Relay Switch Diagram. These output devices are commonly called actuators. The construction and working of a relay can be understood from the above diagram.
A relay is an electrically operated switch. A relay is a form of electrical switch that is operated by electromagnet which changes over the switching when current is applied to the coil. The high current circuit in this relay feeds power to the driving light bulb so every time headlight main beam is.
Wiring diagram also provides beneficial ideas for tasks that may require some extra equipment.
When a relay contact is open this will switch power on for a circuit when the coil is activated. It can be used for various switching. The main part of a relay is the electromagnet. Relay can be the best option to control electrical devices automatically.
