This embodiment provides a dual-power supply disturbance-free synchronous switching device, which can realize most dual-power supply disturbance-free synchronous switching devices currently on the market. When in use, there are gaps at the connection of the shell and it is difficult to ensure complete wrapping, resulting in poor shielding effect.
