Definition of Switching Power Supply

It is just a power supply that uses a switching regulator to convert AC voltage to a DC voltage. Switching power supplies reduce and convert voltage from an AC source, to DC volts for a load.

The word "Switching" only refers to the regulator used in the voltage conversion, it has nothing to do with switching the input or output voltage to different values.

Hope that clears things up for you...
