Abstract

Invention m. used in systems of automatic control, monitoring, measurement and communication, and allows to increase the vibration resistance of the device. In the pressurized container 1, two light guides 2 are mounted in a cantilever and opposite each other. In one end of the canister 1, a ferromagnetic L-shaped shutter is fixed in a cantilever. 3, the protruding end of which is placed in the gap between the polished ends of the light guides. The impact of an external magnetic field leads to the deviation of the shutter 3 up to the stop in the ferromagnetic plate 4, installed in the opposite end of the cylinder 1. At the same time, the luminous flux passes freely from one light guide to another. 1 ILO

Description

cl

The invention relates to KJB automatics, radio, electrical, and computer technology and can be used in automatic control, monitoring, measurement, and communication systems.

The purpose of the invention is to increase vibration resistance.

The drawing shows a magneto-equalized switching element (longitudinal section), a closing path dp of a light signal and a closing path for an electric signal under the influence of an external magnetic field.

The switching element contains a sealed dielectric housing 1, light guides 2 with polished ends, installed unsupported on the same axis with a gap and opposite to each other. A ferromagnetic G-shaped curtain 3 is fixed in the housing of the housing, the protruding end of which serves as a terminal for connecting an external electrical circuit.

A ferromagnetic plate 4 is fixed at the opposite end of the cylinder, the protruding end of which is hollow and the role of the second viewport for the elec- trical circuit. A smaller section G - with a curtain is inserted into the gap between

A magnetically controlled switching element containing a sealed balloon, two fibers with ground ends mounted cantilever and opposite each other inside the balloon in its opposite ends, and a l-shaped shutter reinforced with a cantilever in one of the ends of the sealed balloon so that its smaller section is located the gap between the ends of the light guides, about t-l and h y and with the fact that, in order to increase the vibration resistance, in the opposite end of the sealed balloon an additional one is installed on the ferromagnetic plate, wherein

The contact zones of the shutter 3 and the plates have a special coating that is resistant to erosion and with low electrical resistance

In the absence of a control magnetic field, an opaque shutter blocks the luminous flux (Off states), while contacts 3 and 4 are open. Under the influence of an external magnetic field, the ferromagnetic curtain deflects against the plate 4, and the light flux opens (On state) and contacts 3 and 4 are closed,
