Abstract: Disclosed is a control circuit for dual function electrical appliances such as multi-speed ceiling fans having light fixtures. The circuit uses the hot line of a cable to carry power to the appliance and to carry two distanct signals for remote control thereof. A two button switch intercepts the hot line at a convenient position and provides means for selectively half-wave rectifying AC current therein. Two independent signals, positive and negative pulses, are produced at the two button switch and transmitted to the appliance through the hot line of the cable. These signals are received in control circuitry within the appliance housing which senses the pulses, identifies whether each pulse is positive or negative and counts the number of pulses in both the positive and negative phase caused by toggling the two button switch.

Abstract: A circuit for controlling a ceiling-type fan includes a switch or relay for controlling the fan, connectable to the fan. A logic circuit produces an output signal for controlling the switch or relay from an input signal generated by momentarily interrupting the power applied to an input to the logic circuit. A diode and capacitor isolate the power supply connections of the circuit to maintain the supply voltage during the momentary power interruptions.In one embodiment the control circuit controls the on-and-off switching of the fan, as well as its speed, together with on-and-off switching of a light associated with the fan. In one embodiment the forward and reverse directions of the fan are controlled as well.
