Abstract

PURPOSE:To set an output terminal at an ON level just with a make operation of a power supply switch by providing a switching circuit which works when its output is set at an OFF level to a control terminal of a power supply control circuit. CONSTITUTION:A rectified output 5 is supplied to a power supply control circuit 6 containing a power supply memory from an AC power supply 1 via a power supply transformer 2, a power supply switch 3 and a rectifier circuit 4. Then a desired output level is secured at an output terminal 7. In this case, a swithing circuit 10 is connected to a control terminal 8 of the circuit 6. The circuit 10 works only when the terminal 7 is set at an OFF level when the output 5 is impressed. Then the terminal 7 is changed to an ON level. Thus the switch 3 is opened and then applied again while the terminal 7 is kept in an ON state. As a result, an ON state is delivered to the terminal 7. Thus transistor 10a and 10b are kept cut off with the terminal 8 kept open respectively. Then the terminal 7 is kept ON as it is.
