A three-in-one control device for a ceiling fan includes a signal receiving module, which is able to receive segmented controlled signals, stepless controlled signals and wireless controlled signals respectively, for transmitting controlled signals to a micro computer control unit to process, analyze and code them. Then, the processed signals are transmitted to a driving unit to drive the blades of the ceiling fan to rotate. Therefore, when a control switch is replaced with another type, it is unnecessary to change the control device but just connect it to a corresponding control module, able to save manufacturing cost.
