PROBLEM TO BE SOLVED: To turn on or off the power sources of a main electronic appliance and auxiliary electronic appliances through one time operation by turning on/off the power sources of the auxiliary appliances, in accordance with the turning on/off of the power source of the main appliance by turning on/off the power supply to the auxiliary appliances by opening/closing a relay means. SOLUTION: When a power switch is turned off, a current detecting circuit 5 demagnetizes a relay circuit 6 at the current value set by means of a current setting switch 7, and a traveling contact D of the circuit 6 travels and turns off the power line of an AC power terminal 1 through which electricity is supplied to the terminals 9, 10, and (n) of auxiliary electronic appliances. Moreover, when the power switch is turned on, the moving contact D of the relay circuit 6 is similarly turned on and the power supply to the auxiliary electronic appliances is turned on. Therefore, the power supply to a main electronic appliance and the auxiliary electronic appliances can be turned on or off through one time operation, and the labor and time required for turning off or on the power supply to the auxiliary electronic appliances can be eliminated. |
