To provide a circuit for switching over direction of current, which is capable of preventing an unwanted current other than a necessary current from flowing through a load and of reducing power consumption. A load is connected at one end to the ground and is connected at the other end to the connection between one end of a first switch and one end of a second switch. The first switch is connected at the other end to a positive current source and the second switch is connected at the other end to a negative current source. A direction in which a current flows through the load is changed over by selectively turning on any one of the first and second switches. |
