Housing materials

The Outemu Lime and the Gazzew U4T switches have different housing materials that contribute to their unique sound profiles. The Lime utilizes a nylon top housing, which is a classic switch housing material known for producing a deeper and fuller sound. The softer nature of nylon allows it to absorb more sound, resulting in a duller and rounder sound when typing. In contrast, the U4T features a proprietary Gazzew blend top housing, often referred to as "boba plastic." This blend delivers a rich and deep sound profile due to its softness. Although both switches aim to produce a similar effect of a deeper sound, they achieve this through different housing materials.

Similarly, the bottom housings of the Lime and the U4T switches differ in material, further influencing their sound profiles. The Lime uses a nylon bottom housing, which contributes to its deeper and fuller sound. Nylon, being a softer plastic, absorbs more sound than harder plastics, resulting in a different tactile and auditory experience when typing on the Lime. On the other hand, the U4T employs a proprietary Gazzew blend bottom housing, which also offers a rich and deep sound profile due to its softness. Both switches' bottom housings play a significant role in the bottom-out sound and feel of the switches. While the materials may differ, their objective of enhancing the overall typing experience remains consistent.

Considering the impact of both top and bottom housings on the switch's sound, the Lime and the U4T will produce distinct auditory experiences when pressing and releasing keys. The top housing of a switch has a more significant influence on the sound when a key is released, making it crucial for achieving a specific sound profile. Despite their differing materials, both the Lime's nylon top housing and the U4T's Gazzew blend top housing aim to contribute to a rich and deep sound when keys are released. Conversely, the bottom housing of a switch affects the sound and feel during bottoming out a key. While the Lime and the U4T utilize different materials for their bottom housings, both strive to provide a deeper and fuller sound during typing. Therefore, although the housing materials of the Lime and the U4T may diverge, their ultimate goal is to offer a satisfying and immersive typing experience when used.

Weight

When comparing the actuation and bottom out forces of the Outemu Lime tactile switch and the Gazzew U4T tactile switch, it is clear that there are notable differences between these two options. The Lime switch has a light actuation force of 35 grams, meaning it requires a relatively gentle push to register a keystroke. Additionally, it has a slightly heavier bottom out force of 45 grams, providing a bit more resistance when fully pressed down. On the other hand, the exact actuation force of the U4T switch is unknown, but it has a medium bottom out force of 62 grams. This indicates that the U4T switch requires a slightly stronger push to trigger a keystroke compared to the Lime switch. In terms of weight, the Lime switch can be considered lighter, making it a suitable choice for those who value longer typing sessions or extended gaming sessions. In contrast, the U4T switch offers a more substantial typing experience with its heavier forces, which may be preferred by users seeking a stronger push feel. Overall, while the Lime switch has a lighter actuation force and a slightly lighter bottom out force than the U4T switch, both switches can provide similar results for those who desire specific key forces.

Travel distance

When comparing the travel distance of the Outemu Lime tactile switch and the Gazzew U4T tactile switch, it is clear that they differ in this aspect. The Lime has a travel distance of 3.3 mm, making it shorter than the traditional 4.0 mm distance. On the other hand, the U4T has a travel distance of 4 mm, aligning more closely with the traditional measurement.

For those who prioritize faster response times, the Lime with its shorter travel distance may be the preferred option. Gamers, in particular, tend to favor shorter travel distances for quicker reactions during gameplay. However, it is important to note that some individuals find short travel distances to be too abrupt or lacking in depth. In this case, the U4T with its longer travel distance might be a more suitable choice, providing a greater sense of key depression.

Ultimately, the choice between these switches hinges on personal preference and the desired typing experience. For a more responsive and snappy feel, the Lime can deliver similar results to the U4T despite its slightly shorter travel distance. However, for those who prefer a more substantial keystroke, the U4T's longer travel distance would likely be the better option.
