What are Optical Switches and How do they Work?

Optical switches are keyboard switches that use light to register keystrokes. When a key is pressed, a beam of light is interrupted by a stem within the switch, which sends a signal to the computer to register the keystroke. 

Optical switches are known for their speed and reliability, as they do not have any physical contact points that can wear out over time. They are also resistant to dust and debris, which can accumulate in mechanical switches and cause them to malfunction.

What are Mechanical Switches and How do they Work?

Mechanical switches are a type of keyboard switch that use physical contact points to register keystrokes. 

When a key is pressed, a spring-loaded stem within the switch makes contact with a metal or plastic contact point, which sends a signal to the computer to register the keystroke. 

Mechanical switches are known for their tactile feedback and customizable feel, as well as their durability and longevity.

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

Mechanical switches are known for their durability and longevity, as they are designed to withstand millions of keystrokes without wearing 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

Optical switches are known for their fast actuation speed, as they do not have any physical contact points that need to make contact in order to register a keystroke. 

Mechanical switches can also be fast, but they require a certain amount of force to actuate, which can slow down typing or gaming speeds. 

However, some people prefer the tactile feedback and slower actuation speed of mechanical switches for a more deliberate and precise typing or gaming experience.

Price Point

The price of a keyboard switch can vary widely depending on the switch’s brand, type, and quality. 

Generally speaking, mechanical switches are more expensive than optical ones, as they are more complex and require more materials to manufacture. 

However, there are affordable options for both types of switches, and it is possible to find a high-quality keyboard with either switch at a reasonable price.

Sound of Clicks

One of the most distinctive features of mechanical switches is the audible “click” or “clack” produced when a key is pressed. 

Some people find this sound satisfying and enjoyable, while others find it distracting. 

Optical switches do not produce as much sound as mechanical switches, which can be a pro or a con depending on your preferences.

Modding Ability

Mechanical switches are highly moddable, which means they can be customized and adjusted to suit individual preferences. 

It is possible to change the keycaps, springs, and other components of a mechanical switch in order to create a unique and personalized typing or gaming experience. 

Optical switches are not as moddable, as they are designed to be more streamlined and consistent.

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. Online retailers such as Amazon, Newegg, and Best Buy typically offer a wide selection of optical and mechanical switches, complete keyboards, and DIY keyboard kits. 

Additionally, local computer stores may carry a selection of switches for purchase.

When considering availability, it’s important also to consider the availability of replacement switches or parts. Some keyboard models may require specific switch types, and it’s important to ensure that replacement switches are readily available in case of malfunction or damage.
