PURPOSE: A switch control device is provided to prevent electricity to be wasted by automatically turning off a switch without the manipulation of a user when a predetermined period of time passes. CONSTITUTION: A switch(110) electrically connects or disconnects a power part(10) with a load part(20). A charging part(130) is charged with voltage applied to the both ends of the switch. A solenoid(140) operates with power charged at the charging part. A control part(150) charges the charging part when switch is in an off state. A rectifying circuit(120) is connected electrically between the switch and the charging part.
