What Is a Hot-Swappable Keyboard?

If you're just starting to get into mechanical keyboards, you might have heard the term "hot swap" thrown around. But what does it actually mean?

Understanding Key Switches

Before we get into hot-swapping, you first need to understand what key switches are (often shortened to "switches").

A key switch is the individual component under each keycap that registers when a key has been hit. (A "keycap" is the part of the key that you see on a keyboard β€” the housing, often plastic, that your fingers tap.)

Mechanical keyboards use mechanical switches, which are beloved among keyboard enthusiasts for the satisfying feel and sound. You'll notice those feel different than the keyboards on the average laptop, which use scissor switchesΒ or membrane switches.

Consider the difference between Freewrite's Smart Typewriter and Alpha keyboards (which have mechanical switches) and Traveler's keyboard (scissor switches). Watch the video below to see the difference in action.


Hot-Swapping

Now, people who type a lot often have a key switch preference. (You might not even know you do!) There are all kinds of different key switches that vary in feel, sound, and price.

On most commercial keyboards, the key switches are soldered directly onto the circuit board. So if you wanted to change your switch type, you'd need to desolder and resolder each individual switch. It's an annoying and time-consuming process.

A hot-swappable keyboard, however, is one that allows you to easily change out the switches without the need for soldering. They use special sockets that let you pull out and replace switches with just a simple switch puller.

There are a range of switches available for mechanical keyboards, and you can learn more about them here.

Whether you're experimenting with different switch feels, replacing a faulty switch, or customizing your typing experience, hot-swappable keyboards make it easy.

In short, a hot-swappable keyboard is perfect for anyone who values flexibility, ease of customization, or just wants to dip their toes into the world of mechanical keyboards.

It’s the ultimate plug-and-play solution for keyboard enthusiasts and newcomers alike.

For the release of Sailfish, our new firmware update for Smart Typewriter Gen3 and Traveler, we created a brand-new boot-up animation to surprise and delight our writers.

We worked with talented Danish animatorΒ Mathias Lynge to bring our experience of the writer's journey to life.

We had a blast visualizing the writer's journey in this new way. Our engineers also had a blast (or something less than a blast)Β figuring out how to adjust this fun, playful animation to E Ink's very tricky specifications. Hello, refresh rate woes! But we think the result is pretty fun.

"The little animation made my day when I noticed. I love a good flourish."

- Freewrite user

The process of creating this animation was long and full of Zoom calls where we deeply discussed the writing process. We were struck through those conversations by how much overlap there is in creative processes of all disciplines.

So we sat down to chat with Mathias about his creative process and what it's like being a full-time animator.

ANNIE COSBY: Let's start with the basics. What kind of art do you make?

MATHIAS LYNGE: I'm a 2D animator and motion designer working freelance with a wide range of clients.Β The style varies depending on the project, but it’s usually either a hand-drawn look animated frame-by-frame on a drawing tablet, or a more digital, vectorized look made in After Effects.

While much of what I do is commercial work, I try to keep up with my own passion projects as well. That could be a 10-second Instagram loop of a nature scene, or an interesting character design I’ve sketched down with a pencil. It’s there that I get to sharpen my skills and try out new techniques, which often find their way into later client projects.

AC: You often share educational content on social media for other artists.Β Are you formally trained, or did you teach yourself?

ML: I’m mostly self-taught. I’ve been drawing for as long as I can remember, but it wasn’t until I went to university that I realized drawing could become a career.

When I first heard terms like β€œmotion design” and β€œThe 12 Principles of Animation” I was on a student exchange program at UCSB in California, where I had chosen a class called "Introduction to Animation." It was a big eye-opener for me, and from that point I was hooked.

But it’s mainly been online YouTube tutorials and my existing drawing experience that have taught me what I know.

Now, I have a big presence on social media, where I share my art as well as educational content centered around animation in Adobe After Effects, so I guess you could say that I'm also an animation influencer!

I’ve been drawing for as long as I can remember, but it wasn’t until I went to university that I realized drawing could become a career.

AC: That's actually how I first found your work. Do you have any specific artists who inspire you?

ML:In the world of 2D animation, I have a list of personal heroes that inspire me with their unique style: Reece Parker, Ariel Costa a.k.a. BlinkMyBrain, and Tony Babel, to name a few.

I also find a lot of inspiration from illustrators and painters I discover online, on platforms such as Pinterest. Last year I made a sparkling water animation that was heavily inspired by Cornwall-based artist Gordon Hunt. He makes these beautiful nature-inspired pointillist paintings that capture how light hits the ocean using colorful dots of paint. I tried to recreate that effect using After Effects to bring it to life, and it led me to a whole new way of animating within the program.

AC: Where else do you draw inspiration to create your work?

ML: I’m heavily inspired by the nature and cityscapes around me in Copenhagen, and I find that taking long walks through parks or down the streets of my neighborhood really sparks my imagination.

I’ll often carry around a sketchbook to quickly scribble down an idea or a loose sketch of something I find interesting, such as seeing how the light from a lamppost hits the surrounding leaves, or how the wind moves the tree in a certain way.

Then I’ll think to myself, β€œI wonder if I can recreate that motion using a specific technique in After Effects?”

I’m heavily inspired by the nature and cityscapes around me in Copenhagen...

AC: What does your daily routine look like as a full-time artist?

ML:Β It varies a lot, but I’m usually either working hard on a client project or tinkering away with a new animation tutorial for my social media channels.

I love being able to switch between the two, and when I’m going through a client dry spell, I find that staying creative and posting animation-related content helps keep me inspired while also putting things out into the world that may lead to my next client down the road.

AC: What's your #1 piece of advice for animators new to the industry?

ML: Keep experimenting and trying out new techniques. There’s no such thing as running out of creativity, and even though many of the things you try don’t necessarily go anywhere, it’s all experience that adds up and expands your toolbox. It’s a muscle that needs to be worked out regularly.

Plus, you’ll have more awesome animation to choose from when you’re putting together your next showreel or portfolio!

There’s no such thing as running out of creativity...

AC: What's one fun fact about you completely unrelated to animation?

ML:I’m a big sucker for history podcasts, especially if they are about ancient civilizations, such as The History of Rome by Mike Duncan.

I find it fascinating to hear how mankind was able to build such great empires without ever knowing what electricity, cars, or the internet are.
