The invention relates to electrical engineering and can be used in automatic devices.

The purpose of the invention is the expansion of operational capabilities.

Fig 1 shows the switch, cross section; in fig. 2 shows section A-A in FIG. one; in fig. 3 shows a section BB in FIG. one; in fig. 4 shows a section B-B in FIG. 1, in FIG. 5 is a section of G-Gnafig. ; in fig. 6 is an electrical circuit diagram of a switch with leads intended to be connected via a resistor to a direct current source.

The switchboard contains a hermetic enclosure 1, a control electromagnet 2 with a distinctly pronounced pole, a coil 3 windings, a rm 4 electromagnet, an internal ceramic plindr 5, a metal-Ki; t cover 6, a base (7 and an additional 8 non-standard electrically conductive , movable electroconductive rings 9, reinforced on V1gugg-CH1 ceramic cylinder 5, not | kx: viscous electrically conductive 10 and 1) colp.

The sealed housing 1 and the ceramic1 cylinder 5 of the switch are made of a material that is relatively easily soldered with metals, which makes it possible to strengthen the covers 6 of the housing 1 very easily and create a seal in it.

The winding 3 of the control electromagnet is located in the stump of the sealed space, which excludes the possibility of gas evolution when the winding is heated into the sealed space and the loss of vacuum in it,

automation devices controlled, for example, by a ring circuit, both in combination with contactless elements and without them. The latter ensures reliable operation of the device under radioactive conditions.

To ensure switching power (x electrical circuits, the space inside the sealed enclosure is filled with an inert gas (nitrogen, argon, gas, etc.).

When voltage is applied to the terminals of the additional stationary electrically conductive segments, current flows through the coil 3 of the control electromagnet winding, which at this time is closed with the current source through the zero point of the coils in the star, one of the additional stationary electrically conductive segments 8, a movable electrically conductive ring 9 located on a movable ceramic cylinder;, a fixed electrically conductive ring U) and the second pole of the current source. Due to the fact that the coils of the winding 3 are displaced in space relative to the conductive segments 8 by an angle equal to half the angle of their displacement relative to each other, the coil 3 attracts the movable ceramic cylinder 5, causing

Then the process is repeated, rolling the cylinder 5 rolls along the cylindrical surface of the fixed contacts of electrically conductive rings 10 and electrically conductive segments 7 and 8, providing alternate short circuit of the stationary electrically conducting ring 10 with the electrically conductive segment 7 of a controlled multi-channel system.
