm. Therefore, there is no significant difference in the travel distance of these two switches, ensuring similar results in terms of keypress feel.
