Optical vs Mechanical Switches: What’s Better Switch?

Optical switches use infrared light to detect when you’ve pressed a key to register a keypress. Mechanical switches use physical contact to register a press. Optical switches are generally faster to actuate than mechanical switches and have a longer lifespan. Though some mechanical switch brands match this performance criterion. Mechanical switches can be more satisfying and quieter, especially linear keys.

Let’s dive deep to explore every criterion in detail to know the differences!

Optical vs Mechanical Switches

Criteria	Optical Switches	Mechanical Switches
Switch mechanism	Uses a light beam to register keystrokes, no physical contact points that can wear down over time	Physical contact points between metal parts to register keystrokes, which can wear down with use
Durability	Highly durable due to lack of physical contact points, resistant to dust and debris	Known for durability and longevity, designed to withstand millions of keystrokes without wearing out
Actuation force	Generally lighter and easier to press, faster actuation speed	Typically requires more force to actuate, slower actuation speed
Sound	Quieter and less audible, less tactile feedback	Audible clicks or bumps when keys are pressed, more tactile feedback
Customizability	Limited options for customization, less moddable	A wide range of customization options is available, highly moddable

How do Optical And Mechanical Switches Work?

Both optical and mechanical switches have a central key stem inside a plastic housing that moves up and down when pressed. However, the way they detect the keypress is different.

Optical switches use a light beam to detect the key press. When the key is pressed, it interrupts the light beam, and the sensor detects the change in light. The sensor then sends a signal to the computer, which registers the keypress. The entire process is contactless, which means there is no physical contact between the key and the sensor. This design makes optical switches more durable and less prone to wear and tear.

On the other hand, mechanical switches use a physical switch to detect the key press. When the key is pressed, the switch is activated, and it sends a signal to the computer, which registers the keypress. The switch is made up of several components, including a stem, a spring, and a metal contact. When the stem is pressed down, it compresses the spring and makes contact with the metal contact, closing the circuit and sending the signal to the computer.

One of the key differences between optical and mechanical switches is the actuation point. The actuation point is the point at which the switch registers the keypress. Optical switches have a lower actuation point than mechanical switches, which means they register the keypress faster. This can be an advantage for gamers or anyone who needs to type quickly.

Switch Feel

The feel of a keyboard switch refers to the tactile and auditory feedback it provides when a key is pressed. Mechanical switches are known for their tactile feedback, which provides a satisfying “click” or “bump” sensation when the key is pressed. (To know more about the different mechanical switches comparison, like tactile vs clicky vs linear, you can check this post written by me.)

Optical switches, on the other hand, do not provide as much tactile feedback and are often described as “mushy” or “linear”. However, some prefer the smoother feel of optical switches for typing or gaming.

Durability

In terms of durability, optical switches are generally more durable than mechanical switches, with a lifespan of up to 100 million clicks, which is about double the usual lifespan of mechanical switches which is around 50 Million Clicks.

Mechanical switches are known for their durability and longevity, as they are designed to withstand millions of keystrokes without wearing them out. Optical switches are also durable, as they do not have any physical contact points that can wear out over time.

However, both switches can be prone to malfunction if they are exposed to dust or debris, so it is important to keep your keyboard clean and free from contaminants.

Actuation Speed

When it comes to actuation speed, optical switches have the advantage over mechanical switches. Since optical switches do not rely on physical contact points, they can register keystrokes faster and more consistently than mechanical switches.

This means that you can execute commands more quickly and with greater precision, which can be especially beneficial in fast-paced games where split-second decisions can make all the difference.

On the other hand, mechanical switches are still relatively fast and are more than adequate for most gamers. While they may not be as lightning-fast as optical switches, they can still provide a satisfying and accurate gaming experience.

Additionally, some gamers may prefer the tactile feedback and satisfying “click” sound that mechanical switches provide.

It’s worth noting that actuation speed is not the only factor to consider when choosing between optical and mechanical switches. Other factors, such as durability, customization options, and overall feel, should also be taken into account

Price Point

When it comes to choosing between optical and mechanical switches, one of the most important factors to consider is the price point. Here are a few things to keep in mind:

• Optical switches are generally more expensive than mechanical switches, making them less accessible for people on a tight budget.
• However, it’s important to note that the price difference between the two types of switches can vary depending on the brand and model. Some mechanical switches can be just as expensive as optical switches, while some optical switches can be relatively affordable.

If you’re on a tight budget, it’s worth considering mechanical switches. They tend to be more widely available and come in a range of price points, making them a good option for those who want a quality keyboard without breaking the bank.

On the other hand, if you’re willing to spend a bit more money, optical switches can offer some advantages over mechanical switches. For example, they tend to have a longer lifespan and require less maintenance, which can save you money in the long run.

Sound of Clicks

One of the most noticeable differences between optical and mechanical switches is the sound they produce when typing. Mechanical switches have a distinct “click” or “clack” sound that some people find satisfying, while others find it distracting. The sound comes from the switch mechanism and is produced when the switch is activated.

It’s worth noting that not all mechanical switches produce the same sound. There are different types of mechanical switches, each with its own sound profile. Some switches are designed to be quieter than others, while others are designed to be more tactile or clicky.

There are other mechanical switch options that are absolutely silent too, like the linear switches.

Optical switches, on the other hand, are generally quieter than clicky mechanical switches. However, they still make hollow sounds and are not as quiet as the linear ones from mechanical switches.

So, you need to fix your noise preference while choosing these switches as click noise is very subjective and the preference varies from person to person.

Modding Ability

When it comes to modding, mechanical switches have the upper hand. This is because mechanical switches have been around for much longer than optical switches, and as a result, there are more options available for customization. Here are some ways you can mod your mechanical switches:

• Switches: You can swap out the switches on your mechanical keyboard to change the feel and sound of your typing experience. There are many different types of switches available, including linear, tactile, and clicky switches.
• Keycaps: You can also change the keycaps on your mechanical keyboard to give it a different look and feel. There are many different materials and designs available, from ABS plastic to PBT plastic to metal.
• Stabilizers: Stabilizers are used to keep larger keys, such as the spacebar and shift keys, stable when pressed. You can swap out the stabilizers on your mechanical keyboard to improve the feel of these keys.

On the other hand, optical switches are more difficult to mod. This is because the technology is still relatively new, and there are fewer options available for customization. However, some optical switches do come with hot-swappable sockets, which allow you to swap out the switches without soldering.

So, if you’re someone who likes to customize your keyboard, mechanical switches are the way to go. There are simply more options available for customization, and the technology has been around for longer. However, if you’re not interested in modding your keyboard, optical switches may be a better option for you, as they are generally more durable and have a smoother feel.

Availability

Both optical and mechanical switches are widely available in the market, with numerous brands and models. Some popular optical switch brands include Gateron, Kailh, and Flaretech, while popular mechanical switch brands include Cherry MX, Gateron, and Kailh. Availability may depend on your location and specific preferences.

It is important to note that some keyboard manufacturers may only use one type of switch in their products, so it is important to research and choose a keyboard that uses the type of switch that best suits your needs.

Additionally, it is worth considering the availability of replacement switches if you plan on customizing or repairing your keyboard.

Mechanical switches are more widely used and have been around for longer, so replacement switches are generally more widely available.

However, as optical switches become more popular, replacement switches may become more readily available as well.
