Comparison Aula S75 Pro Star Vector Switch vs Attack Shark K86

The length of the cable that the keyboard is equipped with for wired connection (see "Connection type").

When choosing this parameter, you should first of all take into account the distance from the device to the connection port: a cable that is too short may simply not reach the connector, and a cable that is too long may get confused at hand and create inconvenience. As for specific values, the reference length is 1.8 m. However, there are cables both shorter and longer.

— 100% (full-sized). Classic layout with 104/105 keys featuring a full NumPad, dedicated F1–F12 row, and navigation cluster including Insert/Delete, Home/End, PgUp/PgDn; this version is valued for its familiar geometry, typing speed, and ease of frequent number entry, making it optimal for work in Excel, accounting, IDEs, and editing programs, while in games, the NumPad is often used for binds and macros; compared to TKL/80% without a numeric block, as well as 96% and 1800-compact, the 100% format offers maximum comfort and requires less retraining, but takes up more desk space and pushes the mouse further away, so for compact workplaces, it might be wiser to consider smaller formats.

— 1800 (compact full-sized). A full-featured layout with a numeric block but in a narrower body: the NumPad is shifted closer to the main field, and navigation is often placed above it or compacted next to the arrow keys. It feels like "100%", but is shorter by a few centimeters, so the mouse is closer to the center, offering more comfort for wrists. Compared to TKL, you retain fast number entry, and against 96%, you gain a slightly more "airy" geometry with clear orientation. Note the non-standard sizes of some keys and the right block, which sometimes require special keycap sets. This format is convenient for Excel, accounting, IDEs, and editing, while offering gamers the NumPad for macros while saving desk space.
...r> — 96% (compact full-sized). Keyboards that preserve all key zones of 100% (F1–F12 row, arrow keys, navigation, and NumPad) but place them in a tight "grid" layout, almost like TKL in width. The numeric block is shifted closer to the main area, while Insert/Home/End and PgUp/PgDn are often reduced to 1u and grouped above the arrows or next to the NumPad. Compared to the 1800 format, 96% is even more compact and visually "smoother," and against TKL, you do not lose the speed of number entry. Note the possible non-standard sizes of the right shift, zeros, and plus on the NumPad, requiring a more selective keycap choice. This format is chosen for Excel and accounting, editing and coding, while gamers use the NumPad for macros, gaining maximum functions with minimal table width.

— 80% (TKL, without Num-block). A full-featured keyboard without a numeric block: retains the F1–F12 row, arrow keys, and navigation Insert/Delete, Home/End, PgUp/PgDn, but is considerably narrower, bringing the mouse closer to the center, which is easier on the shoulders and wrists. Gamers and developers favor this format: there’s more desk space, while familiar keys and hotkeys remain in place. Compared to 100%, you only lose quick number entry, which can be supplemented with a separate wireless NumPad. In comparison to 75%, TKL is more readable and "airy" thanks to its separate navigation block; unlike 96%, it is more compact for mouse grip, though lacking a NumPad. The 80% (TKL) format is optimal for FPS, work in IDEs, editing, and everyday office tasks where numbers aren’t entered continuously.

— 75% (compact TKL, without Num-block). "Almost TKL," where all main keys are within reach, but the body is shorter by several centimeters due to a tight "staircase" arrangement of arrows and navigation. Compared to 80%, it decreases the distance between hands and mouse, enhancing ergonomics for prolonged use, and relative to 100% and 96%, you lose only the numeric block, gaining space for the mouse and a more neutral shoulder posture. This format is chosen for IDEs and design packages, FPS and MOBA, mobile setups with narrow desks, when numbers are entered infrequently or supplemented with an external NumPad. Note: 75% may have non-standard sizes in the right block and individual keys, which is important when selecting keycaps and stabilizers.

— 65% (ultra-compact, without F-row). "Condensed TKL": the alphanumeric block, arrow keys, and a pair of navigation keys remain in place, while the NumPad and the top F1–F12 row are accessed via Fn. This layout is significantly narrower in width, moving the mouse closer to the center, which reduces the spread of arms — ideal for narrow desks, when working on a laptop, and for travel. Compared to 60%, the 65% format is more practical thanks to dedicated arrows and Delete; against 75% and 80%, it is more compact but often requires getting accustomed to layers. Possible non-standard sizes of the right shift and navigation keys are important when choosing keycaps. In real-world scenarios, the 65% format is excellent for IDEs, streaming, and FPS/MOBA games, while regular number entry is complemented by an external wireless NumPad.

— 60% (mini). Classic "trimmed" layout with ~61/62 keys without NumPad, no F1–F12 top row, and no separate navigation cluster: all accessed through the Fn layer, with arrows usually assigned to combinations. Compared to 65%, this format is even more compact but often requires acclimatization to layers; against 75%/80%, you save desk width and achieve a more neutral shoulder posture, at the cost of losing "quick" F-keys. The strong points of 60% are portability, free space for the mouse and mat, and reduced arm movement between keyboard and mouse, making it popular with FPS gamers, streamers, and those working on laptops at narrow desks or traveling. If active number entry or "hot" F-keys are needed, an external wireless NumPad and well-thought-out layer layout help.

— 40% (ultra-mini). Radically compact layout with about 40–50 keys, lacking a number row, arrows, and F-keys: all are accessed via Fn layers, combined presses, and macros, often with an ortholinear matrix. Due to the minimal width, the mouse is closer to the center, reducing hand spread and freeing up desk space, appreciated by mobile users and minimalists. Compared to 60% and 65%, the 40% format requires more serious adaptation and thoughtful firmware (QMK/VIA, home-row mods, tap-dance), and keycap selection is more challenging due to non-standard sizes. The strong point is portability and speed after getting used to it; weakness — reliance on layers and inconvenience of frequent number entry and arrow navigation. The 40% format is practical for travel, work on laptops with docking stations, text editing with hotkeys, and streaming, while numbers are usually supplemented with an external NumPad.

The model of switches (switches) used in the keyboard - switching mechanisms installed under each individual key. These details are given if the design uses advanced mechanics, positioned as a better option than traditional switches. Mostly gaming keyboards are equipped with such mechanics.

The most popular switch brands in our time are Cherry MX, considered the "classic of the genre" for high-quality mechanics; Gateron, practically not inferior to him; not so advanced, but also cheaper Kailh and Keychron, as well as ultra-budget Outemu. For all these brands, different types of switches have a different stem color, which can be used to determine the features of the keyboard. It is also worth saying that modern mechanical switches are divided into three main varieties: linear, tactile and clicky.

- Linear. Such solutions are closest to conventional membrane keyboards: the key travel is uniform along the entire length, with minimal resistance and the absence of a clear actuation point. There is an opinion that the linear "mechanics" is best suited for games where you have to deal with fast and frequent clicks; however, in practice, this moment largely depends on the personal tastes of th...e user, nothing prevents the use of such keyboards for working with texts.

- Tactile. Switches with a clearly defined actuation point - a kind of barrier to the path of the key. Such a "barrier" allows you to clearly determine by touch whether the key has worked or not. Tactile keyboards are valued primarily by tech who have to type large volumes of texts.

- Tactile-auditory (Clicky). In such switches, the actuation point is felt not only by touch, but also by ear: the actuation of the key is accompanied by a clearly audible click, which is often compared to the sound of the keys of a typewriter. Due to this, this option is also very popular among users dealing with texts. Some people consider switches of this type not very suitable for games, since they are supposedly not very convenient for frequent, fast pressing; however, a quality Clicky switch is as good as a linear switch in this regard, and the choice depends solely on personal preference. But the unequivocal disadvantages of such keyboards include a rather loud click sound, which in some situations may be superfluous.

As for specific colors, here are their features:

- Red (red). Linear type switches with minimum resistance. They are popular, in particular, among professional gamers who deal with dynamic games and try by all means to speed up their reaction to gaming events. On the other hand, a low force increases the likelihood of accidentally pressing an unnecessary button.

— Black. Another type of linear switches. They have a tighter move compared to Red, which, on the one hand, requires a little more effort, on the other hand, minimizes the chance of accidentally pressing the wrong key.

Blue. Switches in clicky format, with tactile feedback and a click.

— Brown. Switches with tactile feedback, but no "click". The Brown action is great for when you want a keyboard with tactile feedback and at the same time you want to avoid unnecessary noise (although the sound is still louder than on a membrane keyboard). In addition, it is considered a good option for tech who are just starting to get acquainted with mechanical keyboards.

— Silver. Linear switches designed for maximum operating speed. They have a very low stroke - about 1 - 1.2 mm - as well as a very small pressing force, which contributes to high speed. At the same time, the use of such a keyboard requires a certain skill, since even a small effort from an accidental touch usually leads to the operation of a key.

The force required for the complete actuation of the switch under the key. This parameter is measured in grams and directly affects the feel of typing or gaming. Light switches with a force of about 35 – 45 grams require minimal pressure and are suitable for fast typing, while heavier ones — 55 – 80 grams — provide a precise response and prevent accidental presses. Actuation force is considered one of the key characteristics of mechanical keyboards, as it determines user comfort and individual preferences.

The distance a key travels from its initial position to the point of actuation by the switch. Usually measured in millimeters, it ranges from 1 to 2 mm in gaming models and around 2 – 2.5 mm in standard mechanical keyboards. A shorter travel distance provides quicker response and is suitable for dynamic gaming, while a longer distance offers a more pronounced tactile feel and reduces the risk of accidental key presses. This parameter is important for selecting a keyboard based on specific tasks and personal preferences.

The total distance that a key travels from its top position to the switch base. Usually, the total travel ranges from 3.5 to 4 mm for classic mechanical keys and can be less in low-profile models. This factor affects the depth of the press and overall feel of operation: a short travel allows for quicker responses and reduces fatigue, while a longer travel provides a distinct tactile feedback and the sensation of a "full" click. The choice of optimal total travel depends on the typing style and preferences of the user.

Keyboard switch durability is measured by the number of presses the keys can withstand before they begin to show signs of wear or malfunction. Switches can have a lifespan of several million to tens of millions of clicks. In laboratory conditions, this parameter is checked using special testing machines, which diligently press the keys the required number of times, on the basis of which a verdict is made regarding the approximate service life of the switches.

The frequency with which the computer polls the keyboard to determine which keys are currently being pressed. The parameter is measured in Hertz (Hz) - they show how many requests are executed per second. Higher Hertz means keystrokes are detected and registered faster. This can provide an advantage in games and tasks that require the highest possible input speed.

As for specific values, for most ordinary users the standard polling rate of 125 Hz will be quite sufficient. Gaming keyboards can have a frequency from 1000 Hz (keystrokes in this version are recorded every 1 ms), and advanced models for true e-sportsmen - up to 8000 Hz (the reaction time is 0.125 ms).

Keycaps made from polybutylene terephthalate (PBT), one of the toughest and most durable plastics for keyboards. Unlike ABS keycaps, they are more wear-resistant, do not become glossy over time, and are resistant to mechanical abrasion. This durability is also aided by high-quality symbol application methods, such as double-shot molding or laser engraving. PBT keycaps have a textured surface that feels pleasant to touch and provide a clearer and more tactile feedback when typing.
