Dear sir,
Excellent work, i want to know about the relay diagram 12vdc and 220vac
Dear sir, I really appreciate the wiring, it’s quite easily to understand. I needs more of it to know, like water pomp motor.
I have to take exception with your control diagram.
The OFF push buttons should be shown normally closed.
The diagram above indicates that they are normally open resulting in the motor never starting.
