The Fibar Insert Switch allows controlling two independent loads both via Z-Wave wirelessly and locally utilizing a traditional wall switch. The device is placed in a wall box right behind the normal switch. The switch is not longer directly connected to the load but acts as input device for the Fibar insert that is controlling the load. The solution works with all switch design with or without neutral position as long as there is enough space in the wall box behind the switch. The device is just 15 mm height. The available space depends on the size of the traditional switch, the dimensions of the wall box and the amount of additional cabling placed in this box. This device is designed for a 3 wire system and needs a neutral wire in the wall box.
