The invention discloses a switch cabinet hinge which is characterized by comprising a front plate and a rotating plate. The front plate is attached to and fixedly connected with a door plate back sidewall, one end of the rotating plate is rotationally connected with the front plate, and the other end of the rotating plate is fixedly connected with a switch cabinet shell. According to the switch cabinet hinge, a non-welding manner is adopted for fixing, the machining process is simple, the assembly efficiency is high, the size consistency is good, the door plate fastening strength is high, andthe overall protection stage of the switch cabinet is high; the front plate and a base plate are clamped and fixed to the door plate through a nut or screw, the original welding screw fastening manner is improved, the door plate fixing strength is greatly improved, and the problems of door plate drooping and coincident appearance which are caused by insufficient hinge fastening strength or coincident fixing positions are effectively solved.
