The present invention relates to a rotary switch power supply apparatus. The rotary switch power supply apparatus sets an accurate current value through a rotary switch, in comparison with a variable resistive product, even when a current value measuring instrument does not exist, thereby generating a current value to be calculated without additional equipment; reducing a burden in terms of costs in comparison with a fixed constant current product; reducing costs and time for developments of a derivative product or series if a current value is set in advance by setting a resistance value in preparation for alterations to specifications of a load; and minimizing inconvenience caused by a kc reauthorization process when the power supply apparatus is altered by the alteration to the specifications of the load. |
