WALL SWITCH DETECTING HUMAN BODY

摘要

PURPOSE: A wall switch detecting a human body is provided to perform an on/off operation of a switch by detecting a capacitance or resistance value to generate a switching signal. CONSTITUTION: In case that a human body contacts or approaches to a dielectric plate, a capacitance detecting unit(20) detects a changed capacitance to convert the detected capacitance into an electric on/off signal. A switch unit(40) is connected to a power line for turning on and off a wall switch to perform a switching operation of power supplying. A switch control unit(30) receives a signal from the capacitance detecting unit(20) to control the operation of the switch unit(40). A rectifying unit is connected to the power line to supply a direct current power to the capacitance detecting unit(20) and the switch control unit(30).
