Numerical control mining explosion-proof and intrinsically safe vacuum combined feed switch

The invention relates to a numerical control mining explosion-proof and intrinsically safe vacuum combined feed switch that comprises an explosion-proof shell and an operating device used for connecting and disconnecting the switch body and a main circuit terminal group. The explosion-proof shell comprises a front plate, a rear plate and side plates. An explosion-proof partition plate is arrangedbetween the front plate and the rear plate. The explosion-proof shell is divided into a main cavity and a wiring cavity by the explosion-proof partition plate, the interior of the main cavity is divided into a plurality of small cavities through transverse partition plates and longitudinal partition plates, the switch body is arranged in each small cavity, and a main circuit terminal group is arranged at the position, corresponding to the switch body, of the explosion-proof partition plate. By adopting the technical scheme, the multi-loop feed switch is modularized and combined; circuits of the multi-loop feed switch
