PROBLEM TO BE SOLVED: To provide a drive mechanism that can maintain a switching condition without power consumption. SOLUTION: This device has a movable electrode 12 which has a first electric contact point 20 and a fixed electrode 28 which has a second electric contact point 18. It is composed of a latching magnetic material 14 arranged on one of the movable electrode and the fixed electrode, electric conductors 10 arranged separately from the latching magnetic material, and a second magnetic material 16 arranged on the other of the movable electrode and the fixed electrode separately from the latching magnetic material. By exposing the latching magnetic material 14 to the exterior magnetic field formed by feeding a current into the electric conductors 10, a change in the magnetization direction of the latching magnetic material is caused, and the changed magnetization direction is maintained in the latching magnetic material 14 even after that its exposure to the formed exterior magnetic field has ended. |
