ABSTRACT:
A system is provided for automatically switching an electric circuit on and off at certain times of the day, in which those certain times of the day vary throughout the year in accordance with a pattern built into the system and are not intended to be altered by the user. A computer timer provides the time of day and day of the year. A memory is permanently programmed with data that are stored to identify switch-on times and switch-off times for each day. The time of day and day of the year are compared with the switch-on times and switch-off times that are stored in the memory, and a current switching device is operated accordingly to switch an appliance, such as an electric lamp, on and off at the programmed switch-on times and switch-off times, respectively.
