POLARIZED SINGLE-WINDING ELECTROMAGNETIC RELAY Russian patent published in 2021 - IPC H01H51/24 

FIELD: electrical engineering.

SUBSTANCE: invention relates to electrical engineering, in particular to low-voltage electrical devices and can be used for designing polarized relays, contactors, magnetic launchers and devices with hybrid switching. The device comprises two identical anchors with permanent magnets magnetized in the same direction and each of said magnets having a conductive support fixing the magnet, carriages are arranged at both ends of the electromagnet and the permanent magnets are magnetized in the direction matching the electromagnet winding field. Due to the above-mentioned, the same winding can be used for both activation and deactivation of relay contacts.

EFFECT: reducing the structural mass of the magnetic circuit, reducing the dimensions of the polarized electromagnet and simplifying the control of the relay characterized in that the voltage supply to the control winding for shorting and unblocking the contacts is carried out from a single button.
