Mechanical keyboards

We all have long been waiting for the mass appearance of all kinds of cyber gloves and virtual reality at every turn, but still, every day in the office and at home we have to work on such a commonplace thing as a regular keyboard.

And since you come across a thing regularly, the question gradually arises - is it possible to find some more convenient options for conventional keyboards for work?

So, some time ago I attended to collecting information about keyboards, and even started to prepare information for the article, but unfortunately (fortunately?) There was an exhaustive article about all the nuances at once, which I decided to translate.

Mechanical keyboards. Guide.


Fact: Almost all modern keyboards that you see around you are membrane keyboards. The technology is similar to that used in cheap remotes from the TV. Manufacturers make keyboards as cheap as possible to make big profits. Yes, not excluding the expensive “gaming” and “designer” keyboards. But why use what was originally done as cheap stuff?

So, why do you need a mechanical keyboard?
Most of those who have tried working with a mechanical keyboard claim that the sensations speak for themselves. On the keyboard that you are currently sitting at, you need to press the key to the very end until it rests against the membrane so that the keyboard registers the press. This requires a certain amount of effort, your fingers get noticeably tired and the impression remains that you have been tapping the whole piece of plastic all day. The mechanical switches in the keys work in such a way that pressing the key works before the button is pressed “all the way”, so that you do not spend unnecessary forces on swotting. And with various types of buttons you can choose the most comfortable efforts and sensations from keystrokes. Many of those who once worked on a mechanical keyboard will never want to return to their usual membrane keyboards.

NB It is also worth noting that mechanical keys are much more reliable than membranes, for example, for Cherry MX keys, the manufacturer claims 50 million keystrokes. This is one or two orders of magnitude greater than membrane keyboards.

Terminology


Locking keys (Key Blocking) and dummy pressed (Ghosting)
Fictitious press - is when you press two keys on the keyboard, and the third, you do not press, still works. On modern keyboards, this has ceased to be found, even on the cheapest ones, because manufacturers have made corrections and blocked the operation of such combinations.

Locking keys (Key Blocking) - is blocking the operation of the new keys when you have already pressed the maximum amount allowed for this keyboard model. So if you pressed two keys at the same time, and pressing the third does not work, then you definitely have a keyboard that processes only 2 keys at a time (2 Key RollOver = 2KRO).

Number of simultaneous keystrokes (Key Rollover, "#KRO" and "NKRO") The
non-lockable "NKRO" keyboards are when you can simultaneously press as many keys as you want, and all keystrokes will be sent to the computer. Some manufacturers of "gaming" keyboards incorrectly called such keyboards "anti-ghosting". And even Logitech and Razer gaming keyboard makers only unlock a small block around the WASD keys. It is worth noting that only keyboards connected via PS / 2 can work in fully non-blocking mode (NKRO); and only keyboards from Microsoft and Ducky are the only two manufacturers that operate NKRO via USB.
(#KRO, where instead of "#" any digit is the maximum number of simultaneously processed clicks)

Most mechanical keyboards when connected via USB are marked as 6KRO, meaning that six keys can be pressed simultaneously. This should be enough for most users, but in some games (especially when playing a split-screen) and six keys, it may turn out to be not enough.
USB keyboards with 6KRO also allow you to press up to a maximum of 4 modifier keys with six regular keys. Modifiers are CTRL, ALT, Shift, and Win.

Bounce keys (Key Bouncing)
All types of keys, including membrane keys, have a chatter. When you press a key and the contacts begin to touch, the keyboard controller begins to register a lot of key press / release operations. In order that with a single press you would not get a full screen filled with a single letter, small pauses are used in the controllers. The controller waits a few milliseconds to eliminate the bounce and only then sends clicks to the computer. In mechanical keyboards, the time required to avoid chattering is noticeably shorter, for example, when using Cherry MX switches, a delay of 5ms is sufficient, while membrane keyboards require significantly longer pauses (depending on the quality of manufacture - the worse the keyboard, the greater pauses).

Polling frequency(Polling Rates) and response times (Response Times)
While the polling rate is a significant indicator for the mouse and directly affects the smoothness / accuracy of the cursor, these parameters are useless for the keyboard. Let's imagine that all buttons have a 5ms response delay (which is close to ideal conditions). Even if you are a superman, each press will still be delayed for at least 5ms. So the actual polling frequency of more than 200 hertz is absolutely useless. Even more harmful, because You overload the processor with frequent and useless keyboard polls. In contrast to the USB connection, the keyboards included in the PS / 2 are not interrogated at all, they send a signal when a press occurs, which creates a hardware interrupt, and the processor notices the press.

PS / 2 or USB ?
PS / 2 wins on all counts: First, it supports an unlimited number of simultaneous clicks (full n-key rollover). Second, PS / 2 do not require constant polling, but use hardware interrupts. Thirdly, there is no chance that keystrokes will be delayed due to overload of the USB bus with other devices. There are two types of USB data transfer: interrupt-based (the USB controller constantly polls the keyboard when the key is pressed, the USB controller sends the interrupt), and the isochronous transfer mode when a certain part of the bus bandwidth is reserved to ensure there are no delays. Unfortunately, the second mode requires a special controller, and is not used in any membrane keyboard just because of the price.

So if you have both PS / 2 and USB, there is no reason not to use a PS / 2 connection.

Main buttons


Button, but not “just a button”

Many people ask which buttons are better, without thinking about what exactly you want to get in the end. Fortunately, this is not a problem, since most mechanical buttons still give a noticeably better feel than any membrane keyboard. Nevertheless, the final choice is still important, because the button is not just a button, it is the heart of the keyboard that should suit your personal taste. If you don’t like the feel of pressing a key, you won’t like working on the keyboard.

The response force of buttons is usually measured in grams (g), although in reality the force is measured in centiNewton (cN), but the weight of 1 gram presses down with a force of almost 0.01 Newton. So it’s customary to write “55g” meaning a force of 0.55 Newton, for simplicity, although this is not entirely correct.

Cherry MX black
Type: Even pressing (Linear)
Tactile: No
Clicky: No
Actuation Force: 60g (average 40g-80g)
Depth of pressing (Key Travel): 2mm to trigger, 4mm to the stop

Cherry buttons MX Black - even pressing, no click and tactile sensations. It is considered one of the best buttons for games. When you play, the tactile sensation gives almost nothing, because the key is always pressed “all the way”. So these keys are very soft. The moment of operation and release is on the same level, so they are great for games where many frequent clicks are required. But you will not get pleasure from typing on this keyboard, precisely because of the uniform pressure of pressing.
          

Cherry MX brown
Type: Tactile pressing
Tactile: Yes
Click: No
Trigger strength: 45g (55g at the peak)
Depth of depression: 2mm to trigger, 4mm to the stop

Cherry MX Brown buttons represent a balance between the game keys and the keys for typing. They have a tactile feel in the middle of pressing, so you always feel the moment when the button worked. After that, you can immediately release the key. Keys can also be attributed to gaming, because the trigger and release times are located close enough to each other, so you can feel for this point to perform high-speed shooting in games.
          

Cherry MX blue
Type: Tactile with a click
Tactile: Yes, neat
Click: Yes
Force: 50g (60g at the peak)
Depth: 2mm before operation, 4mm all the way

Cherry MX Blue buttons are considered ideal for typing. The tactile feel is very well felt, and the force of pressing is comparable to the "ordinary" keyboards.

Many say that these keys are good for games, too, but their trigger point is noticeably lower than the release point, so it will be harder to shoot quickly.
          

Cherry MX clear
Type: Tactile pressing
Tactile: Yes
Click: No
Trigger strength: 55g (65g at the peak)
Depth of depression: 2mm before triggering, 4mm all the way

Cherry MX Clear keys are usually called "hard browns" because they have a stronger tactile feel than “Brown”. But this is a rather subjective feeling, nevertheless, these are one more balanced keys. The force of pressing is comparable to the force of “ordinary” membrane keyboards, with a pleasant tactile sensation of operation. Few keyboards use this type of button.
          

Cherry MX red
Type: Even pressing
Tactile: No
Click: No
Trigger strength: 45g
Depth of depression: 2mm before triggering, 4mm all the way

Cherry MX Red buttons are another version of the game buttons. This is a lighter version of the MX Black, with less trigger effort. Many people don’t like this type for typing or even for games, because pressing is very easy. Some sources indicate that this type is deprecated, although some keyboard manufacturers still use them.
          

Keys with a bending spring (Buckling Spring):
Type: Mechanical with tactile sensation and click.
Tactile: Yes, very precise.
Click: Yes, strong.
Force of operation: 65g-70g
Depth of pressing: 2.3mm before operation, 3.7mm to the stop

Keyboards with a snap spring are rather strange when you look at the principle of operation. After pressing to a certain point, the spring under the key bends, abutting against the wall of the key, and forcing the mechanism in the form of a hammer to press the membrane from below. The keys have a tactile feel and click. Perhaps the only keyboards where the depth of response exactly matches the tactile feel.
          


Black alps
Type: Mechanical with tactile sensation
Tactile: Yes
Click: No
Response force: Simplified 60g, Complicated 70g
Depth of pressing: 3.5mm

One of the two types of the most common buttons from Alps. Many people do not like these keys, because they are hard, pressed tightly closer to the bottom, and as the wear and tear the friction of the key mechanism increases markedly. However, they are still better than any membrane keyboards.
There are two types of Black Alps buttons. The older ones are known as “Complicated” due to the large number of parts, and the new ones are “Simplified”. Are made by Alps and some other companies. Fukka is best known for releasing “new” buttons.
          

White alps
Type: Mechanical with a tactile sensation and a click.
Tactile: Yes
Click: Yes
Response force: 60g-70g
Depth of pressing: 3.5mm

The most common Alps buttons are White Alps. They are more popular than Black, due to a sharper tactile feel and less pressing effort. Like the Black Alps, they are harder to press at the end of the press, compared to other mechanical keys.
Like Black, there are versions of “Complicated” and “Simplified”.
There are also many buttons like White Alps of various quality. Some, for example SMK Monterey, are quite pleasant.
          

Topre
Type: Tactile capacitive buttons
Tactile: Yes
Click: No
Response force: 30g, 35g, 45g, 55g depending on the model
Depth of pressing: 4mm

Topre keys are not quite mechanical, rather a hybrid, they are capacitive by nature. They use a spring and a rubber in the form of a hemisphere, pressing the spring changes the capacitance of the contacts of the substrate. A change in capacitance causes a trip.
Topre keys are considered the best keys of all, they are convenient for typing, and noticeably quieter than Cherry MX, Alps or Buckling Spring.
They have the most uniform pressure, even compared to Cherry MX Red and MX Black.
          


Keycap (Keycap). Plastic and design


Plastic

Two types of plastic for key covers are mainly used: ABS and PBT. Each has its own nuances, but overall PBT is better than ABC:

Plastic PBT (Polybutylene Terephthalate)
  • Withstands up to 150 * C (and sometimes more)
  • More durable
  • The top face is not erased and does not glare
  • Dear


ABS plastic (Acrylonitrile Butadiene Styrene)
  • Soluble in solvent
  • The top face is more quickly erased to shine and begins to glare
  • Cheaper
  • Easier


Top Type:

Cylindrical - almost all keyboards today use this type.


Flat - mainly found on laptops.


Scope - Usually used in various rare technology and typewriters.


Keyboard Type

Printing / Pad Printing

This view can be found on 90% of keyboards. Cheap and easy. The letters are applied as if on stickers, and they can be felt a little with a finger by swiping a key.
Pros:
  • Cheap
  • Multicolor
  • You can type on any edge of the key.

Minuses:
  • Feels under the finger
  • Quickly erased


Laser Burning / Laser Etching

Speaks for itself. The letters feel a little scratched. Works best on white buttons, as black is just the color of burnt plastic. On black buttons, the place has to be filled with some kind of paint.
Pros:
  • Long not erased

Minuses:
  • Application felt
  • Low clarity


Sublimation / Dye Sublimation

Sublimation provides a better option than the above. the paint penetrates into the plastic to a certain depth inside and does not wear off even with intensive use, the letters remain as new. Unfortunately, due to the price, very few firms use this technology.
Pros:
  • Not erased
  • Fingerless application
  • One button multicolor lettering
  • Drawing on any edges of buttons
  • Well distinguishable

Minuses:
  • Expensive
  • Printing is possible only with colors darker than plastic. it is impossible to print white letters on black plastic.


Double Injection Molding / Duble-shot Injection Molding The

key consists of two parts, the upper part with the letter holes cut out in it and the lower part with corresponding protruding parts.
This method gives the best quality buttons possible. The edges of the letters are perfectly clear and give the greatest contrast. Unfortunately, due to the price, only a few manufacturers make such keys (TG3 Electronics).

The easiest way to verify that you have double-casting keys is to look at the key from below, it should be clear that it consists of two types of plastics of different colors.


Pros:
  • It is not erased. Never
  • Clear boundaries
  • High contrast and visibility of inscriptions.

Minuses:
  • The most expensive
  • Two color limit per key
  • On heavily worn keys, you can sometimes feel the edges of plastics.

Button Cover Replacement and Maintenance


Key covers are easy to remove, you can do it yourself:
  • Paper clip
  • Flat screwdriver
  • Knife blade
or buy special grips:


The key cover mounting sockets are universal, so you can always replace part or all of the covers with the ones you like in a different color or paint existing ones yourself , making your keyboard really unique and to your taste. On sale you can find ready-made sets of different colors and with different symbols (Windows / Mac / Linux / Blank / Symbols):

Cherry MX
Alps
Topre


Чистка


Sometimes you want to clean your keyboard. There are many cleaning options, and you can choose any one, spending from a couple of minutes to several hours, depending on what kind of dirt you have to remove and what exactly to clean. If you just poured a glass of Pepsi onto the keyboard, you read what you need.

It’s a good idea to have a DataVac type vacuum cleaner on hand, because they have a blow mode (or compressor).

Quick cleaning
Keyboards clog up with dirt pretty quickly. Indeed, few of us wash our hands before each computer work. And there is always dust and hair that fall into the keyboard through the gaps between the keys. So it’s a good idea to clean the keyboard at least once a month.

1. Blow out dirt from under the keys with a vacuum cleaner or compressor.
2. Wipe the keys and the keyboard body with a clean cloth moistened with alcohol.
Caution: Alcohol must not be used with some keyboards (for example Filco), it can damage the key labels.
3. If you are a heavy smoker, the plastic on your keyboards can turn yellow quickly enough. We recommend wiping the yellowness with Windex-type products (glass cleaner with ammonia, analogue “Mr. Muscle”).

Keep the keyboard clean and it will be pleasing to the eye for a long time.

Great cleaning
If you just bought a used keyboard on ebay and it looks like you spent your life in a car workshop, or spilled your tea on the keyboard, you need serious cleaning. Do not forget that liquids should be removed as quickly as possible, the longer you wait, the less chance that the keyboard will survive.

1. Remove the key covers from the buttons.
2. Open the keyboard case and remove the button board.
3. If you do not have a dishwasher, or you decide not to use it, then lower the keyboard body and key covers into warm water with detergent. Let them soak for half an hour.
4. The cleaning of the button board itself is different for different types of buttons.
  • Кнопки Cherry, Alps, и другие аналогичные: Поместите всю плату с кнопками в дистиллированную воду. Слегка поболтайте плату, что бы вода могла очистить внутренности самих кнопок. Теперь надо попытаться высушить ее, трясите плату до тех пор, пока из нее не перестанет литься вода. Потом переверните плату клавишами вниз, что бы влага не скапливалась на плате и оставьте сушиться над теплом. Можно использовать фен, только не нагревайте одну точку слишком долго, пластик может начать плавиться. Компрессором можно выдуть всю влагу очень быстро.
  • Мембранные клавиатуры, в том числе с изгибающейся пружиной (Buckling Springs): Разделите слои мембран и протрите каждую со всех сторон мягкой тканью (можно с дистиллированной водой), и высушите сухой тканью. Если слои мембран склеены между собой — опустите всю мембрану в дистиллированную воду и поболтайте ей. Вы можете использовать ткань или бумажные полотенца, что бы удалить всю воду между мембранами. Резиновые полусферы можно мыть только при комнатной температуре, слишком горячая или холодная вода может изменить ощущение от нажима на клавиши. Пружинки, молоточки, металлическое основание клавиатуры могут потребовать более тщательной отмывки, но вы всегда можете использовать мыло или спирт.
  • Keyboards with rubber hemispheres on top of the circuit board, and Topre buttons: Only wash the gum in distilled water at room temperature, the Topre board and springs can be washed in water with a small amount of soap or alcohol. Then wipe the circuit board with a cloth dampened in distilled water.

5. Whatever keyboard you have, you need to dry it well. Lay out all the components separately and let them dry for at least half a day. If there are printed circuit boards with electronic components, it is advisable to blow thoroughly with a hairdryer to remove all moisture from under them.
6. When you are completely sure that all parts are completely dry - assemble the keyboard.

Update: Questions from comments:

Layout


As far as I understand, there are 4 main keyboard layouts:
* US / American - Enter on one line


* UK / British - Enter wide on the top in two lines


As well as two layouts with Enter in two lines, wide at the bottom. In doing so, backslash (\) shortens shift or backspace.

Cyrillization


Drawing the Russian alphabet is done on almost any keyboard using laser engraving, it’s inexpensive, it’s not difficult to find an office that can do this.

From translator


Interest is not idle at all, I have been looking for a good and reliable keyboard for a long time.
Desires were also added by the IBM keyboard, which was available at hand until recently, of the ~ 1985 model, which had not been disassembled for more than twenty years, its performance, indestructibility, and work sensations were excellent. Frustrated only by a loud click (not an amateur) and the lack of win-keys.
So some time ago, the options were studied and keyboards were bought that now enjoy working every day:

Ducky DK9008 Shining and Das Keyboard S Professional Silent


Both on Cherry MX Brown (cost about 6-7 tyr per piece).
You can set your own questions.

PS Only I wanted to write that in Russia you will not find such keyboards (with the exception of the "gaming" keyboards on Cherry Black, which do not give such pleasure from typing), as I accidentally stumbled into the keyboardshop.ru store online . Prices do not look small, but if you yourself are not abroad, then the difference in the real purchase price abroad will most likely be small.

PS Russian Wikipedia still does not contain an article about what types of keyboards are, and how they differ from each other. I think a noticeable omission. (And in the Russian Wikipedia there is a page only about membrane keyboards, while only thin keyboardless keyboards are described there).

PS Some stores incorrectly indicate the type of keyboard is “mechanical”, for example, when searching on the yandex market. The main distinguishing feature will be the price - a mechanical keyboard cannot cost cheaper ~ $ 100 (in Russia - more), the keyboard should clearly indicate which buttons are used in the keys. For example, many "gaming" keyboards, despite the prohibitive price tag of $ 200-500, are not mechanical.
