What is relay and type?

Question

Accepted Answer

A relay is an electrically operated switch that uses an electromagnet to mechanically control the switching action.

Relays are used to control high power or high voltage circuits with a low power signal.
They can be classified into different types based on their construction and operation, such as electromagnetic relays, solid-state relays, thermal relays, etc.
Electromagnetic relays use an electromagnet to control the switching action, while solid-state relays use semiconductor devices.
Thermal relays are used to protect motors from overheating by monitoring the motor's temperature.
Examples of relays include automotive relays, power relays, time delay relays, etc.

Accepted Answer

A simple electromagnetic relay is made up of a solenoid, which is wire coiled around a soft iron core, an iron yoke that provides a low reluctance path for magnetic flux, a movable iron frame, and one or more sets of contacts. The three main types of relays are electromechanical, solid-state, and reed.
