Power saving switch

#The present invention relates to a power saving switch, and more particularly, to a power saving switch, which can prevent a sensor from detecting approaching of a user by stopping operation of the sensor when the user turns on an electric device manually while entering an object area, such as a toilet, and which can automatically turn off the electric device by operation of the sensor when the user gets out of the object area or make the user stop operation of the electric device manually by outputting pre-determined sound.

#In recent years, in Korea, The amount of energy used for illumination reaches 18% of the total electric energy consumption amount, and is being greatly increased every year according to the highly-graded life environment. Nowadays, according to the worldwide tendency of conservation of earth environment, attempts for minimizing environmental pollution by efficiently using electric power through improvement of energy efficiency in the illumination field and through energy saving have been made very positively.

#In general, for example, the most universally used electric devices are incandescent lamps, fluorescent lamps, and so on.

#Further objects and advantages of the invention can be more fully understood from the following detailed description taken in conjunction with the accompanying drawings in which:

#FIG. 1 is a block diagram of a power saving switch according to a preferred embodiment of the present invention;

#FIG. 2 is a front view of a switch box provided with an input/output unit of FIG. 1;

#The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

#FIG. 1 is a block diagram of a power saving switch 10 according to the present invention, and FIG. 2 is a front view of a switch box 102 provided with an input/output unit 100 of FIG. 1.

#Referring to FIGS. 1 and 2, the power saving switch includes the input/output unit 100, an electric device 200 electrically connected with control means 110, which is included in the input/output unit 100, and a sensor 300 electrically connected with the control means 110.
