する溝を有するラブ子ベースと。When the trip core I21) is provided below the latch (181), the self-demagnetizing switch (29) and the axis q (g), which is the center of rotation of the latch mark, are close to each other, and the auxiliary crossbar (3)
'The displacement of ZJ is large and there are drawbacks. Also, the axis (
If 19) is provided on the lower side, the rotation radius of the latch (181) will become smaller, and the inclination of the tripping core 121 will increase, and the reliability of the engagement between the latch αQ and the latch receiver (1) will decrease. If the shaft α9 is placed upward, the latch (18) and latch base 07J will naturally become larger, making the device larger. In order to create a large displacement of the operating Iida at the top, a self-demagnetizing switch (29) is arranged opposite to the lanotibe fixed iron core, and is rotatably attached to the movable iron core that is operated by the current applied to the closing coil. A lever, a latch receiver rotatably attached to one end of the lever, and a love base having a groove in which the latch receiver slidably engages.
