特徴とする電圧切り換え回路。 A plurality of constant voltage elements having different ratings are connected in parallel to one terminal section, and each of them except the constant voltage element for outputting a steady voltage is provided with a switching element, and the constant voltage Normally, a constant voltage is output from the terminal section due to the function of a constant voltage element for outputting the voltage, and when one of the switching elements receives a corresponding external signal, it operates and this is set. When the constant voltage element is turned on, the rated voltage of the constant voltage element is output. When a separately incorporated switch is closed, a voltage different from the constant voltage and the rated voltage is output. and a voltage switching circuit configured to output a steady voltage again when the conduction of the constant voltage element is released and the switch is opened, wherein the switching element is activated by the external signal. 1. A voltage switching circuit comprising a thyristor that conducts and shuts off by closing the switch.
