Abstract:
1. A power strip system, comprising: a master control socket; at least one subsidiary socket, the power on/off status of the subsidiary socket being decided by a current of the master control socket; a current detecting unit connected with the master control socket for detecting the current of the master control socket and sending a corresponding current signal according to the detected current; a control module receiving and analyzing the current signal sent by the current detecting unit and then generating a corresponding control signal; a voltage regulating module providing a regulated voltage for the control module, the regulated voltage acting as a power supply of the control module; and a switch module including a switch device and a switching unit controlling the switch device to turn on/off the subsidiary socket according to the control signal of the control module; wherein the switching unit has two parallel branches each including a bridge rectifier, an electromagnetic valve connected between the bridge rectifier and the switch device, and a silicon-controlled rectifier connected between the bridge rectifier and the control module for receiving the control signal from the control module and driving the bridge rectifier and the electromagnetic valve to turn on/off the switch device.
