1. A controllable power-economizing extension sockets comprising:
- a socket body comprising, a main control socket and a plurality of interactive sockets spaced apart and connected in parallel;
each input of each interactive socket being connected to one electrode of an AC source;
a voltage stabilizer having one terminal connected to said main control socket and another terminal to another electrode of another electrode, said voltage stabilizer consisting of a voltage stabilizing element and a reverse diode connected in parallel to each other, a capacitor connected to two terminals of said voltage stabilizer in parallel, an electro-magnetic switch connected to two terminals of said capacitor and said two parallel terminals in parallel, said electro-magnetic switch having a contact switch connected to an output of each of the interactive sockets, wherein said voltage stabilizer supplies a constant voltage to said electro-magnetic switch to operate in case of a main electric or electronic appliance having its plug inserted in said main control socket turned on or off, said interactive sockets synchronously turned on or off with said main control socket, wherein said electro-magnetic switch is a relay containing a coil and a switch; and
said voltage stabilizing element is a Zener diode.

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.
