ELECTROMAGNETIC RELAY WITH TWO STEADY POSITIONS Russian patent published in 2015 - IPC H01H51/22 

FIELD: electricity.

SUBSTANCE: electromagnetic relay unit contains the rotating unit of the electromagnetic coil, the first and second pairs of permanent magnets located opposite to each other and the switch assembly. The coil unit contains the coil, the core and the rotating coil housing. The coil is winded on the core. The core contains opposite ends of the core, and the coil housing has a rotation axis, perpendicular to the coil axis. Pairs of magnets are fixed and located near the respective ends of the core so that the core ends can move between pairs of magnets. During the work process the coil generates the magnetic field directed through the core for rotation of the coil housing around the rotation axis at the expense of attraction to the positioned/fixed magnets. The core ends displace the connecting levers, and the connecting levers make to move the contact spring units of the switch assembly between opened and closed positions.

EFFECT: improvement of resistance of the electromagnetic relay to unauthorized action by means of a magnetic field.
