The above-mentioned "attracting when the first magnet 22 and the third magnet 32 are opposite each other" means that: when the first magnet 22 and the third magnet 32 are opposite, the magnetic fields of the two magnets are the same, for example, the first magnet 22 has an upward N pole and a downward S pole, the third magnet 32 also has an upward N pole and a downward S pole, and when the two magnets are opposite, the S pole of the first magnet 22 faces the N pole of the third magnet 32, so that the two magnets attract each other; the above-mentioned "the second magnet 23 and the third magnet 32 repel each other when they are opposite to each other" means that: when the second magnet 23 and the third magnet 32 are opposite to each other, for example, the second magnet 23 is opposite to the third magnet 32 in that the S pole is upward and the N pole is downward, and the third magnet 32 is opposite to the first magnet, the S pole is downward, and when the two magnets are opposite to each other, the N pole of the second magnet 23 faces the N pole of the third magnet 32, so that the two magnets repel each other.
The above-mentioned "the operating body 2 is rotated around the axis L so that the first magnet 22 or the second magnet 23 is opposed to the third magnet 32" means that: when the operating body 2 is rotated about the axis L relative to the housing 1, the state in which the first magnet 22 is opposed to the third magnet 32 and the state in which the second magnet 23 is opposed to the third magnet 32 can be switched to move the movable assembly 3 between the first position and the second position.
The above-mentioned "the first position is closer to the knob 21 than the second position" means that: the vertical distance from the knob 21 when the movable body 31 is in the first position is smaller than the vertical distance from the knob 21 when the movable body 31 is in the second position.
