Kailh Plum vs. Gazzew U4

Overview

When it comes to choosing a mechanical keyboard switch, two options that stand out are the Kailh Plum and the Gazzew U4. Both switches fall into the tactile category, but they offer distinct features that set them apart. The Plum is known for its unique combination of weightiness and a moderate tactile bump. Unlike many other tactile switches, the Plum doesn't compromise on tactility even with its hefty feel. Additionally, it has a neutral sound profile that is enjoyable to the ears. On the other hand, the Gazzew U4 offers a sharp and exhilarating tactile bump that adds a sense of excitement to your typing experience. Beyond that, it surprises with a plush, felt-like sensation when bottoming out. The U4s also boast a whisper-quiet sound profile, adding an element of subtlety to their style. However, let's dive in a bit deeper beyond these generalities so you can best decide on the ideal switch for your needs.

Housing materials

The housing materials of the Kailh Plum and the Gazzew U4 switches have noticeable differences that contribute to their overall sound profiles. The Plum switch's polycarbonate top housing creates a sharper, higher-pitched, and crisper sound, thanks to its relatively stiffer plastic. This material is especially beneficial for those who plan to use RGB lighting, as its translucency allows for enhanced lighting effects. In contrast, the Gazzew U4 features a proprietary Gazzew blend top housing, also known as "boba plastic," which delivers a rich and deep sound profile due to its softness. This softer plastic enables the switch to produce a more resonant and mellow sound.

When it comes to the bottom housings, the Plum switch uses nylon, a classic switch housing material known for eliciting a deeper and fuller sound profile. Nylon's relatively softer plastic absorbs more sound, resulting in a duller and rounder sound from the switch. On the other hand, the Gazzew U4 utilizes its proprietary Gazzew blend bottom housing, which, like the top housing, delivers a rich and deep sound due to its softness. Both switches benefit from the softness of their bottom housings, contributing to a more pleasant typing experience with reduced noise.

Although the housing materials differ between the two switches, the impact each material has on the switch's overall sound profile is split between the top and the bottom. Pressing down on a switch will emphasize the qualities of the bottom housing, influencing the bottom-out sound and feel. Conversely, releasing a key will highlight the impact of the top housing on the sound produced. Despite these differences, both switches strive to create an enjoyable typing or gaming experience with their respective housing materials, allowing users to find a switch that aligns with their preferences.

Weight

When considering the actuation force and bottom out force of the Kailh Plum tactile switch and the Gazzew U4 tactile switch, there are some notable similarities and differences. Starting with the actuation force, the Kailh Plum switch unfortunately has an unavailable grams measurement, while the Gazzew U4 switch requires 43 grams of force. This indicates that the Gazzew U4 is lighter in terms of actuation force. Moving on to the bottom out force, the Kailh Plum switch requires 70 grams, which is medium-heavy, while the Gazzew U4 requires 62 grams, placing it in the medium category. Therefore, it can be observed that the Kailh Plum switch is heavier in terms of bottom out force.

Considering the weight of the switches, it is important to note that some individuals prefer lighter switches as this allows them to type for longer periods without experiencing fatigue. This aspect is particularly beneficial for those who use their keyboards extensively for work or indulging in long gaming sessions. On the other hand, there are users who prefer a stronger push feel, seeking a more substantial typing experience. For such users, switches with heavier forces are more suitable.

In the case of individuals looking for a lighter actuation force, the Gazzew U4 would be the preferred choice as it requires 43 grams, whereas the Kailh Plum's actuation force is unknown. However, for those seeking a heavier bottom out force, the Kailh Plum switch would be the better option, with its 70-gram requirement. Nevertheless, for individuals seeking a medium force for both actuation and bottom out, both switches provide a similar experience, with the Gazzew U4 requiring 43 grams for actuation and 62 grams for bottom out.

Both the Kailh Plum tactile switch and the Gazzew U4 tactile switch have a travel distance of 3.6 mm. This means that when you press down on a key equipped with either of these switches, you will feel the same distance being traveled from the top to the bottom. Therefore, in terms of travel distance, both switches will provide similar results.
