    摘要: The device includes a permanent magnet for attracting a movable iron armature. A pair of elongated rectilinear magnetic bodies have planar pole faces at one end facing the iron armature, and the permanent magnet is sandwiched between these two magnetic members intermediate their ends, with the permanent magnet extending perpendicularly to the magnetic members. Respective magnetizing windings embrace each magnetic member between the permanent magnet and the pole faces of the members, to produce a magnetic flux in the magnetic members opposing the flux provided by the permanent magnet so as to release the iron armature. In one embodiment of the invention, the other ends of the members, projecting beyond the permanent magnet, are angled to face each other to provide an air gap therebetween. In a second embodiment of the invention, the magnetic members or yokes have respective second windings thereon, beyond the permanent magnet, and the ends of these yokes, beyond the second windings, are formed with planar pole faces for operative association with a second iron armature. Both iron armatures are spring biased to disengage the magnetic yokes or members. As the permanent magnet engages the yokes intermediate their ends, the magnetic flux path due to the magnetizing windings does not include the permanent magnet and therefore an effective armature releasing magnetic flux can be provided with only a relatively small current supplied to the magnetizing windings.

    摘要: A wavelength selection switch (1) equipped with: an input/output unit (10) having multiple input/output ports that input/output signal light; a light-collecting mirror (14) arranged in the light path of the signal light from the input/output unit; a dispersion element (13) having a dispersion part and a non-dispersion part that does not have a dispersion effect; and multiple deflection elements (16) arranged in the direction in which the signal light is dispersed. The light-collecting mirror (14) causes the signal light from the input/output unit (10) to enter the dispersion part of the dispersion element (13), and the light that is dispersed by the dispersion element (13) is collected in the deflection elements (16) through the non-dispersion part of the dispersion element (13). Furthermore, the deflection elements (16) deflect the collected light such that the light is emitted from a prescribed input/output port of the multiple input/output ports.
