<p>PROBLEM TO BE SOLVED: To provide a load control device with which plural load circuits can be connected, and further, in which confirmation of non-connection and erroneous connection of the respective load circuits is possible. SOLUTION: Relays Ry1 to Ry4 respectively makes on/off of load circuits C1 to C4. The on/off of the relays Ry1 to Ry4 is directed by a control treatment part 10 to receive operation input generated at every press-operation of operation switch 11. At the control treatment part 10, a control pattern in which the load circuits C1 to C4 of all the system are turned on at every generation of operation input, and four kinds of control patters in which respective load circuits C1 to C4 are sequentially turned on by every one system in turn are selected in cycles.</p> |
