为了节约电能，延长路由器使用寿命，设计一种办公室用计算机与路由器同步开关的装置，只要有一台计算机开机，就能自动打开路由器工作电源，最后一台计算机关机，又能自动关闭路由器电源。此设计利用计算机双绞线中四根备用线中的其中两根，引出计算机USB接口的5V电源控制继电器吸合，从而控制路由器开关，实现路由器与计算机工作同步。

A synchronous switch for router and connected computers used in office is designed in order to save electricity and extend the service life of the router. The synchronous switch could automatically turn on the router when any one computer is turned on, and turn off the router when all the computers are turned off. This design utilizes two of the four spare wires in the twisted pairs used in computer to lead out the 5V power supply from the USB interface to control the switch of the relay, thereby controlling the switching of the router and achieving the synchronous working of the router and the computers.
