[0002] In the prior art, a controller module and a relay module are usually provided on a circuit board, and the controller module and the relay module are electrically connected, and the operation of the relay module is controlled by the controller module. Generally, in order to better control the loop between the controller module and the relay module, a switch module is usually added to the loop. When the switch is closed, the loop between the controller module and the relay module is connected, and the relay module is controlled by the controller module; when the switch is disconnected, the relay module is not controlled by the controller module. However, this design method in which the relay module is completely "bound" to the controller module has many defects. For example, one of them is that the relay module does not want to be controlled by the controller module, but the relay module still needs to continue to operate. This circuit board cannot meet the requirements. Summary of the invention
