how it works
When a switch is switched down, the light is turned off and it acts as a hanger. When a switch is switched up, the light is turned on and it acts as a lamp. The act of switching up and down becomes the on and off functions, eliminating the need for buttons.
The bottom of each aluminum switch has a triangle cutout, where the light emits from. Due to the cutout shape on all 7 switches and the angle of how the light hits the wall, when the switches are on/off in an alternating sequence, it creates interesting diamond-shaped patterns on the wall.
