Not All Linears Are The Same!
Figure 1: Not even all of these (mostly) KTT-made linears are the same! After all of my years of collecting, reviewing, and obsessing over switches, I can say with certainty that linear switches are the most misunderstood of all of the switch types. No, I’m not talking about mechanically either, as all of the claims of them “just going straight up and down” are somewhat kind of true. (Not too much though, don’t get that excited.) The part that is often misunderstood, though, is usually in what is being implied when people say that these switches just go straight up and down – “All linears might as well be the same.” If the title of this article didn’t make that obvious enough to you, I find that sort of idea to be completely and utterly wrong. The people who make these implications wouldn’t say that a Cherry MX Black is the same as a Novelkeys Cream switch? They also certainly wouldn’t ever claim that every Gateron-made linear is the same as every fancy TTC one out there...

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 “close enough” to Cherry that you would probably not be able to tell a difference from shape alone when typing. What differentiates DCX, DCD, and DCL then?
DCX - Drop Cylindrical “X” (ABS or PBT, double-shot (PBT can also then be dye-subbed as well)) DCD - Drop Cylindrical Dye-Sub (PBT, dye-sub) DCL - Drop Cylindrical Lumen (ABS, laser-ablated shine-through) Keysterine - Transparent ABS, UV thermal legends (unlikely to be confused for the others, included for completeness)
Left: DCD, Right: DCX A combination of material options and legending methods are what ultimately separate the three “DC” cylindrical profiles. DCX tooling can be used to make either ABS or PBT keycaps, and they will always be double-shot. DCX PBT can then be dye-subbed after injection, since the material is compatible. DCD, on the other hand, is limited to PBT material, single shot—so must be dye-subbed to impart legends on the caps. DCL is focused solely on shine-through capabilities, featuring a coated translucent base which is exposed in the legending process.
DCX Novelty Tooling
Spherical Profile Rounding out Drop’s profile portfolio is MT3, our in-house spherical profile developed in partnership with Matt3o. There are actually two different sets of MT3 tooling, for the two types of materials/legends available. This is one reason why kitting can sometimes be different depending on material choice for the keycap set. MT3 ABS - ABS, double-shot MT3 PBT - PBT, dye-sub
