FAQ:

Q: What is the function of relay?

A: Relays are utilized to protect electric power systems against trouble and power blackouts as well as to regulate and control the generation and distribution of power. it is used mainly for switching.

Q: How do relay switches work?

A: A relay is an electrical actuator that functions as a switch. It takes in as input an electric current and uses this current to close a switch. Thus, a relay is really a switch that is switched on and off by changes in the current input into it.

Q: How do relays work?

A: How Relays Work. Relays work taking an electrical current through them. In response to this current, the coil of the relay produces a magnetic field. This magnetic field then attracts the mechanical switch, closing it.

Q: What is an electrical relay?

A: An electrical relay is a switch that is under the control of another circuit. A classic example is the system used to start a car — when someone turns an ignition key, the ignition does not interact directly with the car battery.
