<P>PROBLEM TO BE SOLVED: To provide an electrical load control device that controls the operation timing of each of multiple electrical apparatuses and stably operates a power supply device. <P>SOLUTION: The electrical load control device includes: a timing generator that periodically generates a timing signal for controlling the timing of power supply; a detection circuit that compares an input timing signal with a reference level signal set for identifying each electrical apparatus and, when they are coincident with each other, outputs a coincidence signal; a conduction switch brought into conduction in accordance with the coincidence signal; and an operation switch for turning on/off each of the electrical apparatuses. With respect to an electrical apparatus the operation switch of which is turned on by an operator among the electrical apparatuses, the conduction switch is brought into conduction with timing with which a detection circuit provided in the electrical apparatus outputs a coincidence signal and it is supplied with power. <P>COPYRIGHT: (C)2011,JPO&INPIT |
