Abstract:
1. A switching apparatus comprising: a contact point section including a first contact point; an actuator including a first piezoelectric film that expands and contract according to a first drive voltage and a second piezoelectric film that is provided in parallel with the first piezoelectric film and expands and contract according to a second drive voltage, the actuator moving a second contact point to contact or move away from the first contact point according to the contraction and expansion of the first piezoelectric film and the second piezoelectric film; and a control section that controls the first drive voltage and the second drive voltage, wherein when causing the first contact point and the second contact point to contact each other, the control section applies the first drive voltage causing the first piezoelectric film to contract to the first piezoelectric film, such that the actuator bends toward the first piezoelectric film, and when switching the first contact point and the second contact point from a contact state to a separated state, the control section stops supplying the first drive voltage and applies the second drive voltage causing the second piezoelectric film to contract to the second piezoelectric film, such that the actuator is biased to return.
