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.
