The invention relates more to an electric technology, in particular, to a low-voltage electric apparatus, and can be used in a relay, a contact pax and a starter.

The purpose of the invention is to reduce the material intensity, the labor intensity of manufacturing, increase the vibration resistance of the apparatus and increase efficiency.

Figure 1 and 2 shows the proposed device.

The device contains a turning coil I ,, located on the core 2 between the magnetic cores 3, elements 4 and 5 of the core mounted on axis 6, fixed contacts 7, traverses 8 with movable bridge contacts connected by means of pads 9 with hinges 10 and return springs 11 installed between the ends of the core elements.

The device works in the following way.

When applying to the switching coil. 1 of a voltage sufficient to move the core, elements 4 and 5 of the core, under the influence of the magnetizing force created by the coil, rotate around the axis 6. In this case, the ends of the core elements move (Fig. 2) until they touch with the corresponding surfaces of the g-and magnetic circuits 3, while performing counter-parallel movement. The movement of the core elements through the pads 9, which are hinge-linked to the ends of the elements and the crossbars 8, causes the movement of the crossbars with the contacts. The contacts are closed and the load currents are switched. When the voltage is removed from the coil under the influence of return springs 11, the movable part of the apparatus returns to its original state.

Due to this implementation of the device, it is possible to increase the efficiency with the same dimensions twice, to simplify the assembly technology, to reduce material consumption and weight. The symmetrical arrangement of the contact cross-arms allows, without additional costs for materials and adjustment work, self-. to balance the mobile system not only in statics, but also in dynamics and increase the vibration resistance of the device.
