The invention relates to a method for preventing and treating broiler chicken coccidiosis with a switch. The method comprises the following steps: cutting raw radix glycyrrhizae, radix stephaniae tetrandrae, fructus evodiae, periostracum cicadae, fructus forsythiae, rhizoma bletillae, rhizoma ligustici chuanxiong, cantharellus cibarius, radix trichosanthis, and semen descurainiae into 1-2 centimeters long according to certain parts by weight, wherein the release of medicine properties during decoction is facilitated; adding water with a volume of 30-35 times, and carrying out decoction for 2-3hours, wherein the temperature of the first hour is controlled to be in a range of 150-200 DEG C, and then the temperature is controlled to be in a range of 100-120 DEG C; and carrying out natural cooling to room temperature after the decoction; and placing the obtained medicine into a refrigerator of 0-5 DEG C. A cabinet body of a switch cabinet is connected with a vertical plate with a bottom fixedly connected with the ground surface, and the connected structure comprises an assembling part assembled on the vertical plate and the cabinet body assembled on the assembling part. The method effectively avoids the defect that difficulty exists when workers need to climb up for operation in the prior art, the distance between the bottom end of a switch cabinet and the ground surface is 3-4 meters under a fixed connection framework mode, and a switch is not easy to view.
