WebA relay is an electrical component that can control the flow of electricity in a circuit. The relay can be energized at one time and de-energized at another. This allows the relay to open and close and interrupt and reestablish electric circuits. This blog post shows you the most important things you need to know about relays. WebWhat is Contactor? Definition: A contactor is a kind of electrically controlled controlling device. It is used as a switch to turn a machine on and off. The operation of the contactor is similar to that of a relay switch. The difference between the two is that the contactor can carry more load while the relay operates at a lower voltage. high lift platinum blondeWebUnlike relays, contactors are designed to make and break higher powered circuits without being damaged.
