These stark and elegant Black Windowed Lamp R4 Keycaps are made of opaque black plastic with a small cutout in the south-center edge that wraps around the top and bottom. The cut-out has a clear plastic window to allow an LED installed under the switch to glow through. These are somewhat rare to find, but they have a little bit of the je ne sais quoi to your keeb or macropad build
Snaps onto any Cherry MX or compatible switch. It's R4 profile so will work nicely as a stand-alone key or at the top row of your keyboards.
Note: This product is a single keycap, and key switches are not included!

Jargon buster

Plain-language definitions for the technical terms used above.

LED
A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
