Two position relay , As the name suggests, it means that the relay has two positions , At the same time, it can keep itself in both positions . actually , The two position relay is a magnetic holding relay with two coils .

coil A After power on , Relay contacts act , Even if it loses power , The contacts do not return ; coil B After power on , Relay contact return , Even if it loses power , The contacts will no longer act . in other words , If the contact position of the two position relay is reversed , There must be a coil live .

Two position relay is common in secondary circuit of substation , Mostly used to maintain status 、 In the circuit with high reliability requirements . Such as voltage switching circuit of double bus connection and voltage parallel circuit .

Two coils of the two position relay are respectively connected to each other's auxiliary contact , For example, coil I To connect the coil in series II Auxiliary contact of , coil II To connect the coil in series I Auxiliary contact of , In this way, the coil will not work with electricity for a long time , Secondly, the coil can be kept at I Bit or II position .
