I like this product very much. This switch extends the turning-on time automatically when it detects motion. My previous motion detection SW did not have this feature and was very inconvenient. The delivery was very fast. Unfortunately there is also a weak point with this item, which is lacking in explanation for the wires of the SW output. There are 3 wires, blue, yellow and white but the wiring drawing on the product shows only 2 wires. Also there isn't any explanation for this at the item description from the seller. Because of this lacking I needed to test the wires with a volt meter. However, I still do not know what the yellow wire is for. If this description was provided, then certainly my evaluation would be 5 stars. The white and blue wires worked as the power supply to a load from this switch.
