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.
