Abstract: The present invention relates to a delay switch module comprising: a delay switch (110), which is connected in parallel to a load switch (SW), is switched on during a set delay-off-time from when the load switch (SW) is switched off, and is switched off when the delay-off-time has elapsed, so that an operation stops when the delay-off-time has elapsed after the load switch (SW) is switched off; and a control unit (120) for sensing on/off switching of the load switch (SW) if there is an on/off switching operation of the load switch (SW) after the load switch (SW) is switched off, and controlling an operation-off of the delay switch (110) so that the set delay-off-time of the delay switch (110) changes according to the on/off switching operation of the load switch (SW).

Abstract: The present invention comprises: a TRIAC (110) operated by TRIAC driving current input to a gate terminal (g); a bridge diode (120) for full-wave rectifying current which is output from the gate terminal (g) of the TRIAC (110) or input to the gate terminal (g) of the TRIAC (110); a TRIAC triggering unit (130) which operates the TRIAC (110) by receiving current (I) output from the bridge diode (120) as an input and outputting a TRIAC driving current (I1) for turning on the TRIAC (110) to the gate terminal (g) of the TRIAC (110); and a latch circuit unit (140) for outputting latch current which is in a latch-on state and has a smaller value than critical current (Ith) of the TRIAC (110) to the gate terminal (g) of the TRIAC (110).
