A control system for operating at least two electrical appliances, such as a combination ceiling fan and light assembly, from a remotely located multi-position manually operated switch assembly. The system responds to a series of different control signals actuated by the different switch positions to switch either one of the appliances on or off, to control the intensity of the light or the speed of the fan, or to initiate any one of a series of pre-programmed sequences of operations of the appliances.

A system for remotely controlling at least two electrical appliances powered by an AC power source, comprising: a series of manually operable switches; control signal generating means responsive to actuation of the switches for providing a firing delay in the AC sine wave after a zero crossing; each switch corresponding to a delay signal of predetermined length in a predetermined polarity half of the AC signal distinct from all the other switch signals; delay signal detecting means connected to said generating means for detecting said delay signals and producing control pulses in response to said delay signals; said detecting means comprising first control means for detecting the polarity of the delayed half of an input AC signal and producing an output polarity control signal, and second control means for producing a control signal pulse of length dependent on the half cycle length of the input AC signal, each control signal pulse produced by said delay signals having a predetermined length shorter than the standard AC half cycle pulse length; and programmable control means for controlling operation of said electrical appliances in response to stored program instructions and detection of said polarity control signals and control signal pulse length; said program instructions including means for associating each shortened control signal pulse length of each polarity with a predetermined control function, said control functions including means for switching each appliance on and off, and means for initiating a series of pre-programmed sequences of operations of said appliances.
