Free Touch / Light switch concept

Free Touch
Free Touch

In our home, there are many lights switch, most of them can’t move, which brings us a lot of inconvenience. You need to go to a fixed place to turn off or turn on the lights; You need to search for the switch, not let the switch be where you want it to be; You need to lay a lot of extra lines for the switch; You may even be troubled by an irrational switch position for a long time. "Free touch" is a new type of wireless switch. The switch cosists of a small wafer with a new type of human body pressure sensing technology. You only need to attach it to anything you think is reasonable, and then do some natural touch, and it can light your lamp.
