Housing materials
In comparing the housing materials of the SP-Star Polaris Gray and the KTT Purple Star, it is evident that both switches utilize different materials for their top and bottom housings. The Polaris Gray features a polycarbonate top housing, known for creating a sharper, higher-pitched, and crisper sound profile, while the Purple Star incorporates a POM top housing that results in a deeper and relatively more muted sound. This contrast in sound profiles showcases how the choice of housing material can greatly impact the overall sound experience of a mechanical keyboard switch.
Moving on to the bottom housings, both the Polaris Gray and Purple Star switches also utilize different materials. The Polaris Gray employs a polycarbonate bottom housing, which contributes to its clear and resonant sound profile, whereas the Purple Star utilizes a POM bottom housing that enhances the deeper and more muted sound of the switch. This distinction highlights how the material of the bottom housing can influence the bottom-out sound and feel of a keypress, adding another layer of complexity to the overall typing experience of each switch.
While the Polaris Gray and Purple Star switches have distinct housing materials for their top and bottom housings, they both ultimately aim to provide a unique and satisfying typing experience for users. The Polaris Gray's polycarbonate housing creates a sharp and clear sound profile, while the Purple Star's POM housing offers a deeper and more muted sound. Despite their differences, both switches prioritize sound quality and tactile feedback through their choice of housing materials, ensuring that users will be able to find a switch that best suits their preferences.
Weight
The SP-Star Polaris Gray linear switch has a bottom out force of 67 grams, which is considered medium-heavy, while the KTT Purple Star linear switch has a lighter bottom out force of 50 grams. The actuation force of the Polaris Gray is not specified, whereas the Purple Star has an actuation force of 43 grams, making it lighter compared to the Polaris Gray. For those who prefer a lighter typing experience, the KTT Purple Star may be more suitable, allowing for longer typing sessions with less fatigue. However, for users who prefer a more substantial typing feel with a heavier push, the SP-Star Polaris Gray would be the better choice. Ultimately, the actuation and bottom out forces of each switch play a significant role in determining the typing experience and comfort level for the user.
