The 3 Main Types of Mechanical Keyboard Switches Explained

Knowing about the different mechanical keyboard switch types will help you find typing nirvana when customizing your board

Mechanical keyboard switches are the heart and soul of your board; they're the mechanisms underneath your keycaps that determine how precise and responsive your keys are, as well as the sound and feel of your typing. However, deciding on the best switches for your board requires an understanding of the different mechanical keyboard switch types, their unique characteristics, and their pros and cons for different uses.

This article is designed to help you make an informed decision when customizing your keyboard, whether this is your first time tinkering or you're a mechanical keyboard enthusiast. We'll break down the most popular mechanical keyboard switch types, their characteristics and best uses, where to buy them, and whether there are any compatibility issues to consider.

What are mechanical keyboard switches?

Mechanical keyboard switches are a small piece of a keyboard that typically consists of an upper housing and a base housing, a stem to mount the keycap and travel with each press, and metal contacts to register a press when a connection is made. It's these components that decide things like pre-travel and total travel distance, operating force, tactile point, reset point, and more. In layman's terms, you can think of your mechanical keyboard's switches as the guts of the keys, and depending on what's under your keycaps, you'll experience different sounds, physical feedback, and actuation points where your keypresses are registered.

What most folks consider when deciding between the various types of keyboard switches are actuation sound and typing feel. These characteristics are crucial not only to your comfort and satisfaction with a mechanical keyboard, but also how quickly and accurately you’ll be able to type according to your personal preferences. Naturally, these distinctions are important to consider whether you're using your keyboard for work, gaming, or general use. If you’re looking for a mechanical keyboard switches chart to make the comparison easier, has an excellent one to get you started.

The three main types of mechanical keyboard switches

Along with its keycaps, a keyboard's mechanical switches are a key factor distinguishing it from the rubber dome keyboards commonly bundled with pre-built desktops or available as lower-priced accessories. That's why it's crucial to have at least a surface-level understanding of the three most common mechanical keyboard switch types: linear, tactile, and clicky. Most of the big keyboard switch manufacturers label them red (linear), blue (clicky), and brown (tactile), but that's by no means a uniformly accepted rule.

In terms of compatibility, most of what you’ll find on the market are "Mechanical X-Point," or MX-style, switches, introduced by German manufacturer Cherry in the 1980s. While Cherry itself sells complete keyboards, many more keyboard makers use Cherry switches or MX-inspired variations like the ones from Gateron and Kailh. The market also hosts a range of less common switch types that aren’t based on the MX style, so it’s always best to confirm your keyboard’s specs before making a purchase.

Linear mechanical keyboard switches

The linear mechanical switch is the most straightforward of the three types, providing a light, smooth, and consistent keystroke all the way through the actuation point. Unlike tactile and clicky types, linear switches don't elicit a bump or click before registering a press, which means the only thing you'll feel as you type are the keycaps against your fingers, the pressure of the springs, and the base of the keyboard if you bottom out presses. That's because the mechanism allows the switch's stem to travel uninhibited, whereas the other types of keyboard switches elicit a physical bump on the verge of actuation.

Because there's nothing in the way between the weight of your finger and the switch's actuation point, linear switches are typically the fastest to use. People using custom keyboards for competitive gaming often prefer linear switches for that reason, as the milliseconds in time you save registering a keypress can be significant in fast-paced games. Linear switches are also generally the quietest of the three main keyboard mechanical switches, which is a plus if you're sharing a space with someone and don't want the sound of your typing to bother them.

One of the downsides to linear switches is that, precisely because they're so sensitive, it's easier to slip and register an incorrect keypress. This can hinder your productivity when adjusting to a new keyboard. Also, some find it difficult not to bottom out linear switches, which could result in more finger fatigue and more wear and tear on the switch.

Clicky mechanical keyboard switches

Whereas linear keyboard switches are light, sensitive, and quiet, clicky keyboard switches are heavier to press, more deliberate, and noisy. A clicky switch's mechanism includes a tactile resistance that you must push past to register a keypress, and the feedback and signature loud click it produces lets you know it went through. This is helpful if you prioritize accuracy when typing. Another benefit to clicky switches is that it's easier to avoid bottoming out presses, which means less strain on your fingers and the mechanisms. Last but far from least is the sound itself. Many enthusiasts spend years searching for just the right kind of audio feedback from their keyboards, and if you want the biggest sound possible, look no further than a clicky switch.

On the other hand, clicky keys can be a nuisance to coworkers or roommates if they don’t enjoy the sound quite as much as you (or at least not while they’re trying to have a meeting or sleep in). It's best to consider your setting before opting for clicky keys. While they're an excellent choice for those who delight in noisy keys and who can tightly control their working or gaming space, the tactile resistance and clattering associated with these switches make them less suited for gaming and crowded environments.

Tactile mechanical keyboard switches

Often considered a middle ground among mechanical keyboard switch types, tactile switches produce a similar bump before actuation as clicky keys, but with a much more muted sound. Though usually not as quiet as linear keys, tactile switches are a go-to choice for enthusiasts who want feedback without the clicky orchestra.

Whereas linear and clicky switches are best suited for specific purposes, tactile switches are all-purpose performers, perfect for those who use their keyboards for work, play, and leisure. However, the tactile switch's adaptability means it may not be the best choice for any one function, lacking the speed required for competitive gaming and the auditory feedback beginner and professional typists might require from their keyboards.

Some other mechanical keyboard switch types

While the most common types of keyboard switches are explained above, they’re not all you need to know about. You’ll really want to pay attention to keyboard compatibility while perusing storefronts that trade in these types of switches, as these aren’t all guaranteed to be compatible with the typical MX-style board setup.

  • Low-profile: These specialized key switches use the same basic mechanisms as most on the market, but they’re designed with a lower profile to lower the total travel distance, bottom out faster, and support a more minimalist aesthetic.
  • Optical: In optical switches, the physical switch used to register a keypress is replaced by an infrared light that tells the computer when a key has been actuated.
  • Hybrid: A hybrid switch uses a membrane similar to a standard rubber dome keyboard that closes a circuit to provide actuation, but it incorporates elements of a mechanical switch to achieve feedback.
  • Electrostatic capacitive: These switches build on the hybrid concept to combine a precise actuation point coupled with a satisfying tactile bump. Topre is the most famous type of electrostatic capacitive switch, and Topre Type-S switches can even cut down on noise without diminishing the overall feel.

With this guide, you should have all of the information you need to kit out your mechanical keyboard with switches specifically designed to achieve the sound and feel you want. has a good range of MX-style switches available in linear, clicky, and tactile configurations. That said, if you want to see for yourself why Topre keys have remained a favorite among enthusiasts for decades, HHKB offers a range of keyboards with beautiful, minimalist designs and these versatile switches under their keycaps.
