Power frequency withstand voltage detection device

The invention relates to the technical field of withstand voltage detection of electric appliance switches, in particular to a power frequency withstand voltage detection device, which is characterized in that an on-off converter and a plurality of wiring breakers are arranged in a rotating bottom shell along two sides of the rotating bottom shell; the on-off converter comprises a grounding contact connected with the ground wire interface, a high-voltage contact connected with the power interface and a wiring contact plate, and the grounding contact and the high-voltage contact are connected with the wiring contact plate through a change-over switch; the wiring conduction device comprises a telescopic part, and a conductive clamping plate is arranged at the outward extending end of the telescopic part; and the wiring touch plate is connected with the conductive clamping plate through a switch-on wire. The on-off converter realizes on-off from the grounding contact to the wiring contact plate or from the high-
