  • Smart switch apparatus
    Patent number: 11716080
    Abstract: A smart switch apparatus is coupled between a live wire of an indoor power and two output terminals of a SPDT (Single Pole Double Throw) switch. Two ends of a load are respectively connected to a neutral wire of the indoor power and an input terminal of the SPDT switch. The smart switch apparatus includes an on-off status detector, a switch position detector, a controller, an on-off controller and a power circuit. The on-off status detector is coupled to the live wire of the indoor power for generating an on-off status signal. The switch position detector is coupled to the two output terminals of the SPDT switch for generating a switch position signal. The controller is coupled to the on-off status detector and the switch position detector for receiving the on-off status signal and the switch position signal.
