Abstract

The invention relates to switching devices and may find application in the design of relays and switches used in fixed equipment. The purpose of the invention is to expand switching capacity and increase sensitivity. When a control signal is applied to any two stationary contact electrodes (EC) 3 installed in the wall of a sealed balloon (GB) 1, they are magnetized and attract a movable EC 2, made in the form of a needle and freely located in GB 1. CE 2 bridges stationary CE 3, because the distance between the contacting surfaces of the stationary CEs does not exceed the length of the movable CE. When the control signal is applied to any of the stationary CE 4s installed at the end of GB 1, the mobile CE 2 moves in its direction along guide 5 before closing with them. In this position, CE 2 can switch the current, bending and contacting, with its free end, stationary CEs. When removing control signals from all control coils, the mobile CE 2 remains in a closed state with a pair of stationary CEs, depending on the arrangement of GB 1. 2 silt; (Oh (L

The invention relates to kimmutational devices and can be applied in the design of relays, switches used in stationary equipment.

The purpose of the invention is to enhance switching capabilities and increase sensitivity.

FIG. Figure 1 shows a magnetically controlled contact, a longitudinal section (the dotted lines indicate the possible positions of the moving contact electrode during switching); in fig. 2 shows section A-A in FIG. one.

The magnetically controlled contact contains a sealed cylinder 1, a movable contact electrode 2, stationary contact electrodes 3 mounted in the walls of the cylinder, stationary contact electrodes 4 installed at the ends of the cylinder, and guides 5 seamlessly coupled to the wall of the sealed cylinder one.

The movable contact electrode 2 is made in the form of a needle and freely located in the sealed cylinder 1, and the distance between the contact surfaces of adjacent stationary contact members connected to the guide 5 of the inner wall of the sealed cylinder 1, enters the guide 5. Diameters of the movable contact electrode 2 and the guide 5 are close, and the movable contact electrode 2 is connected with it by the force of the attraction of the fixed contact electrode 4 and is thus securely fixed in the guide 5, thus forming m console contact element. In this position, the movable contact electrode 2 can switch the current, bending and contacting its free end with stationary contact electrodes 3 installed in the wall of the balloon 1. Similarly, the movable contact electrode 2 is placed in the guides of the opposite end.

If it is necessary to release the movable contact electrode 2 from the guide, the control coil of the stationary contact electrode 4 installed in the opposite end of the balloon 1 and one of the stationary contact electrodes 3 mounted in the wall of the balloon 1 are magnetized.

electrodes does not exceed the dpins of sub-30. Then, turning off the power of the coil of the fixed contact electrode 2. All contact electrodes are made of ferromagnetic material.

The device works as follows.

The control coils are wound on the leads of each fixed electrode 3 and 4 (not shown). When a control signal is applied to any two stationary contact electrodes 3 installed in the wall, they are magnetized and attract the moving contact electrode 2, which bridges them. Due to the fact that the movable contact electrode 2 is made in the form of needles of a small mass, it quickly moves under the action of a magnetic field, which is not required to control large currents.

In the case when one end of the iodine contact electrode 2 needs to be fixed, the control signal is fed to the coil of one of the stationary contact electrodes 4 installed at the end of the sealed balloon 1. Under the action of magnetic forces, the movable contact electrode 2 moves towards slippery

the movable contact electrode 4 at the end in which the movable is fixed, under the action of the magnetic field of the movable contact electrodes 4 installed in the opposite end and in the wall, the movable contact electrode 2 emerges from the guide and bridges the contacting surfaces of the fixed contact electrodes 3 installed in the wall .

When removing control signals

from all control coils, the movable contact electrode 2 remains closed with the stationary ones located in the lower part of the wall of the horizontal cylinder 1. By rotating the cylinder, it is possible to switch the control supply bypass circuits.
