To provide a current direction switching circuit which reduces power consumption, avoiding a wasteful current other than the current required for load flowing.

One end of load 3 is connected to ground, and the other end of the load 3 is connected to the junction between one end of the first switch SW1 and one end of the second switch SW2, and the other end of the first switch SW1 is connected to a positive current source 1, and the other end of the second switch is connected to a negative current source 2. The direction of the current flowing to the load 3 is switched by turning on either of the first and second switches SW1 and 2.
