Understanding Mechanical Keyboard Switch Basics

Mechanical keyboard switches are the individual mechanisms beneath each key that register when you press down. Unlike rubber dome keyboards found on most laptops and budget keyboards, mechanical switches use a spring and stem design that provides tactile feedback with each keystroke. This information guide explores how these switches work and what makes them different from other keyboard types.

Each mechanical switch contains several key components. A spring sits beneath a stem (the moving part), and when you press the key, the stem travels downward, compressing the spring. At a certain point during this travel, the switch registers an electrical signal to your computer. The housing, typically made of plastic, holds all these parts together. The total distance the stem travels is called travel distance, which commonly ranges from 1.5mm to 4mm depending on the switch type.

The actuation point is the depth at which a switch registers your keystroke. Most mechanical switches actuate between 1.5mm and 2.2mm of travel, meaning your computer receives the signal before you've fully pressed the key down. This is different from rubber dome keyboards, which require you to press all the way down to register input. The actuation force refers to how much pressure (measured in grams) you need to apply to trigger the switch. Typical actuation forces range from 35 grams to 80 grams.

Understanding these basics matters because different switch types vary significantly in how they feel and sound. A switch designed for typing may feel entirely different from one designed for gaming. Some switches provide audible clicks with each press, while others operate silently. Learning about these differences helps you understand what to look for when exploring switch options.

Practical Takeaway: Mechanical switches use spring-loaded stems to register keystrokes, with variations in travel distance, actuation point, and actuation force creating different typing experiences. Knowing these terms helps you compare different switches and find one suited to your needs.

Exploring Linear Switch Characteristics

Linear switches represent one of the three main categories of mechanical switches. These switches provide a smooth keystroke from top to bottom with no tactile bump or audible click. When you press a linear switch, you experience consistent resistance throughout the entire downstroke, then the spring pushes back as you release.

The name "linear" comes from the consistent resistance graph—if you were to chart the pressure needed to move the stem down, it would look like a straight line rather than showing peaks or valleys. This consistent feeling means you get predictable feedback with every keystroke. Linear switches are popular among gamers because they allow for rapid key presses without the interruption of tactile bumps or clicks.

Common linear switch examples include Cherry MX Red (45g actuation), Gateron Yellow (50g actuation), and Kailh Box Black (60g actuation). The numbers indicate actuation force in grams. A lighter switch like the Red requires less finger pressure and may feel faster, while a heavier switch like the Black provides more resistance and can prevent accidental presses. Many typists find linear switches fatiguing for extended writing sessions because they provide little feedback about whether a key registered without hearing or feeling confirmation.

Linear switches come in different stem colors, and the color typically indicates the actuation force and manufacturer. Red stems usually mean lighter actuation (around 45g), while black or dark stems often indicate heavier switches (60g or more). Some manufacturers produce linear switches with different tactile preferences—some feel very smooth due to specially designed stem shapes, while others might have slight variations in smoothness.

Linear switches are typically quieter than other switch types, though this depends on the housing material and manufacturing quality. Budget linear switches might produce a hollow sound, while premium linear switches sound deeper and more satisfying. The keyboard case and stabilizers (the components supporting larger keys like spacebar and shift) also affect the overall sound.

Practical Takeaway: Linear switches provide smooth, consistent keystroke feedback without bumps or clicks, making them popular for gaming and rapid typing but offering less tactile confirmation for writing tasks.

Learning About Tactile Switch Options

Tactile switches provide a noticeable bump in the middle of the keystroke that you can feel through your finger. This bump occurs before the actuation point, giving you physical feedback that the switch is responding to your press. Unlike linear switches, tactile switches create a distinct sensation that many describe as satisfying and informative during typing.

The bump in a tactile switch comes from a different stem design or internal mechanism that creates resistance at a specific point in the travel distance. When your finger hits this bump, you feel a clear change in resistance. After passing the bump, the resistance typically decreases toward the bottom of the keystroke. This design helps typists confirm that their keystroke registered without needing to hear a sound or press all the way down.

Popular tactile switches include Cherry MX Brown (55g actuation), Zealios (62g actuation), and Outemu Brown (55g actuation). The Brown switches are considered a moderate option with a subtle bump, while Zealios switches provide a more pronounced bump that many typists find highly satisfying. Actuation forces for tactile switches typically range from 45 grams to 70 grams depending on the specific model.

Tactile switches vary in bump shape and intensity. Some have a smooth, rounded bump that feels gentle, while others have a sharp, pronounced bump that creates a more obvious sensation. A "sharp" bump gives faster feedback and a more dramatic sensation, while a "smooth" bump feels gradual and subtle. Personal preference determines which bump type feels better—there's no objectively better option, only what feels comfortable to individual users.

One consideration with tactile switches is that the bump creates more friction than linear switches, which may slightly reduce typing speed for users transitioning from linear designs. However, many typists report increased accuracy with tactile switches because they confirm keystroke registration mid-press rather than requiring a complete downstroke. Tactile switches also tend to produce moderate noise levels—louder than linear switches but quieter than clicky switches.

Practical Takeaway: Tactile switches produce a physical bump mid-keystroke that provides confirmation your key press registered, making them preferred by many typists despite requiring more effort than linear switches.

Comparing Clicky Switch Mechanisms

Clicky switches combine tactile bumps with audible clicks, providing both physical and audio feedback with every keystroke. The click sound comes from a mechanism inside the switch that generates a distinct "click" noise when the stem passes through the actuation point. This combination of feedback types makes clicky switches the most pronounced and perceptible of all mechanical switch types.

The clicking mechanism typically uses a small metal leaf or stem design that creates sound when struck. The most famous clicky switch is the Cherry MX Blue, which has been in use since the 1980s and remains a standard comparison point for other clicky switches. The Blue actuates at 50 grams and produces a distinctive sound that many people recognize instantly. Other clicky options include Kailh Box White (50g actuation) and Outemu Blue (50g actuation).

Clicky switches produce sound levels typically ranging from 60 to 70 decibels depending on the switch model and keyboard construction. For reference, normal conversation occurs around 60 decibels, so clicky switches can be quite loud. This loudness makes them popular among some typists who enjoy auditory feedback but less suitable for shared workspaces or quiet environments. The sound is one of the most divisive aspects of mechanical keyboards—some people find it satisfying and energizing, while others find it annoying.

Beyond Cherry MX Blue and Kailh Box White, other clicky switches exist with different sound characteristics. Some produce sharp, crisp clicks while others produce deeper, mellow clicks. A few manufacturers create "mid-height" clicky switches that produce the click at a lower point in the travel distance than traditional clicky designs, which some users find more comfortable. The stem color varies by manufacturer and doesn't necessarily indicate actuation force in clicky switches.

Clicky switches generally have higher actuation forces than linear or tactile switches, though exceptions exist. The audible feedback means some users feel less need for heavy actuation force since they receive clear audio confirmation. Typists often report that clicky switches feel very responsive and informative during extended writing sessions, though the noise can become fatiguing in loud environments or for people sensitive to repetitive sounds.
