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.
This is a very useful sit for we electrical guys
Hi
I am looking for circuit diagram to control a small lift (elevator) from two places with the three buttons on each location (down button, up button and stop button) for 220v motor. I wonder if you can help me with this circuit design.
thanks
Can’t understand how the holding contact would prevent the coil from going off.
