PURPOSE:To facilitate deciding whether the action state of load is a pattern control or not by detecting the coincidence of the state of an action setting switch of each load and the action state and whether all coincident signals corresponding to pattern operation switches can be obtained or not and displaying them. CONSTITUTION:Pattern control circuits PC1-PCn set an interlocking mode and non-interlocking one through action setting switches Sa-Sc in correspondence to operation switches SWa-SWc. A pattern action display circuit PD detects whether or not coincident detection signals from all coincidence detecting means corresponding to respective pattern operation switches SWa-SWc can be obtained in an NOR circuit NOR. For instance, an output of an exclusive OR circuit EO1 corresponding to the switch SWa of the pattern control circuits PC1- PCn is inputted to the NOR circuit NOR of the display circuit PD corresponding to the switch SWa, and when all outputs of the circuit EO1 become a low level, an output of the NOR circuit NOR rises up to a high level. Then a light-emitting diode LD3 is lit and displays that the action state of the total load 7 is caused by the control of the switch SWa. |
