The mine local control box adopts a composite structure consisting of a flameproof housing and an increased safety housing. It is usually welded from steel plates and sprayed with plastic on the surface. The internal components include flameproof control switches, control buttons, explosion-proof signal lights, and various overload meters. These internal components can be arranged according to the actual needs of the user to achieve a variety of functions. The signal lights are available in red, green, yellow, white and other colors, and the instruments can be selected at will, such as ammeters, voltmeters, temperature controllers, tachometers, etc.
