<p>PURPOSE:To control surely turn-on/turn-off of a power source by supplying simultaneously a power source turn-on indicating signal fed from a power source controlling device supplied through a signal line to each device to be fed, and providing turn-on sections that turn on power source to the devices fed to be at different timing. CONSTITUTION:Power source turn-on/turn-off indicating signal lines 14 from a power source controlling device 1 are connected to each devices to be fed Ti (i=1, 2...). The signals are used as starting signals of a timer circuit 23 through a gate 22. In the timer circuit 23, different counting times are fed to devices Ti beforehand by setting switches SW. Time up signal of the circuit 23 used as a power source turn-on/turn-off signal to a power source 24. A relay RL for closing a switch 26-i is driven 25 by the action of the power source section 24. By closing the switch 26-i, a lamp 12-i provided in the device 1 is lit up.</p> |
