How do you understand that part of monostable relays and all magnetic holding relays are polarized relays? Is the polarization monostable equivalent to a single coil magnetic hold?
Some polarization relays are designed for two coils, said in order to get a simple reverse control.
Ordinary relay to electric pull, power off. Polarization relay is in the coil to the moment the relay will be stable in a state, the coil reverse to the power conversion state
