What do you do when you want to switch on the light ?
you push on the switch….a little piece of metal connects the circutis….taddaaa light works, Relays are exactly the same….a switch, a little piece of metal that connects a circuit except that this switch is not triggered by your fingers, it is triggered by an electro-magnet. the electromagnet is a copper coil wounded around an iron piece, when this coil receives a small electric current, it turns into a magnet, this magnet moves the switch mechanically and press the switch on or off for you.
The main usage of relays is control….exactly like normal switches, you control a device ( say a big motor) to ON or OFF state.
you can control the switch automatically by sending a small signal to the electromagnet so this signal switches on the circuit of a big appliance like a water pump motor, washing machine, elevator motor….anything.
electronic controllers uses very low current and voltage, so in order (for example) to switch on your big desk lamp or room lamp or washing with your computer in a smart home system…you make a controller circuit to which takes the control signal.
Relays are used in electronics to switch a smaller current which in turn will control larger current. They prevent the user to have direct contact to the main device being controlled that might be holding high voltage. These devices are comparable to a remote c ontrol which is used to make a big electronic equipment work.
