Manual maintenance switch

The invention discloses a manual maintenance switch which comprises a plug assembly and a socket assembly, a handle is arranged on the plug assembly, the plug assembly is matched with the socket assembly, the plug assembly and the socket assembly are connected through the handle and are locked twice through the handle, and a plug pin structure is arranged on the socket assembly. The plug pin structure is arranged at the bottom of the socket, the plug pin structure is located in the stress direction of the socket contact master slice, the plug pin structure is guided in through the sliding rail on the socket shell, and the plug pin structure is locked by the first fixing protruding block and the second fixing protruding block on the socket assembly and is firmly limited. At the moment, the power component is stably fixed in the socket shell due to the baffle plate, and the bolt structure can provide stable anti-retreat jacking force for the socket contact master slice, so that deformation caused by lack of the
