  • Patent number: 4896083
    Abstract: A control circuit is provided preferably for use with a ceiling fan and lamp unit having operating power supplied thereto by way of a wall switch and which allows successive operation of the wall switch to selectively energize the fan and lamp thereby avoiding the need for a separate pull chain. The preferred control circuit is electrically interposed between the wall switch and the fan and lamp unit and includes a sensing circuit for sensing successive applications of operating power from the wall switch and an activating circuit responsive to the sensing circuit for selectively activating the fan and lamp in a plurality of output combinations in predetermined sequence upon successive wall switch operations. In preferred use, the wall switch is successively operated to the on position until the desired load combination is achieved.
