KTT Lightning vs. Gazzew U4

Overview

When it comes to mechanical keyboard switches, two popular options that offer unique experiences are the KTT Lightning, a linear switch, and the Gazzew U4, a tactile switch. The KTT Lightnings are renowned for their "speed" switches, making them the go-to choice in situations where split-second decisions matter the most. Typing on these switches provides a smooth and slick feel, accompanied by a distinct clacky sound profile. On the other hand, the Gazzew U4 switches offer a different experience altogether. With a sharp and exhilarating tactile bump, typing on the U4 switches delivers an unexpectedly plush and felt-like bottom-out sensation. Not only do these switches provide style and subtlety, but they also boast a sound profile that is whisper quiet. However, let's dive in a bit deeper beyond these generalities so that you can make an informed decision on which switch is best suited for your needs.

Housing materials

The KTT Lightning and the Gazzew U4 differ in terms of their housing materials. The Lightning utilizes a polycarbonate top housing, while the U4 employs a proprietary Gazzew blend top housing. Polycarbonate is a stiffer plastic that creates a sharper and crisper sound profile, making it ideal for those seeking a higher-pitched sound. On the other hand, the Gazzew blend top housing, often referred to as "boba plastic," delivers a rich and deep sound profile due to its softness. It provides a more mellow and rounded tone, appealing to those who prefer a deeper sound experience. So, while the materials yield contrasting sound profiles, both options can deliver satisfying results depending on the user's sonic preferences.

In terms of their bottom housings, the Lightning features a nylon material, while the U4 utilizes the proprietary Gazzew blend. Nylon, being a softer plastic, absorbs more sound and creates a deeper and fuller sound profile. This makes typing on switches with nylon bottom housings a more immersive experience with a duller and rounder sound. The Gazzew blend bottom housing, similar to the top housing, contributes to the "boba plastic" sound signature, providing a rich and deep sound due to its softness. Both options offer distinct acoustic qualities, allowing users to choose the type of sound profile they desire from their typing experience.

When it comes to the overall feel of the switch, the qualities of the top and bottom housings play a role. The bottom housing has a more significant impact on the bottom-out sound and feel when the switch is pressed, as it determines the level of resistance and response during the key press. Conversely, the top housing influences the sound produced when a key is released. Thus, the choice of housing materials for both top and bottom will have a noticeable effect on the overall feel and sound quality of the switch. Whether opting for the stiffer polycarbonate top housing of the Lightning or the softer Gazzew blend top housing of the U4, users can expect differences in sound and tactile feedback. However, in terms of achieving similar results, both switches prioritize providing a distinct and satisfying sound profile in their respective designs.

Weight

When comparing the actuation force and bottom out force of the KTT Lightning linear switch and the Gazzew U4 tactile switch, there are some notable differences. The Lightning switch has a relatively lighter actuation force of 43 grams and a bottom out force of 50 grams. In contrast, the U4 switch shares the same actuation force of 43 grams, but has a slightly heavier bottom out force of 62 grams.

For individuals who prefer a lighter typing experience, the Lightning switch would be a suitable choice, as its lower actuation and bottom out forces provide a smooth and effortless keystroke. This can be particularly beneficial for prolonged typing sessions or intense gaming sessions where fatigue may become a concern. On the other hand, the U4 switch offers a more substantial typing experience, suitable for those who appreciate a stronger push feel. With its higher bottom out force, the U4 switch provides a satisfying level of resistance that can enhance the tactile feedback during typing.

Although the actuation forces of both switches are the same, the contrasting bottom out forces result in different typing experiences. The Lightning switch provides a consistent light touch throughout the keystroke, while the U4 switch offers a slightly more tactile and weighted feel during the bottoming out process. However, both switches can still offer similar results in terms of actuation, ensuring that keystrokes are registered reliably and efficiently. Ultimately, the choice between these switches will depend on personal preferences, with the Lightning switch being the lighter option and the U4 switch offering a slightly heavier typing experience.

Travel distance

The KTT Lightning linear switch has a travel distance of 3 mm, while the Gazzew U4 tactile switch has a travel distance of 3.6 mm. Both switches have a shorter travel distance compared to the traditional 4.0 mm, making them suitable for those who prefer a faster response time. Gamers, in particular, tend to favor shorter travel distances. However, if you prefer a more substantial feeling when pressing down on a key, the Gazzew U4 tactile switch with its longer travel distance may be more suitable. It is important to consider personal preferences when choosing between these switches, as the shorter distance of the Lightning may feel more abrupt to some users. Ultimately, the choice between the two switches depends on the desired level of depth and responsiveness.
