Black Windowed Lamp R4 Keycap for MX Compatible Switches

via Adafruit
$10.05
SKU AF-5112

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!
