1. the wind speed stepping indicating circuit of an electric fan comprises an one pole multi-position switch, and its public terminal is access to a utmost point of power supply, and every terminal is access to each the speed governing tap of fan motor winding respectively;

  • It is characterized in that;

    each is access to each the speed governing tap of fan motor winding through a low impedance circuit the every terminal of described switch, this low impedance circuit is the parallel circuit of many branch roads, and wherein branch road is that a light emitting diode or a light emitting diode and other element are in series;

    Described Low ESR be the corresponding speed governing tap of described fan motor winding impedance loop 5% in.
