Electric Relays are switches that use electromagnetism for converting small electrical stimuli into larger currents. The process of conversion occurs when electrical inputs tend to activate electromagnets to either form or break existing circuits. This is commonly used in the control panels, building automation to control the power, and manufacturing for controlling the power values in a control circuit.  It controls the opening and closing of the circuit contacts of an electronic circuit. There are two types of electric relays: electromechanical relays have an electromagnetic coil and solid state relays. If you are interested in Electric Relays, you should contact Ajay Engineers.
