Claim 1:
2. The electronic apparatus according to claim 1, wherein
one of the fixed magnet and the movable magnet has at least three magnetic poles of both N-poles and S-poles, the N-poles and the S-poles being alternately disposed along the moving direction of the slider and also being disposed on a face opposing the other magnet,
the other of the fixed magnet and the movable magnet has two fewer magnetic poles than a number of the magnetic poles of the one magnet, the two fewer magnetic poles being disposed in the moving direction and also being disposed on another face opposing the one magnet, and
the movable magnet and the fixed magnet are disposed so that magnetic poles on the movable and fixed magnets of opposite polarity face each other when the slider is in the first position and the second position, and magnetic poles on the movable and fixed magnets of the same polarity face each other when the slider is located between the first position and the second position.
