ABSTRACT:
There is provided a switching circuit including, a semiconductor switching circuit comprising, a transistor, a first electrode of the transistor being connected to an electrical source via a load, a second electrode of the transistor being connected to a standard potential, a driving circuit outputting a signal to a control electrode of the transistor on a basis of a potential in the first electrode of the transistor so as to turn on and off the transistor, the driving circuit turning on when an input voltage applied from an input terminal being a first voltage higher than a threshold voltage of the transistor, the driving circuit turning off when the input voltage being a second voltage lower than the threshold voltage of the transistor.
