The polarized relays
The polarized relays of the RP-4, RP-5 and RP-7 types are output elements of various relay devices. Feature of the polarized relays is that the mobile anchor of the relay in initial conditions is affected by forces of a permanent magnet, when passing current in an electromagnet force relay winding depending on the direction of current develop with forces of a permanent magnet or are subtracted from them
