１の正確な揺動動作を保証し得る。 Further, the operation of the above embodiment will be explained. If current is applied in a certain direction to the coil 10 wound around the coil frame 9, the armature 1 will move as shown in FIG.
The other end of 1 is magnetized, for example, to the N pole, and the permanent magnet 18
A magnetic path with the first yoke 13 can be formed through the second yoke 16 that comes into contact with the side of the half of which is magnetized with an N pole on the upper side and an S pole on the lower side. Therefore, the armature 11 is attracted to the magnetic pole portion 17 of the second yoke 16, and the contact spring 8 on the second yoke 16 side is driven. On the other hand, when the coil 10 is energized with a current in the opposite direction, the armature 1 as shown in FIG.
The other end of the permanent magnet 18 is magnetized, for example, to the north pole, and is in contact with the side of the other half of the permanent magnet 18, which is magnetized with the south pole on the upper side and the north pole on the lower side, through another second yoke 16. , a magnetic path with the first yoke 13 can be formed.
Therefore, the armature 11 is connected to the other second yoke 1.
6, and another contact spring 8 on the other second yoke 16 side is driven. In this case, since one end of the armature 11 is directly supported by the pivot wall 14 of the first yoke 13, it is not necessary to accurately space the armature 11 and the first yoke 13 apart. On the other hand, since a magnetic circuit is formed only in one of the pair of second yokes 16, 16 depending on the magnetization direction of the armature 11, the armature 1
1 accurate rocking motion can be guaranteed.
