What is it used for? : 

It is used to preserve energy and its for people who are a bit scared to switch off and go up the stairs, espescially people who watch horror movies before they go to bed. In this innovation there are two DPDT (Double Pole Double Throw) type switches, when you are about to go up the stairs (At The Bottom) you switch on the light and at the top of the stairs (At The Top) there is another switch so you can turn off the light. 

Pretty handy if you ask me!
