Abstract

The utility model discloses a push-on type electrical adapter, comprising a main housing and two plugs of different standards that can be extended or retracted. The top surface of the main housing is provided with a socket hole. Two first conductive arms, two second conductive arms, two rotating switching parts and two adapters are provided in the main housing. The adapter and the rotating switching parts can be disconnected/connected with each other. When one of the plugs moves, it can toggle the rotating switching part to swing, thereby controlling the disconnection/connection function between the adapter and the rotating switching part. With this structure, not only can the plug that is extended alone have a normal transfer function, but also when the two plugs are extended at the same time, only one plug has a transfer function, and the other plug is not connected to electricity. In this way, it can effectively avoid electric shock accidents caused by the two plugs that are extended at the same time being charged, prevent the safety hazards caused by idle plugs, and ensure the safety of the adapter.
