1. A power saving switch comprising:
- a first moving body sensor arranged on an entrance of a specific object space or on a position adjacent to the entrance;
a second moving body sensor arranged in the inward direction of the specific object space from the first moving body sensor; and
control means electrically connected with the first and second moving body sensors, wherein the control means automatically turns on an electric device installed inside the specific object space when a detection signal of the second moving body sensor is received after a detection signal of the first moving body sensor is received, and wherein the control means automatically turns off the electric device when the detection signal of the first moving body sensor is received after the detection signal of the second moving body sensor is received, andwherein the control means stops operation of the first and second moving body sensors for a predetermined time period after automatically turning on the electric device installed inside the specific object space when the detection signal of the second moving body sensor is received after the detection signal of the first moving body sensor is received, and wherein the control means stops operation of the first and second moving body sensors for a predetermined time period after automatically turning off the electric device installed inside the specific object space when the detection signal of the first moving body sensor is received after the detection signal of the second moving body sensor is received.

Abstract
A power saving switch which can turn on an electric device manually by manipulation of an automatic switch button or a manual switch button by a user, and simultaneously, stop operation of a sensor for a predetermined time period in order for the sensor to fail detection of an entering of the user into an object area, and which can turn off the electric device automatically or output predetermined sound so as to make the user turn off the electric device manually when the user goes out of the object area.

4. A method for controlling a power saving switch comprising the steps of:
-
i) automatically turning on an electric device installed inside a specific object space when a detection signal of a second moving body sensor arranged in the inward direction of the specific object space from a first moving body sensor is received after a detection signal of the first moving body sensor arranged on an entrance of the specific object space or on a position adjacent to the entrance is received; ii) automatically turning off the electric device installed inside the specific object space when the detection signal of the first moving body sensor is received after the detection signal of the second moving body sensor is received; and iii) stopping operation of the first and second moving body sensors for a predetermined time period after the i) step of automatically turning on the electric device and after the ii) step of automatically turning off the electric device.
