With the two-wire wiring device 10 that performs phase control, it is difficult to secure both the load power required for the lighting device 21 and the operating power required for the wiring device 10. Therefore, in the present embodiment, the storage circuit of the control power supply 13 uses a triac or a pair of thyristors as the phase control switch 14 to control the turn-on timing of the phase control switch 14 before the zero-cross timing of the AC voltage Va1. The electric power received via the electric path W0 is stored for a predetermined period. Further, the power storage circuit of the control power supply 13 uses a pair of FETs or a pair of bipolar transistors as the phase control switch 14 to control the turn-off timing of the phase control switch 14 (reverse phase control), and to control the AC voltage Va1. The electric power received via the electric path W0 is stored in a predetermined period after the zero-cross timing.

Since the control power supply 13 described above generates the DC control voltage Vs1 (operating power) from the stored power of the storage circuit, it is possible to stabilize the control voltage Vs1 and suppress an unexpected reset due to a decrease in the control voltage Vs1.
