可動接点ばね１４が弾接されている。 Examples will be described below using figures. Figures 1 and 2 show an embodiment of the present invention, in which 1 is an L-shaped first yoke, 2 is a permanent magnet magnetized in the vertical direction, and 3 is an L-shaped second yoke. There is a permanent magnet 2 on the horizontal piece 1a of the first yoke 1.
The horizontal piece 3a of the second yoke 3 is placed through the vertical piece 1b of the first yoke 1, and the vertical piece 3b of the second yoke 3 is made to protrude outward through the rectangular through hole 4 provided in the vertical piece 1b of the first yoke 1. The lower end of an iron core 6 inserted and fixed into the excitation coil 5 is fixed to the horizontal piece 3a of the second yoke 3. In the embodiment, the narrow diameter portion 6a provided at the lower end of the iron core 6 is connected to the first yoke 1, the permanent magnet 2, the second yoke 3, and the device stand 7.
Through holes 8, 9, 10, 11 respectively provided in
The narrow diameter portion 6a is made to protrude from the lower surface of the container stand 7 through the
By riveting the tip end portion 6a', both yokes 1, 3, permanent magnet 2, and excitation coil 5 are fixed to the base 7, and the assembly process is greatly simplified. Note that the through holes 8 and 9 of the permanent magnet 2 and the first yoke 1 have a larger diameter than the narrow diameter portion 6a. In this embodiment, since the permanent magnet 2 disposed between the yokes 1 and 3 is assembled without using adhesive,
The permanent magnet 2 is held between the first and second yokes 1 and 3 made of soft magnetic material, and the base 7 and the coil made of synthetic resin do not have any adverse effects on the contact parts due to the gas generated from the adhesive. Since the frame 5a is used to fix the magnet, the impact force applied to the permanent magnet 2 when the magnet is fixed by the soft magnetic material and synthetic resin with low hardness is reduced.
The permanent magnet 2 does not break during assembly. Furthermore, during assembly, both yokes 1 and 3 can be temporarily fixed by the magnetic attraction force of the permanent magnet 2, making assembly easier. Reference numeral 12 denotes an inverted L-shaped armature made of a magnetic material, and the armature 12 has a central bent portion 12c pivotally supported on the upper end of the vertical piece 1a of the first yoke 1. The vertical piece 12b of the armature 12 is arranged to face the outer surface of the vertical piece 3b of the second yoke 3, and the horizontal piece 12a is arranged to face the upper end surface of the iron core 6 of the exciting coil 5. . 13 is a fixed contact terminal having a fixed contact 13a; 14 is a movable contact spring having a movable contact 14a; 15 is a card for driving the movable contact spring 14; the armature 12 is biased by the movable contact spring 14; In this case, the movable contact spring 14 is in elastic contact with the vertical piece 12b of the armature 12 so that the tip of the horizontal piece 12a of the armature 12 is biased upward.

になつている。 In the embodiment, when the vertical piece 12b of the armature 12 is in contact with the outer surface of the vertical piece 3b of the second yoke 3 and the movable contact 14a and the fixed contact 13a are separated, that is, when the reset state is established, The magnetic circuit is a closed loop of the first yoke 1 → permanent magnet 2 second yoke 3 → armature 12 → first yoke 1. In this closed loop, a magnetic flux path is formed by the permanent magnet 2 and the armature 12
is latched in a reset state. On the other hand, when the horizontal piece 12a of the armature 12 is in contact with the upper end surface of the iron core 6 of the exciting coil 5, and the movable contact 14a and the fixed contact 13a are in elastic contact, that is, in the set state, the magnetic circuit is connected to the iron core 6→ 1st yoke 1
→Permanent magnet 2 → Second yoke 3 → Armature 12
→The iron core 6 becomes a closed loop, and the armature 12 is latched into a set state by the permanent magnet 2.
