1. A twenty-four hour repeat cycle home lighting timer system comprising:

  • a lighting device;

    a timer power input terminal;

    a load device-connecting terminal;

    power switch means coupled between said timer power input and load device-connecting terminals;

    means connecting said load device-connecting terminal to said lighting device;

    said power switch being operable to circuit closing and opening conditions which respectively effect coupling and de-coupling of said load device-connecting terminal to and from said lighting device;

    manually operable light turn-on and turn-off means operable successively to light turn-on and turn-off conditions which respectively normally operate said power switch means to said circuit closing and circuit opening conditions;

    manually responsive timer condition setting means settable to at least timer-off and timer-on and reset conditions;

    storage means having respective storage locations assigned to various successive time intervals over a twenty-four hour programming period and in which light turn-on and turn-off markers can be respectively placed or retained;

    synchronous timing and storage location accessing means for continuously synchronously accessing the storage locations containing the markers for the various time intervals involved; and

    control means responsive first to the setting of said setting means from said reset to either said turn-on or turn-off condition and then to the operation of said manually operable light turn-on and turn-off means only during the first twenty-four hour programming period for storing or retaining said turn-on and turn-off markers under control of said accessing means in appropriate storage locations of said storage means only during the first twenty-four hour programming period so that the timer system is programmed to effect automatic control of said lighting device in accordance with the actual normal pattern of operation of said manually operable turn-on and turn-off means only during such period, and means for operating said power switch means in accordance with the synchronously accessed markers in said storage locations of said storage means when said setting means is in said timer-on condition and for preventing control of said power switch means by said marker when said setting means is in said timer-off condition.
