Electrical contacts The National Association of Relay Manufacturers and its successor, the Relay and Switch Industry Association define 23 distinct forms of electrical contact found in relays and switches. Of these contact forms, the following are particularly common: Form A contacts. Form A contacts ("make contacts") are normally open contacts. Relay Time delay relay contacts must be specified not only as either normally open or normally closed, but whether the delay operates in the direction of closing or in the direction of opening. The following is a description of the four basic types of time delay relay contacts. First we have the normally open, timed closed (NOTC) contact. How Relays Work | Relay diagrams, relay definitions and ... Relays are switches that open and close circuits electromechanically or electronically. Relays control one electrical circuit by opening and closing contacts in another circuit. As relay diagrams show, when a relay contact is normally open (NO), there is an open contact when the relay is not energized. 10094620 Normally Open vs Normally Closed RevA Normally Closed vs. Normally Open The circuit part of the relay has two ways to which the wires leaving the relay can be connected, as either “Normally Closed” or as “Normally Open”. On the connector these two options are indicated as “NC” and “NO” as seen in Figure 1. Normally Closed Relays vs Normally Open Relays | What's ... Normally open relay: Normally open relays default in the open position, meaning that when they’re not in use, there is no contact between the circuits. When power is introduced, an electromagnet pulls the first circuit into contact with the second, thereby closing the circuit and allowing power to flow through. ... Please Explain A Normally Open Relay VS. Normally Closed A normally open is one that is an open circuit until you put voltage and a signal to it. A normally closed relay is one that is a complete circuit and therefore allows voltage to pass through it until it gets a signal and then it opens the circuit. Think of your relay as if it were two ends of as wire.
