Mechanical Switches

How to Choose

When It Matters

Modern keyboards are filled with extra features, such as macro-programmable keys, RGB lighting, and USB passthroughs. However, one thing that hasn't changed much over the years, and remains an integral part of the user experience, are the mechanical switches used. Mechanical switches are an evolution from the buckling spring mechanism used in the IBM Model M in the 1980s and 1990s. Each mechanical switch has a plastic housing, a stem that holds the keycaps, and a spring, which is one of the more important parts because it gives the key a certain feel. When you press down on the key, it activates a physical switch in the housing, which then sends a signal to the keyboard to say a specific key was pressed. With the help of the spring, the key then comes back upwards to rest in its natural position.

There are three main types of switches: tactile, clicky, and linear. Most big companies label them as brown (tactile), blue (clicky), and red (linear), but it varies between each brand. Each provides a unique feel and provide their own sound feedback. Each switch type has its own unique pre-travel and total travel distance, as well as actuation force. The pre-travel distance is the distance it takes to travel when you press it down before it actuates, and the total travel is how far it can go before it bottoms out. Most people will care more about pre-travel distance because most switches have roughly the same total travel distance. A lower pre-travel distance is generally better for gaming because it allows for quicker actuation, while a higher pre-travel is usually better for typing because it helps decrease the number of typos.

However, this comes down to personal taste and whether you like a lower pre-travel or not. Also, the actuation force is the amount of force it takes to actuate the key. Tactile and clicky switches have higher actuation than linear switches because there's a 'bump' before actuating the key. It kind of feels like the key is resisting before you press it all the way down. This helps avoid typos, and it's known as tactile feedback. Some switches are also labeled as 'RGB', but that doesn't affect their performance, as it just allows the RGB lighting to pass through the switch.

Tactile

Tactile switches are likely the most popular switch type on the market. They're known to have a good balance between typing and gaming because they offer good tactile feedback and, depending on the brand, aren't very heavy to press. This is ideal for typing, as you'll know when you're about to register a keypress, and it helps reduce typos. If you're looking for your first mechanical keyboard, they're a good place to start. They're also quiet compared to other switch types, but it may produce a lot of noise if you tend to bottom-out the keys.

We listed some of the most popular tactile switches. We're providing the advertised measurements because we haven't tested all of them, and even for the switches we've tested, results vary due to manufacturing tolerances. You can see which keyboards we've tested from each switch with the links below. We've also individually tested some switches from our switch test kit, that we haven't tested with individual keyboards. You can see the actuation graph by clicking on the thumbnails.

Note that there are many other kinds of tactile switches, such as Outemu Brown, Greetch Brown, KBT Brown, MOD M Tactile, MOD SH Tactile, Black Alps, and Topre, amongst many others. Also, we measure the actuation force in gram force (gf), while some companies advertise it in centinewton (cN). We use the measurement that each brand advertises, but the two units are identical.

Clicky

Clicky switches are extremely similar to tactile switches. They provide the same tactile feedback, making them very popular for typing, and they produce an audible click. This could be particularly problematic if you work in an open-office environment, as the loud noise may bother people around you. You can listen to an example of the noise that clicky switches make here.

Below are the most popular clicky switches available with their advertised measurements, and we've provided tables to show the individual results of the keyboards we tested, as well as some individual switches we've tested. This is a small list of the countless clicky switches available, so if we've missed any popular ones, let us know.

Linear

Linear switches are entirely different from tactile and clicky switches. These are considered great for gaming because they're light to press, and they don't offer any tactile feedback, but again, this comes down to personal preference. There's no bump before the actuation point. The main downside to linear switches is that if you're going to use them for typing, they're so sensitive, and you might not know when you've actuated a key, but there are some linear types with high actuation, so they're not as sensitive. Linear switches are also quiet, so they won't bother people around you.

Below are the most popular linear switches with their advertised measurements. Our results may vary from the listed measurements due to manufacturing tolerances. There are many types of linear switches that we haven't listed, such as Greetech Red, Greetech Black, Hall Effect Linear, and Outemu Black, among many others. Let us know if we've missed any other popular brands.

Other Types

Manufacturers have pushed the pace of innovation and have come out with different types of switches over the years, besides the traditional ones. These new switches are still considered mechanical but behave differently from the linear, tactile, and clicky switches listed above. They each present their unique characteristics and typing experience.

Optical

Optical switches are starting to become more popular, and they're usually found on higher-end keyboards. They're similar to typical mechanical switches in that they use a spring to provide some resistance and recoil upwards once it's actuated. However, an optical switch doesn't trigger any physical switch, but rather, an infrared light detects when the key is pressed. This helps make the keys feel more responsive, which is great for gaming. Most of them have a linear feel, although there are some with tactile feedback. Also, some optical switches have customizable pre-travel distance, such as SteelSeries's OmniPoint of Flaretech's optical switches.

Listed below are a few optical switches. We haven't listed them all, so let us know if we've missed any.

Low Profile

Low profile switches use the same mechanism as standard mechanical switches, but as the name suggests, they're shorter and have a lower profile. This means that the total travel distance is much lower than standard switches, so they bottom out quicker. However, not everyone likes the feel of low profile switches, and choosing a low profile over a standard really comes down to personal preference. Low profile switches can have a linear, tactile, or clicky feel, and we listed a few examples below.

Hybrid Mechanical

Only a few manufacturers have dived into the world of hybrid mechanical switches. Many non-mechanical keyboards have rubber dome switches, which feature a membrane underneath the key that, when pressed, closes an electric circuit and lets the computer know that the key has been actuated. Unlike mechanical switches, a hybrid switch doesn't have a spring. SteelSeries created a hybrid switch that uses a spring, like in a mechanical switch, and included a membrane at the bottom that closes the electric circuit to send signals to the computer. It doesn't use a physical switch like standard mechanical switches. You can read more about it in the SteelSeries Apex 5 Hybrid Mechanical Gaming Keyboard review.

Our Tests

The ways we measure a switch's characteristics are very simple. We use one test, called the keystroke test, to measure the pre-travel distance, total travel distance, and actuation force. We use a Mecmesin MultiTest-i System Test Stand and place it on an alphanumeric key to measure these aspects. We normally measure just one key, but since each switch may be slightly different due to manufacturing tolerances, we may measure a second key to confirm test results if our data looks off. One limitation to our testing is that we measure the actuation force at the actuation point, and we don't calculate the actuation force needed to get over a tactile bump. However, you can still look at the graph to see the highest actuation force needed to actuate the key.

We also test for typing quality, which takes into account the keycap shape, spacing, quality, and ergonomics, so the switch type isn't the only deciding factor with the typing experience, but obviously, it impacts the typing experience. This is a subjective test, and you might not like typing on a certain keyboard while others do. We also measure the typing noise, and usually, clicky switches are the loudest, while linear switches are the quietest.

Conclusion

Entering the world of mechanical switches can seem daunting at first, and there are many different switches you can choose from. Each manufacturer creates their unique characteristics in a switch, and although a Gateron Brown and a Cherry MX Brown are both tactile switches, they perform and feel a bit different from each other. It's easy to get caught up in the details before buying a mechanical keyboard, but you won't know for sure how you like a certain type of switch until you try it yourself. Some switches are designed for gaming, while others are designed for office use, so it's important to know what you're going to use your keyboard for ahead of time. Overall, switches may be small, but they have a huge impact on the user, and you can eventually find the ones that suit your needs.
