Abstract

PURPOSE: To surely short the neon tube of a voltage detecting circuit at the power source OFF and prevent the photoelectric charge of a main capacitor from being discharged by providing a switch which interlocks to turning-on of power source.
CONSTITUTION: A voltage detecting circuit series-connected with a resistor R1 and neon tube N1 is parallel-connected to a light-emitting main capacitor C1 and one end of a switch S2 interlocking to a power source switch is connected to the point of connection of the resistance R1 and neon tube N1, so that when the power source switch goes OFF, the neon tube N1 is shorted. Thereby, the neon tube may be surely put out even under high humidity.
