Grounding knife-switch centrally-mounted load switch combined electric appliance

The invention discloses a grounding knife-switch centrally-mounted load switch combined electric appliance comprising a rack which is a common support frame of a load switch and a grounding switch; the load switch comprises a switch body, an upper contact assembly and a lower contact assembly, the lower contact assembly is electrically connected with the switch body, and a conductive cylinder of the switch body can move in a lifting mode and is electrically connected with or disconnected from the upper contact assembly to form a closing or opening state of a main loop. In an opening state, one end, close to the upper contact assembly, of the conductive piece is partially exposed to form a grounding action part; the grounding switch is arranged between the upper contact assembly and the conductive member. In an opening state, the grounding switch is electrically connected with the grounding action part of the conductive cylinder to form a grounding loop. The grounding switch is arranged on the inner side of th
