ABSTRACT OF THE DISCLOSURE An Operation Program-Presetting System comprising twelve program data-supplying switches arranged in the same order as the time-indicating notations on a clock dial with means for generating a unique coded signal corresponding to the data- supplying switch operated. The coded signals given forth successively by the sequential operation of the switches are separated into time data and control data and stored in sets containing both time and control data. The time data represents the "hour" and "five-minute" units corresponding to the time indicating notations on a clock dial, and the control data instructs the operation of external appliances. A time comparator compares the stored time data with a current time signal and, upon coincidence, a coincidence signal causes external appliances to be operated in accordance with the control data included in the set having the coincident time data. This system enables a large number of programs to be preset with simple operations.
