Abstract
PURPOSE: To make it possible to use a controlled circuit as the electric power economizing circuit in the temperature control device of an electric blanket and so on, by controlling the operation of the switching element of the controlled circuit by the self-holding function and the operation of a timing device.
CONSTITUTION: Control circuit 4 turns on and off thyristor 3 to supply electricity to load 2 to be a set value set by variable resistor 5. Timing device 8 starts the operation by closure of push-in switch 9 and turns on transistors 6 and 29 for a fixed time. At this time, control circuit operates with the set value as the maximum value. Transistor 21 is held in the turning-off state by switch 9. When the timing signal is broken, transistor 30 is always turned on not to supply electricity to load 2 because transistor 29 is turned off. Next, transistor 27 is turned on to release self- holding by the second timing signal, and control circuit 4 performs the control operation corresponding to the set value.
