Description

The invention relates to electromechanical switching devices used in electrical engineering, radio engineering, communication technology, optical communication devices.

The purpose of the invention is the switching of the light fluxes.

The drawing shows a multi-contact switching device. The device contains a glass hermetically sealed balloon 1, into the wall of which fixed contacts 2 of magnetically soft material are fixed, which contain fixed leads of optical fibers 3 located along the longitudinal axis of the sealed balloon along which the contact part is made of rod constant manit 4 including a mobile fiber 5, rigidly mounted on the movable axis 6, which is located in the center of the sealed balloon, on the outside of which it is opposite to fixed objects netic contacts are within VAT 7 sources IECI.

The device works as follows,

IN THE INITIAL state, the MDS sources are not energized, the movable magnetic contact is held, in one position against any magnetic fixed contact, in the closed state due to the permanent magnet, which is part of the movable magnetic part, and the magnetic flux r flows through them. In this state, contacts can be held for as long as desired. .

After the supply of pulsed current to the opposite sources 7 VDS, fed in pairs and sequentially, in the solenoid formed

There is an electromagnetic field causing a magnetic flux Φ which is perpendicular to the moving axis, crossed the constant magnetic field

magnet 4, interacts with it. Since the magnetic flux formed in the solenoid, caused by the current pulse in the 7 MDS sources, is significantly greater than the magnetic flux g of the permanent magnet 4:

p: f

then, under its influence, the movable contact part tends to turn so that the magnetic flux r coincides in direction with the magnetic flux / 2 and is parallel to it. As a result, the movable contact part turns in the direction of interaction of the total flux of the RE, pulls off the opposite fixed magnetic contacts 2, thereby closing the information circuit of the fixed optical fibers.

After removing the pulsed current from the sources of MDS, the fixed contact piece remains in the same position as the research institute, maintaining its original state, until the supply of the pulsed current to the next pair of sources of MDS.
