Zusammenfassung:	PURPOSE:To reduce radio wave defect by providing an oscillator in which its oscillation frequency can be switched by a switch. CONSTITUTION:A switching power source is composed of full-wave rectifying set diodes 1 for a commercial power source, a switching transistor(Tr) 2, a high frequency transformer 4, a half-wave rectifying diode 5, a smoothing choke transformer 6 and a capacitor 7. An oscillator in which its oscillation frequency (switching frequency) can be switched by a switch 9 is employed as an oscillator 8. Thus, harmonic wave components can be isolated from a broadcasting radio wave by selecting the oscillation frequency by the switch 9 thereby to reduce the degree of a disturbance.
