You come home from the supermarket and are get the shopping out of the car. Arms full, you take it into the pantry. Reliably, conveniently and without the need to touch it, the product easily automatically switches the light 'on' and 'off' again as soon as you leave the room. The intelligent switch is particularly good for corridors, kitchens, guest WCs and other service rooms. Incidentally, installation couldn't be easier. Using it to replace your conventional switches is as easy as putting icing to a cake, whether as a 2-wire or 3-wire installation.
