First, the switch cabinet is installed and used by slidingly plugging the front cabinet plate (101), the rear cabinet plate (102) and the two side cabinet plates (104) onto the mounting block (105) at the upper end of the bottom plate (103), and the front cabinet plate (101), the rear cabinet plate (102) and the side cabinet plates (104) are plugged into each other, and then the plurality of rectangular blocks (106) at the lower end of the top cover (107) are correspondingly plugged into the rectangular grooves to complete the installation of the switch cabinet; S2, sliding a plurality of H-shaped plates (204) into the strip-shaped opening, and installing components to be used on a component installation plate (205) between two H-shaped plates (204) at the same height, so that heat can be smoothly discharged through a plurality of heat dissipation ports (305) provided on the side cabinet plate (104) during daily use; S3. The annular mounting seat (206) is connected to the lower end of the top cover (107) and the upper end of the bottom plate (103) respectively, and the electric push rod (207) is installed in the annular mounting seat (206) so that its telescopic end is fixed to the side wall of the support plate (203); when the side cabinet plate (104) is subjected to an external collision, the pressure sensor transmits a signal to the electric push rod (207) and starts the electric push rod (207) accordingly, so that the support plate (203) moves outward; and the protective structure provided on the support plate (203) can protect the components inside the support plate (203), thereby reducing damage to the components.
