(54) MAGNETIC CONTROL SWITCHING ELEMENT (57) The invention relates to automation and may find application in automatic control, monitoring, measurement and communication systems. The aim of the invention is to expand operational capabilities by providing additional switching of the light signal. In a sealed container 1 made of a solid dielectric, optical fibers 2. 3 and ferromagnetic plates 4, 5 are cantilevered. Ila axis 6. working on the cap, the Z-shaped ferromagnetic plate 7. 1 ill. Is rigidly fixed.

The invention relates to automation and can find application in systems of automatic control, monitoring, measurement and communication.

The purpose of the invention is the expansion of functionality by providing additional switching of the light signal.

The drawing shows a magnetically controlled switching element, a longitudinal section.

The switching element contains a sealed container 1 made of a solid dielectric, and optical fibers 2 and 3 with polished ends, mounted fixedly on the same axis with a gap and opposite one another. At the opposite ends of the cylinder, ferromagnetic plates 4 and 5 are cantilevered, the protruding ends of which act as terminals for connecting an external circuit. In the center of the cylinder on the axis 6 there is a Z-shaped ferromagnetic plate acting as a shutter, so that its smaller sections are located in the clearance zones between the fibers. The free ends of the plates 4 and 5 are located above a large section (nsd a large section) of the plate 7 with a gap of 100-200 μm with overlap.

The contact zones of the plates 4, 5 and 7 have a special coating, resistant to erosion and with low electrical resistance.

The switching element is working. in the following way.

In the absence of a control magnetic field, the opaque curtain 7 closes the light flux between the optical fibers 2 and 3 (the state is' Off), while the contacts of the elements 4 and 5 are open.

Under the influence of an external magnetic field, the ferromagnetic plate 7 deviates all the way into the plates 4 and 5, while the path opens with the light flux (the On state) and the contacts of the elements 4, 5, and 7 are closed.

The case (cylinder) of the element can be made detachable, made of 5 d? S parts. In this case, the optical fibers and ferromagnetic plates are installed in the holes, which are formed by grooves made one opposite the other in both parts of the housing.

Axis 6 is rigidly fixed in the central holes of the housing and works on torsion.

The sealing of the switching element is carried out, for example, using adhesive K-9.
