Abstract

PURPOSE: To make it possible to manually turn off a power source during the operation of a timer, even if a main switch is connected in parallel with a timer relay, by a reset switch is added to a program timer.
CONSTITUTION: Upon detection of the fact that a reset switch 61 is depressed, a reset circuit 6 generates pulsating voltages in a signal line 62, and the voltages are fed to an OR circuit 7 and a signal line 71 to the R terminal of an FF 33. As a result, this FF 33 reverses its condition so that a timer relay 4 is brought into its inconductive condition through a relay drive circuit 41 to turn off a TV power source 5. As a result, even if the main switch and the timer relay are connected in parallel so that the timer is operating, the power source can be instantly turned off if the reset switch is manually depressed.
