This addition gives the relay the property of time-delay actuation. The electromechanical relay can be defined as an electrically operated switch that completes or interrupts a circuit by physical movement of electrical contacts into contact with each other. In fact, some of the first digital computers were built with electromechanical relays as their active elements. However, it is not as robust as the Electromechanical Relay. Static relays were manufactured as semi conductor devices which incorporate … %�쏢 The manufacturing processes used to create these relays provides a cost effective solution for many switching applications, but users need to be aware of the limitations just as with any other relay technology.
