DCX vs DCD vs DCL - Drop’s Keycap Profiles Explained

This is a summary of how alternative layouts have been supported by kits such as Colevrak and Homing. It is not a discussion of alt layout performance and development, but if that interests you I highly recommend starting with Pascal Getreuer’s A guide to alt keyboard layouts (why, how, which one?). It’s a concise and comprehensive overview with links to some great sites that go deeper. He also has a separate Links about keyboards page. The Keyboard layouts doc he recommends explains layout goals and metrics in detail, summarizing the alt layouts discussed here as well as more than one hundred others. Sculpted-profile The majority of custom keycap sets are sculpted-profile (Cherry, SA, MT3, KAT, etc. - more on profiles generally here) so let’s start there. Because each row has a unique keycap shape, alt layouts require a unique keycap for each legend that moves off its QWERTY row. At first there were two The Dvorak layout was patented in 1936 by August Dvorak & William L....

Figure 1: Sometime around here is a good time to ask that question... If you’re new to the mechanical keyboard hobby, I have no doubt that planning your first keyboard build is a bit of a daunting task. To be entirely honest with you, it’s only a tiny bit less daunting for your second or even third keyboard builds should you stay around a little while longer. You’ve got the keyboard itself to worry about, stabilizers, keycaps, and even switches on top of all of the intangible marks you want your dream keyboard to hit. Switches are especially daunting right out of the gate as there’s just so many options out there to pick from – each with their own unique specifications, manufacturers, and more. Yet, in spite of all of these differences between switches, time and time again I find people always asking about lubing switches as one of their chief concerns when it comes to picking some up. With countless numbers of content creators talking about lubing switches, its no...

We’ve covered the basics of keycap profiles before—spherical/cylindrical, sculpted/uniform, etc. One thing that has come up more and more over the years as we’ve expanded our portfolio of offerings here at Drop is the distinction between some of our similar profiles. Specifically, what is the actual difference between DCX, DCD, and DCL? Cylindrical Profiles To recap the previous article on the topic, one of the most basic ways to separate various keycap profiles is by shape (cylindrical, spherical, or flat). DCX, DCD, and DCL are all cylindrical profiles. The most famous cylindrical profile is Cherry profile, as defined by the original manufacturer of the keycaps—Cherry. GMK now owns those tools, and as such, only they can technically claim to produce “Cherry” profile keycaps. Similar keycap profiles are often called Cherry profile colloquially, but are in actuality slightly different. For the sake of not splitting hairs, all of the cylindrical profiles discussed here are...

One of the oldest questions, albeit one you don’t see very often anymore, is about 3-pin and 5-pin MX switches. Early in the custom switch scene, budding enthusiasts would need to determine whether their keyboard needs 3-pin or 5-pin switches. Today, the question doesn’t appear as often as it used to, but it is still important to know the difference and when one is a better choice. The difference between these two types of switches is in the name, the number of pins. As seen in the pictures below, 3-pin switches have two metal legs for the contact leaves and registering of switch presses as well as the stem pole. These switches were traditionally called plate mount switches, as they relied on the plate to align the switches on the PCB. 5-pin switches have the same contact pins and stem pole but are also accompanied by two additional alignment pins on the left and right of the stem pole. These were called PCB mount switches, as they could be used without plates as the PCBs would...

Figure 1: I couldn't think of a more literal way to represent this article if I tried... Looking back just a few years ago, there’s no doubt that the huge influx of people that joined the hobby at the peak of the COVID pandemic were drawn to keyboards by way of YouTube, TikTok, and other audio-visual content platforms. Even as the output from these content creators has waned in recent months, their collective impact and legacy on the keyboard hobby is rather firmly etched in the history books. As a result of all of their sound tests, build logs, and opinion videos, the message is clear to any new person joining the hobby: mechanical keyboards are all about the sound. Thock this, clack that. Whether it’s keyboards, keycaps, or even singular switches, seemingly everyone new to the hobby meticulously pores over each component of their keyboard not in an attempt to figure out how it will feel in hand, but how it will sound as they’re furiously grinding their way out from...

As I walk down the hall to my office each morning, I hear the discordant clattering of keys coming from my coworker’s office. In the hall… several doors down… I hear them. Like the loose teeth in my grandma’s poodle, barely hanging on, they rattle and heave. If anyone’s ever told you that mechanical keyboards are too loud, it’s simply because that person has become completely desensitized to the garbage-bomb that is the standard office computer keyboard. In the 1980’s and 90’s, it was common to hear the sound of unmitigated excellence when you walked into an office building. The rapid gunfire-like precision of a room full of high-quality computer keyboards firing in unison. Even in the early 2000’s when I worked in a south-side Chicago newspaper newsroom, it was still filled with such keyboards. Ten to fifteen years into their professional daily use, they were still magnificent in sound and feel. Punctual, clean, decisive. In those days, professional keyboards didn’t come...
