Claims

[Claims for Utility Model Registration] Two reed switches 1.2 installed in parallel, both of the above.
A biasing magnet 3 that excites one contact piece mA, 2A of the reed switch 1, 2 to the same polarity, and a biasing magnet 3 that is provided corresponding to the biasing magnet 3 and rotates to excite the other contact piece mA, 2A of the reed switches 1, 2. The tangent lB. The reed switch 1.2 is arranged at a relative position shifted by φ degrees with respect to the center of rotation of the rotary magnet 4, and the rotary magnet 4 is provided with a rotating magnet 4 that alternately excites 2B with the NS pole. N and S poles are provided so that the center of the adjacent NS poles is approximately φ degrees, and the magnetic pole area of the larger magnetic pole area among the NS poles of the rotating magnet 4 is at least φ degrees or more, and When the magnetic pole area of 4 faces the other contact piece IB, 2B of both reed switches 1.2, and the magnetic pole of the biasing magnet 3 and the magnetic pole of the rotating magnet 4 are the same polarity, both reed switches 1: 2 Each contact opens,
In order to close the contacts of both reed switches 1 and 2 when the polarities are different, one of the NS poles of the one-turn magnet is provided with a larger magnetic pole area than the other, and the energizing magnet 3 is set so that the contact pieces 1A and 2A are A rotary switch in which a biasing magnet 3 is provided to a reed switch 1.2 so that the magnetic pole can be selected from NS to NS.
