  • Controllable power-economizing extension sockets
    Patent number: 6573619
    Abstract: A controllable power-economizing extension sockets includes a socket body, a main control socket and plural interactive sockets formed properly spaced apart in the socket body, a voltage stabilizer, and a capacitor and an electro-magnetic switch connected between the input terminal of power and the main control socket. The electro-magnetic switch is connected to each of interactive sockets to form a control circuit. The voltage stabilizer supplies a constant voltage to let the electro-magnetic switch operate to let the interactive sockets for peripheral electric or electronic appliances turned on or off synchronously with the main control socket.
