The switch is to to enable/disable the power supply for the OLED display and RGB LEDs.
Set it to the "on" state, and plug it into the computer. The OLED screen should display some text. If it doesn't work, toggle the switch and reconnect it to the computer. The on state for the left side is the opposite of that of the right side.

Disconnect the keyboard from the computer. Repeat the above step for L8, L9, L10, ..., L38.
An RGB LED is also required when the slot is used for an encoder. Alternatively you can bridge the DIN/DOUT pins.
Bottom of the Left Hand Side
It's recommended to solder them in order, with 3-5 LEDs each time and test.
