text: So relay is a switch which controls (open and close) circuits electromechanically.
text: The advantage is that one coil consumes power only for an instant while the relay is being switched, and the relay contacts retain this setting across a power outage.
text: As we have seen that relay is a switch.
text: So relay is a switch which controls (open and close) circuits electro-mechanically.
text: Thus, a relay is really a switch that is switched on and off by changes in the current input into it.
text: A relay is simply a switch that rather than being operated by hand, it is operated by an electromagnet (coil of wire which generates a magnetic force when an electrical current passes through it).
text: Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can be thrown by energizing the coil.
text: Since relays are switches, the terminology applied to switches is also applied to relays; a relay switches one or more poles, each of whose contacts can bethrown by energizing the coil in one of three ways:
text: Relays are basically switches, switches that you control (turn on or off) by applying or removing a specific voltage to the relay device.
text: A relay that doesn't need to be switched very often can last a long time.
