What to Look for in Optical Switches
While optical switch manufacturers are relatively few, there is a wide range of options out there that might confuse you.
So, when deciding on the best optical switches for you, keep the following factors in mind.
Feel
To be honest, the feel of the best optical switches is entirely up to you. Like standard switches, optical switches come in three different key feels including Linear, Tactile and Clicky.
For gaming, the benefits of a linear optical switch don't need an introduction. It delivers consistent, smooth, and precise actuation to give a better experience for gaming. Indeed, misfires and discrepancies would be disastrous during the big battle!
For those interested in tactile feedback, Halo Clear switches pair well with OEM keycaps, offering a satisfying typing experience.
For typing, you'll need keypress assurance, which the tactile switch provides with its mild resistance and sound.
Sound
Go for the best optical switches with linear feel if you value a quiet space for your high focus. Whereas, if you enjoy fun clicky noise, give clicky optical switches a try. They offer a similar feel to tactile switches, but they have that unique loud and clicky sound.
If you're looking for something more specialized, exploring the best low profile switches can also help you find the right keycaps for your needs.
Faster response time
As you may know, what makes optical switches superior to mechanical switches is their lightning-fast response time. They will give users an edge in every gameplay, even in fiery battles.
For example, Razer clicky optical switches produce the fastest response time in gaming at 0.2 milliseconds — 10 times quicker than regular mechanical switches.
This is because an LED light is preventing an optical sensor from being touched. When pressing the key, you remove the blockage from the sensor, allowing light to reach it. Finally, the needed time for the light to correctly hit the sensor is just approximately 0.2 ms.
Durability
Most optical switches have a longer lifespan than conventional mechanical switches. For example, Gateron optical switches all boast a lifetime of up to 100 million keystrokes.
In addition, some other optical switches can only survive after 80 million keystrokes. Even so, this number is also the desire of most traditional mechanical counterparts.
If you are interested in learning about mechanical switches, we’ve revealed all of their secrets in this post.
No wonder! You can go confidently into every battle with the best optical switches. While they are still a new player in “the switches game”, the best optical switches will become the winner soon.
