Traditionally, it is always troublesome for people to find matching switches for the specific lights when they’re in a room equipped with several switches on the wall. WhichSwitch is a novel sticky sign, which is designed for assisting users to find the orientation of luminaries by being attached to the switch. WhichSwitch looks like a cute tail which is made of soft, plastic and sticky materials. After it is stuck on a light switch, users can freely adjust the direction of the tail to match the location of the corresponding light.
