The smart roller shutter switches work with a touchscreen. A light touch to the stylish panel is enough to control the smart roller shutter switch up or down. The smart roller shutter switches are equipped with two touch buttons, one of which is up and the other for down. 

With a single touch to the smart roller shutter switches, the roller shutter will go up/down completely automatically. When you touch the smart roller shutter switch again, it will stop at the position where the roller shutter is at that time.
