Summary:The utility model discloses a two-in-one mechanical interlock with a spare power automatic switching function. At least two closing switches; the device further comprises a fixing frame, the fixing frame is provided with a latching electromagnet which is electrically connected with any closing switch, and the latching electromagnet is provided with a blocking piece which can stretch out or retract. The two-in-one mechanical interlocking device has the beneficial effects that the two-in-one mechanical interlocking device adopts corresponding electrical logic to realize the two-in-one mechanical interlocking of the inflatable cabinet, the wiring is simple, the reliability is good, the structure of the cabinet body does not need to be changed, the cost does not need to be increased too much, and the reliability is high. Two-in-one mechanical interlocking can also be realized, and the defect that the spare power automatic switching comprehensive protection cannot realize mechanical interlocking can also be overco
