The wireless receiver has a second identification card pluggably mounted therein. The wireless assembly can achieve a remote control by a low power consumption wireless transceiver module and matches the wireless switch to the wireless receiver via the identification cards, thus eliminating the need for complicated control wiring, therefore greatly reducing the complexity of wiring, saving electric wires and cables, and reducing cost.
