<p>A timer system includes a power switch (4) operable to power circuit closing and opening conditions, timing means (26) for identifying various timing segments over a 24-hour period and marker storage means (21) having respective power turn on and off marker storage locations assigned to the time intervals encompassing a 24-hour period. An on-off push button (28) or other on-off control operates the power switch (4) and may act as an aid in setting the markers in the storage means. The timer system may also include a rotatable present time setting dial (28), also adjustable to different positions representing the different time intervals, and a manually operable timer on-off setting member (19). For real time programming, control means (12) respond to normal operation of the on-off control during a first24-hour period, initially to set said markers in the storage locations. For fast programming, the control means (12) responds to the successive advancement of time set dial (2(Alpha)) from a present time setting through said various positions and the selective operation of the pushbutton or other on-off control (15) to set the markers in the storage locations assigned to the time interval involved, which markers automatically control the operation of the power switch (4) when the timer on-offsetting member is in its timer-on position, except when overridden by operation of the on-off control (15). </p> |
