How do control relays work
WebA very common form of schematic diagram showing the interconnection of relays to perform these functions is called a ladder diagram. In a “ladder” diagram, the two poles of the power source are drawn as vertical rails of a ladder, with horizontal “rungs” showing the switch contacts, relay contacts, relay coils, and final control ... WebJun 27, 2024 · Here, we discuss the step-by-step procedure to make a latching relay circuit. Step-1 Connect Relay with a push-button and DC supply as shown in the figure below. Push-button is Normally an Open (NO) switch. Therefore, initially, the switch is open. When the push button is pressed, the relay gets ON.
