Abstract: A method and device using a single-throw switch for controlling the revolving speed of the ceiling fan and light assembly and the light intensity of its lamps. The method obtains a 60 Hz square wave of cycle 16.67 ms from a typical alternating current power supplied from an electric power company and provides a working direct current voltage to a microprocessor through a direct current power supply circuit. When power is turned off and on (a switching cycle) by the single-throw switch, the microprocessor calculates the interrupting time during each switching cycle and regulates the revolving speed of the ceiling fan or the light intensity of the lamps based on the calculated result.
