The Secret of Mechanical Keyboard Switches

What Are Keyboard Switches?

Mechanical Keyboard Switches, known asKeyboard Switches, are the mechanisms under the keycaps on a mechanical keyboard. They register every single press of a key. The variety of auditory feedback, tactile feedback, and force to activate the switch define your typing experience.

TheComponents of Keyboard Switches

Mechanical keyboard switches consist of metal contacts, the structure of different components directly affects the auditoryfeedback of themechanical keyboard, let’s take a look at the below illustration.

A. Upper Housing - Keycap stabilizer with buckle, it is designed to protect the movement of the mechanical switch and belongs to the packaging mechanism.

B. Stem - The part underneaths the keycap that moves down when pressed, creating key travel feel and determines the switch type. The clicky switchis a sub-settypeofswitchthat focuses on producing a tactile bump and loud audible click with each keypress.

C. The Crosspoint Metal Contact -The Stem has two metal contacts composed of a dynamic and a static plate. Once you press a key, the contact mechanism hits the PCB and closes the switch circuit, thusrendering a keypress.

D. Spring -The resistance of the coil spring determines the amount of force needed to actuate the key. It also guides the switch to slide back to its original position. Material, number of coils, and coil diameter affect the restoring force; stainless steel wire, carbon steel, piano wire are common materials for mechanical springs.

E. The Base Housing -This bottom housing component is the final part of the key switch anatomy. The base housing is where the actual installation of the switch to the keyboard, is mounted to the PCB.

Types Of Keyboard Switches: Linear, Tactile, and Clicky

Before dividing into the types of mechanical switches, let’s take a look at the characteristics of the mechanical switches.

Click Sound

The sound and principle are different when pressing the key, and the difference in the installation medium will also generate different sounds. By pressing down a switch, a clicky switch generates vibration and creates a sound by squeezing the upper housing of the mechanical switch, while the base housing hits the positioning board or PCB board.

Typing Feel

Bump feedback: A pause and snap-in as the key is pressed down.
Straight and smooth: A smooth feeling when pressing the switch from top to bottom.

Based on the sound and feedback given by tapping the mechanical switch, they can be divided into three categories, linear, tactile, and clicky.
Linear-The keystroke is consistent and smooth.
Tactile-A bump in the middle of travel, usually around the actuation point.
Clicky-A bump in the middle of travel accompanied by a sharp “click” sound.

Linear Switches: Smooth as Butter

1. What Are Linear Switches?

The linear switch is the simplest. It is a switch that focuses on generating a smooth, continuousactuationwithout any feedback or noise.The key travel is a straight downward drop with no tactile bump or clicks leaf from the moment you start pressing the key, thereby, a key is easily bottomed out . The linear switch is very suitable for those who like quiet and smooth typing.

2. Should You Get Linear Switches?

Linear switches are both smooth and easy to use, they are very popular in the gaming community, especially the linear speed switch. People who are used to using membrane keyboards may bottom out the switches too often which can cause mild finger pain and discomfort. Therefore, those new to the mechanical keyboard are not recommended to choose linear switches. However, once you get used to linear switches, you will find them very pleasant and fall in love with them!

Tactile Switches: Bumpy and Satisfying

1. What Are Tactile Switches?

Tactile switches have a small tactile bump that provide resistance and produce a relatively quiet audible click. Based on the feedback as you type, you can tell by the sound and feel at the point of key actuation. Not to mention that they are satisfying and fun to type on.

2. Should You Get Tactile Switches?

Tactile switches are fun to use and offer you good feedback when typing, allowing you to enjoy asatisfying bump with everykey travel. Tactile switch produces bump of varying sizes when key travel is registered (depending on the switch type), and it produces a small clicking sound. It is not as loud as a clicky switch and using it in public will not attract too much attention. For beginners or anyone new to mechanical keyboards, the tactile switch is a good choice and will be a nice upgrade from your membrane keyboard.

Clicky Switches: Loud and Bumpy

1. What Are Clicky Switches?

The clicky switch produces a tactile bump and a loud clicking sound every time key travel is registered.When typing, you don’t have to bottom out the keys, it provides good feedback, and you get a slight indication of a keypress so you know that everything is working properly.You can release the key immediately after receiving the feedback.

2. Should You GetClicky Switches?

Clicky Switch is fun to use and can provide the best feedback of all the switch types, but before buying akeyboardwith aclickyswitch, you should consider its sound. Although you may like the click sound, using a mechanical keyboard with clicky switches at the office or in a library may not be a good idea, as they are loud and may irritate those around you. Of course, if you are working in a private space or have a dedicated space that does not need to be very close to others, just choose your favorite two-segment keyboard.

Parameters of theKeyboard Switches

The various parameters of the mechanical switches determine their performance and feel when you type on them.

• Total travel distance:represents the maximum distance the actuating element can travel during its operational cycle.
• Pretravel:represents the distance or angle through which the actuator on the limit switch must travel before it trips the switch contacts.
• Initial force:represents the magnitude of the force that is needed to produce actuator movement.
• Actuation force:represents the force received when the switch is triggered.
• Tactile force:represents the force that a mechanical switch receives when passing through the operating point.
• Bottom-out force:represents the force when the mechanical switch bottom out.
• Actuation point:represents the force needed to actuate the key to thekeyboard. It’s also called operating position.
• Tactile point:represents where you can feel in the keypress before bottoming out. On linear switches, there is no tactile position.
• Reset point:represents thepointat which the switch stopsregisteringakeypress.

According to the trajectory curve of different switches when bottoming out, the characteristics of different switches are more intuitive than parameters. Take a look at the following example of Cherry MX switches.

The red line in the figure is the trajectory of clicking the switch, and the black line is the switch rebound.

(Image Graph of Cherry MX Red switch)

• Theinitial force is 30cN, that is, the force greater than 30cN can drive the mechanical switches to move.
• When the force gradually reaches 45cN, the actuation point is reached. At this time, the travel is 2mm, the switch is closed, and an effective signal is generated, that is, the word has been typed.
• When you release the key, it resets at 1.9mm, you can press it again at this time.When the actuation point is very close to the reset point, it is very helpful for double-tap or triple-tap, especially in games.
• When your force reaches 65cN, the total travel of the mechanical switch is 4mm, that is, the mechanical switch has bottomed out. At this time, your finger and the spring's resilience will gradually decrease, and the travel will gradually return to the original point from 4mm.

(Image Graph of Cherry MX Blue switch)

• Theactuation point at 2.2mm, the reset point is at 1.6mm, and the button can be triggered with only 45cN of force.
• When the force reaches 65cN and the operating point is reached, the switch will give you tactile feedback.At this time, the button has reached the bottom of its 4mm travel.

Switch Color Options

There are a lot of options when it comes to tactile feedback and audible click. Mechanical keyboards are generally classified according to their switches, and switches are classified by color which embodies different design principles. Black, Red, Brown, and Blue switches feature different audible clicks and a tactile bump.

Blue Switches –Clickywith a Medium Bump

Blue switch has the most noticeable mechanical feel, with clicky sound and the distinct sense of operating, it’s ideal for gaming or typing, delivers a very comfortable feeling and a sense of rhythm.However, people may find Blue switch has an inputlatency issue if they prefer a highly responsive switch, so the Blue switch may not be the best option for high-speed typing and long hours typing.

Brown Switches –Tactile with a Medium Bump

It is a relatively modest switch and barely tactile, its sound is not as crisp as the Blue switch. The blue switch also has the lightness of the Red switch, a tactile feel that is close to a membrane keyboard. Brown switch is ideal for those who are new to a mechanical keyboard.

Red Switches - Linear Without Bump

Red switch requires less force to actuate and light. It is very popular when typing. It will feel like flying between your fingers. It is very suitable for long-time typing and high-speed input. At the same time, the red switch triggers fast and can also take care of it well. To the game, the red switch is also very suitable for novices to buy.

Green Switches -Clicky, Stiffer

Similar to the Blue switch, but the spring is stronger which makes it rebounds higher and more powerful.In other words, the Green switch is designed for gaming.

Black Switches - Linear, Stiffer

It is a kind of power mechanical switch, it neither tactile nor clicky. The black switch can come across as stiff. This type is thus less suitable for the kind of nimble key work most speed and touch typists depend on, it is not recommended for novices to try the black switch.

Silver Switches – Linear, Lighter

It is called the switch of speed, you can trigger it by just pressing it down a distance of 1.2mm. As a result, the delay between pressing down a key and performing an action is kept to a minimum, making Speed Silvers a refreshed favorite for gamers. However, because it is too sensitive, it’s easy to accidentally touch more than one key when typing or playing games.

Switches Comparison Guide

The following is a list of the most popular mechanical switches and their distinct features.
They are classified by linear, tactile, and clicky types, you can sort the features according to preferences, yourself, which will help you determine the most suitable switch for your needs.

Hot Swappable Keyboard and Soldered Switch

The user-friendliness of the hot-swappable socket has become a popular choice for mechanical keyboard users, this is because:

• It’s easier to remove and replace the switches.
• With higher flexibility and an ability to upgrade the switch.
• Able to integrate compatible switches to create a customized typing experience.

What Are the Differences Between 3-Pin and 5-Pin Cherry MX?

People frequently discuss 3-pin and 5-pin switches, so what are the differences between them? At present, most switches on the market are made based on the structure of MX Switches. The differences between 3-pin and 5-pin switches are the composition, pressing feel, and the way how they're mounted.

1. Different Composition

A: 3-pin switches have two metal pins that allow the switch to work, and a middle plastic “pin” that looks more like a large cylindrical knob.
B: 5-pin switches are designed based on 3-pin switches, and there are two extra plastic pins or better stability.

2. DifferentMounting Sytles

5-pin switches can be soldered and mounted directly to the PCB with nothing in between, making for a relatively simple installation.The PCB mounting style is generally used with smaller keyboards.

Since the 3-pin switches lack the two extra plastic stabilization pins, they usually require a metal plate for better reinforcement and stability. The 3-pin switches are soldered to the PCB after being placed in the metal plate.This mounting tactic is mostly intended for larger keyboards. However,switches on a hot-swap board can be easily installed into the plate instead of soldered to the PCB.

3. 3-pin switches or 5-pin switches? Which one should I buy?

First, you need to figure out whether your PCB supports 5-pin switches. You need to check if there are 2 fixed plastic pins on your PCB, if so, it will be compatible with 5-pin switches; otherwise, 3-pin switches probably serve you better. In case you’ve already purchased 5-pin switches before checking the PCB mount compatibility, you'll need to clip the extratwoplasticpinsoff to make them fit.

How to Choose the Right Switch?

If you want to choose a suitable mechanical switch, below are the top 4 key factors you should consider.

1. Environment

The first thing you should consider is the environment in which you are using the keyboard.Where will you use the keyboard?Is it used in someone’s office or a private space?

Some people like to hear a click when typing because it can indicate that a key has been pressed.Even theclickyswitch is nostalgic, just like an old typewriter. But typing on a mechanical keyboard generates a high-pitched and loud “click” sound, and it may irritate those around you. So when you decide on your switch, look at your surroundings and consider the people around you, and make sure you won’t disturb others .

2. Tactile Preference

The second factor you should consider is the typing feel.Do you prefer a slight bump in every keypress or a smooth one? When typing, thetactile feedback from tactile and clicky switches offers more accuracy. As you can easily tell whether a keypress has been registered without needing to bottom out your keys. Once you feel the bump, you can quickly move on to the next key, therefore tactileswitches are more suitable for typing. Linear switches are stable and smooth, with higher consistency, they are ideal for gamers who pursue a speed in the game.

3. Your Hand Size, Strength, and Typing Style

There are other factors that are worth considering when choosing a mechanical switch, for instance, your hand size, strength and typing style.

People withbighands tendto possessmisclicks compared tothose whohave small hands. Ifthis is your case, thenit mightbe ideal for you to use switches with:

4. The Purpose of Using a Mechanical Keyboard

To choose a switch that suits you the best, you should also consider the purpose of using a mechanical keyboard. Are you going to use it for gaming? Typing? Or both?

• Ifyou want to experience the charm of mechanical keyboards, we recommend you to choose Blue switch.
• If you are going to use the keyboard for gaming, such aslol ordota, the Black switch is what you are looking for.
• If you are going to use it for gaming such as2K, dnf, fpsgames (direction keys), and you are a hardcore player, the red switch or brown switch will serve you the best.
• If you are a programmer or die hard typist, you may consider choosing Blue switch＞Brownswitch ≈ Redswitch.
• If you are going to use the mechanical keyboard in the office, Red switch is recommended.

Mechanical Keyboard Switches Brand

Below are some popular mechanical switches brands on the market, let’s take a look.

Cherry MX

A German manufacturer of computer accessories. The company was founded in the United States and moved to Germany in the 1970s. The company is currently known for producing high-quality mechanical keyboards and mechanical switches. The Cherry MX switch designed by the company was developed and patented in the early 1980s and has been used worldwide since 1983. It is currently the most popular mechanical keyboard switch.

Terminology

● O-Ring- is a small O-shaped rubber-rings, that are put on the stems of your keycaps. They change the feel of each keypress, depending on their size and hardness. It can reduce shortening the travel distance of the key until the bottom-out-point, changing how a full keypress feels and also how the keyboard sounds.
● Linear- is a type of mechanical switch that focuses on producing a smooth, consistent actuation without any tactile feedback.
● Clicky- is a type of mechanical switch that features a distinct click sound that can be heard when the switch is fully actuated.
● Bottoming Out- Bottoming out is when you press a key all the way down until the keycap hits the upper housing of the switch
● Key Bounce- often appears in contact switches. When the contacts collide, the conductive metal plate will vibrate and bounce, resulting in jerky signal jitter. Normally, the scan rate is limited by the bounce time of the key switches used and the debounce algorithm used. For example, the debounce time of a mechanical switch is rated at ≤5ms to prevent misclick.
● Key Lifecycle- The lifespan of a key switch, or how many times a key switch can be activated before failing. Usually represented by 20 - 80 million keystrokes for mechanical keyboards, but some can reach 100M times.
● Double Tap– Double-tap the key in rapid succession. There will also be three combos, which are common in-game operations.
● ALPS- An ALPS mechanical switch produced by Alps Electric from the 1980s to the early 1990s and has now been discontinued. The current ALPS mechanical switches are all cloned and produced by Matias.
