An intelligent timer switch (100) includes a main control circuit (102), an interface circuit (103), a power supply circuit (104) and a display circuit (105); in which the main control circuit (102) is used to realize conditional control of the timer switch (100); and the interface circuit (103) is used to connect the electrical equipment with a compressor and collect the operation status of the electrical equipment to provide the main control. The circuit (102) also receives the control signal of the main control circuit (102) for switching control of the electrical equipment; the power supply circuit (104) is used for the voltage required by the main control circuit (102), the interface circuit (103) and the display circuit (105). When the time arrives at the set power supply time, the intelligent timer switch (100) delays for a period of time to turn on the relay and supply power to the equipment; before the time arrives at the set power cut time, the operation state of the electrical apparatus is detected in advance, and after the compressor stops, the relay is disconnected to power the equipment. The intelligent timer switch (100) can switch electrical equipment at regular intervals and protect electrical equipment through condition judgment when switching.
