Abstract
Abstract An easily disassemblable separate ceiling fan switch box structure which makes the upper cover and the lower housing body of the switch box locked and joined. Its upper cover can join to a wire distribution receptacle which connects to the wires of the elements of the switch device. The said wire distribution receptacle can couple with the wire distribution receptacle connected to the wires of the ceiling fan motor and then a fixing sleeve ring fixes and joins them. Further an annular or frame-shaped PC board can also be installed in the inner part of the lower housing body to allow the said elements and their wire distribution receptacle to be directly installed thereon, hereby making the ceiling fan switch box structure simplified and compact for convenient disassembly or assembly.
