特徴とする切替装置。 A driving piece is disposed passing through the internal space of the cylindrical electromagnetic coil, and the driving piece is movable in parallel within the internal space in a direction orthogonal to the longitudinal direction of the cylindrical electromagnetic coil by means of a guide part. A magnetic field is formed by a permanent magnet with N and S poles facing one end of the drive piece in the moving direction of the drive piece, and the magnetic field formed at the other end is the same as the magnetic field of the one end. are in opposite directions, and the N-pole side and the S-pole side of each end are connected via a magnetic path member arranged parallel to the drive piece, and 1
A static magnetic field is formed, and by switching the direction of supplying current to the electromagnetic coil, the direction of the magnetic field at the end of the drive piece is changed, and the drive piece is configured to operate in the direction of the magnetic field by the permanent magnet. A switching device characterized by:
