To provide a two-wire system load control device, which can connect apparatuses such as fluorescent lamps and LED lightings without a limitation by the type of load and the number of connection.
The two-wire system load control device includes: a main switch unit 11 having a triac 11a as a main switch element; an auxiliary switch unit 17 for supplying a gate driving current to a gate electrode of the triac 11a; and an attenuation filter, which is connected between the gate electrode of the triac 11a and the auxiliary switch unit 17, composed of a capacitor 11b and a resistance 11c for attenuating a gate voltage generated by the gate driving current to attenuate the oscillation of a load current by cutting off a high frequency component when the load current is oscillated.
