回路。It has a circuit that delays the rise time of the power supply voltage, divides the voltage passed through this circuit by a voltage divider circuit, applies this as a control voltage to the control transistor, and responds to the low or high voltage applied to the voltage divider circuit. A switch circuit characterized in that the output transistor is made conductive or open rather than the control transistor is made conductive or conductive, and the switching operation is performed by the output of the output transistor.
