The electrical box assembly as claimed in claim 1, wherein the button comprises a needle seat and an indicator light, the PCB board comprises a communication interface module, the needle seat and the indicator light are electrically connected to the communication interface module, the communication interface module receives information transmitted by an external component inserted on the needle seat to update a program of the controller, the communication interface module obtains operating status information of the motor, and the indicator light outputs different indications according to the operating status information.

6. The electrical enclosure assembly of claim 5, wherein the indication output is a number of blinks of the indicator light, and the operational status information includes a speed, power, current, or/and voltage of the motor.

7. The electrical enclosure assembly of claim 1, wherein the dial switch includes a first switch and a second switch each having an on state and an off state, the PCB board includes an address code module electrically connected to the dial switch, the address code module determines an address of a controller according to switch information of the dial switch, and determines that the controller has different addresses by toggling the first switch and the second switch to obtain different switch state combinations.

8. The electrical enclosure assembly of claim 7, wherein the PCB further comprises a local control module electrically connected to the button and the address code module, the local control module directly controlling operation of the motor according to local operation information received from the button and the address code module.

9. An appliance cartridge assembly according to claim 8, wherein the keys comprise a first key and a second key, the first key, the second key, the first switch and the second switch being collectively operated to determine the local operation information for receipt by the local control module, different switch state combinations of the first switch and the second switch being used to determine a turning direction, a rotational speed or/and a power of the motor, the first key and the second key being used to determine an increase and a decrease of the rotational speed of the motor or to determine a start and a pause of the motor, respectively.

10. An air conditioner, characterized in that the air conditioner comprises a motor and an electrical box assembly as claimed in any one of claims 1 to 9, wherein the motor is electrically connected with the PCB board.
