Our unconventional switch is made out of a mechanical keyboard key, a glass cup/coaster, and a green led connected by alligator clips beneath the coaster and glass. The intent of our switch is both aesthetic and practical, with the green light creating a cool effect in the dark and also useful for signaling if you still need a drink and don't have one. By default, the LED is off but when the key is pressed its turned on. We used a mechanical keyboard key because of its portability, allowing the user to have a low-profile switch at their table for their drink light.
