Automatic Reverse polarity switch using Relay ... Circuit diagram of Automatic Reverse polarity switch using Relay . But if we apply DC voltage wrong polarity, the diode is getting the reverse bias so the current cannot flow to the relay’s coil, the relay doesn’t work. It causes the positive voltage from lead C 2 flow through to lead NC 2 that is the output. And the negative way will flow ... Automatic Reverse polarity switch by Relay. – Circuit ... Automatic Reverse polarity switch by Relay. Posted by Circuit Diagram in Power Supply Diagrams. This circuit is an automatic reverse polarity switch. If we apply DC voltage to a any electronic circuits in wrong polarity. It can be caused by too much current. You must waste time to reverse the new terminal.
