Two socket female heads 3 for household appliances to be plugged in are also connected to the housing 1, and a control circuit board 4 is fixedly arranged inside the housing 1, and a controller 5, a power conversion module 6, a wireless signal transceiver module 7 and relays 8 corresponding to the socket female heads 3 are arranged on the control circuit board 4. The input end of the power conversion module 6 and the input ends of the two relays 8 are respectively connected in parallel to the positive and negative terminals of the socket male head 2, and the positive and negative terminals of the two socket female heads 3 are connected to the positive and negative output ends of the corresponding relays 8. The controller 5 and the wireless signal transceiver module 7 are respectively connected to the output end of the power conversion module 6, and the power conversion module 6 can convert AC power into 12V or 5V DC power for use by the controller 5 and the wireless signal transceiver module 7. The controller 5 is also connected to the control end of each relay 8 to control the on and off of each relay 8. The user can use a mobile phone or other wireless signal sending device to send a signal to the wireless signal transceiver module 7. After receiving the signal, the wireless signal transceiver module 7 sends it to the controller 5. The controller 5 controls the designated relay 8 to be turned on or off according to the signal instruction.
