Product Operation Guide

When the finger presses the crystal key, the metal dome contacts the contact of the circuit, closing the circuit;

When the finger releases the key, the metal dome separates from the contact of the circuit and opens the circuit;

When the side lights are powered on, the LED lights on.

The light passes through the light guiding film to light the designated area, and then evenly emits light through the reflective film and diffusion film to illuminate the key area.
