PROBLEM TO BE SOLVED: To provide a load control module which is suitable for an electronic device and is connected with a switch and has an energy accumulation unit, a microprocessor and a pulse control unit. SOLUTION: The energy accumulation unit still outputs reserved voltage for a designated period when the switch is turned off, and also changes a level of an indication signal according to on-off operations of the switch. The microprocessor controls a duty cycle of a modulated signal by control methods which are different inside and outside a fine tuning time according to variation of the level of the indication signal. Thus, the load control module controls the level of control voltage according to conditions of the on-off operations of the switch in order to attain various control functions.
