You should care more about the stabilizers in your mechanical keyboard—here’s why

While most people don't spend a lot of time thinking about the keys they tap all day, mechanical keyboard enthusiasts certainly do. As interest in DIY keyboards expands, there are plenty of things to obsess over, such as keycap sets, layout, knobs, and switches. But you have to get deep into the hobby before you realize there's something more important than all that: the stabilizers.

Even if you have the fanciest switches and a monolithic aluminum case, bad stabilizers can make a keyboard feel and sound like garbage. Luckily, there's a growing ecosystem of weirdly fancy stabilizers that can upgrade your typing experience, packing an impressive amount of innovation into a few tiny bits of plastic and metal.

What is a stabilizer, and why should you care?

Most keys on a keyboard are small enough that they go up and down evenly, no matter where you press. That's not the case for longer keys: Space, Enter, Shift, Backspace, and, depending on the layout, a couple more on the number pad. These keys have wire assemblies underneath called stabilizers, which help them go up and down when the switch does.

A cheap stabilizer will do this, but it won't necessarily do it well. Stabilizers can be loud and move unevenly, or a wire can even pop out and really ruin your day. But what's good? A stabilizer is there to, well, stabilize, and that's all it should do. It facilitates smooth up and down movement of frequently used keys—if stabilizers add noise, friction, or wobble, they're not doing their job and are, therefore, bad. Most keyboards have bad stabilizers.

Like switches, most stabilizers are based on the old-school Cherry Inc. designs, but the specifics have morphed in recent years. Stabilizers have to adhere to certain physical measurements to properly mount on PCBs and connect to standard keycaps. However, designers have come up with a plethora of creative ways to modify and improve stabilizers within that envelope. And yes, premium stabilizers really are better.
