An integrated controller for electronic apparatuses includes a host and an AC/DC converting module. The host includes at least one power terminal set to connect to an electronic apparatus. The power terminal set includes a power input terminal, a power output terminal and a power neutral terminal. The power input terminal is connected to a fire wire to receive AC power. The power output terminal is connected to a wire-input end of the electronic apparatus, and the power neutral terminal is connected to a wire-output end of the electronic apparatus. Therefore, the AC/DC converting module receives the AC power via the power input terminal and the power neutral terminal and converts the AC power to DC power which is required by the integrated controller. The integrated controller is mounted in an original position for a wall-embedded switch is positioned to replace the wall-embedded switch.
