The TK96 at an angle: a black board with a gold edge, a tall frosted clear keycap over a keyboard switch with a white housing and a pale blue stem, two round LEGO holes near the bottom corners, a right-angle four-pin header out of the bottom edge, and a small resistor beside it.

Mechanical Key and LED

A keyboard switch with a WS2812 RGB LED under its clear keycap, as two separate circuits: the key reads HIGH when pressed through its own 10 kΩ pull-down, and the LED shows whatever colour your sketch sends it. VCC is your board's logic voltage.

Turn it over and see all four holes wired: BUTTON is the key's side of the switch with a 10 kΩ pull-down, WS2812 the LED's data input. Look under the keycap for the 2 mm LED that lights it.
