Delay switch module

A delay switch module, comprising:

• a delay switch, which is connected in parallel to a load switch (SW) that is accessed between a commercial alternating current power source (AC) and an electric device (10) and turns the electrical device (10) on/off, is switched on for a delay-off time set from when the load switch (SW) is switched off, while being switched off when the delay-off time has elapsed, so that the operation of the electric device (10) is automatically stopped when the delay-off time has elapsed after switching off the load switch (SW);
• and
• a control unit (120), which senses on-off switching of the load switch (SW) if there is an on-off switching operation of the load switch (SW) after switching off the load switch (SW), and controls the operation-off of the delay switch (110) so that the set delay-off time of the delay switch (110) is changed according to the on-off switching operation of the load switch (SW).
