Hey guys! Ever wondered what makes Keychron keyboards so special? Well, a big part of it lies in their awesome optical switches! In this guide, we're diving deep into everything you need to know about Keychron optical switches, from what they are and how they work, to the different types available and why you might want to choose them for your next keyboard. So, buckle up and let's get started!

What are Keychron Optical Switches?

So, what exactly are Keychron optical switches? Unlike traditional mechanical switches that rely on physical metal contacts to register a keystroke, optical switches use light. Seriously! Inside each switch, there's an LED and a light sensor. When you press a key, you're essentially breaking a beam of light, and that's how the keyboard knows you've pressed the key. Pretty cool, right?

The magic behind optical switches lies in their actuation mechanism. Instead of physical contact, these switches use a light beam. When a key is pressed, it interrupts the light beam, which is then detected by a sensor. This triggers the signal to register the keypress. Because there's no physical contact involved, optical switches are incredibly fast and responsive. This makes them a favorite among gamers and typists who need every millisecond advantage they can get. Plus, the lack of physical contact reduces wear and tear, leading to a longer lifespan for the switches.

The design of Keychron optical switches also contributes to their unique feel. They often have a smoother, more consistent keypress compared to mechanical switches. This smoothness can reduce finger fatigue during long typing sessions, making them a great choice for anyone who spends hours at their keyboard. Moreover, optical switches are less prone to the dreaded key chatter issue that can plague mechanical keyboards. Key chatter occurs when a keypress is registered multiple times due to the bouncing of metal contacts. Since optical switches don’t have these contacts, they offer a cleaner, more reliable performance. Keychron offers a variety of optical switches, each with its own distinct characteristics. From linear switches that provide a smooth, consistent feel to clicky switches that offer tactile feedback and an audible click, there’s an optical switch to suit every preference. This variety allows users to customize their typing experience to match their individual needs and preferences.

How Do Keychron Optical Switches Work?

Let's break down the science behind how these switches work. Inside each Keychron optical switch, you'll find a tiny LED (Light Emitting Diode) and a light sensor, usually a phototransistor. When the switch is in its resting state, the LED emits a beam of light that shines directly onto the light sensor. This sensor is constantly monitoring the light.

When you press the keycap, it moves the switch stem downwards. This stem has a small component that acts as an interruptor. As the stem moves, this interruptor blocks the light beam from reaching the light sensor. The moment the light sensor detects the interruption, it sends a signal to the keyboard's circuit board.

The keyboard's circuit board instantly recognizes that the light beam has been broken and registers the keypress. This all happens incredibly fast, much faster than with traditional mechanical switches. The speed comes from the fact that there's no need for physical contact to complete a circuit; the light beam does all the work. Once you release the keycap, the stem returns to its original position, the interruptor moves out of the way, and the light beam reconnects with the sensor. The sensor then signals that the key is no longer being pressed.

One of the most significant advantages of this system is its reliability. Because there are fewer moving parts and no physical contacts that can wear out, Keychron optical switches tend to last much longer than their mechanical counterparts. They're also less susceptible to issues like key chatter, which can occur when metal contacts bounce against each other. In essence, Keychron optical switches offer a more streamlined, efficient, and durable way to register keystrokes. Their reliance on light rather than physical contact makes them faster, more reliable, and longer-lasting, making them a popular choice for gamers and typists alike.

Types of Keychron Optical Switches

Keychron offers a variety of optical switches to cater to different typing preferences. Let's take a look at some of the most popular ones:

Linear Switches

Linear switches are all about smoothness. They provide a consistent, uninterrupted keypress from top to bottom. There's no tactile bump or audible click, making them ideal for fast typists and gamers who want a predictable and responsive feel. Keychron's linear optical switches, such as the Red and Yellow options, are designed to minimize resistance and provide a fluid typing experience. These switches are particularly favored in scenarios where speed and accuracy are paramount. For example, in competitive gaming, the linear feel allows for rapid and precise key actuations, giving players a competitive edge.

Linear switches are also excellent for prolonged typing sessions as their smooth action reduces finger fatigue. The absence of a tactile bump means that your fingers don't have to overcome additional resistance with each keypress, allowing for a more comfortable and sustainable typing rhythm. The Keychron Red optical switches are a popular choice for those new to linear switches due to their light actuation force, while the Yellow switches offer a slightly heavier feel for users who prefer a bit more resistance. Moreover, linear switches are generally quieter than their tactile and clicky counterparts, making them suitable for shared office spaces or late-night typing sessions where minimizing noise is important. The consistent feel across all linear switches also allows for better muscle memory development, enabling typists to improve their speed and accuracy over time.

The Keychron optical Red switch typically requires around 45g of force to actuate, providing a light and responsive feel. The Yellow switch, on the other hand, usually needs about 50g, offering a slightly heavier and more deliberate typing experience. These slight variations cater to different preferences within the linear switch category. If you're looking for a switch that offers minimal resistance and a smooth, effortless keypress, the Red optical switch might be the perfect fit. If you prefer a bit more feedback and resistance to prevent accidental keypresses, the Yellow optical switch could be a better choice. Ultimately, the decision comes down to personal preference and the specific demands of your typing or gaming style. Keychron’s commitment to providing these nuanced options underscores their dedication to meeting the diverse needs of their user base.

Tactile Switches

Tactile switches provide a noticeable bump when the key is actuated. This bump gives you feedback that the keypress has been registered, which can be helpful for accuracy and preventing typos. Keychron's Brown optical switches are a popular choice for those who prefer a tactile feel without the loud click of a clicky switch. The tactile bump in these switches provides a satisfying confirmation with each keypress, making them ideal for users who want a more deliberate and controlled typing experience.
