Relays and transistors are the two most common electrically actuated switches used in electronics; however, they are not perfect replacements for each other. Relays and Transistors Unique Characteristics Relays and transistors are multi-terminal devices that provide switching functions. In both components, switching is actuated by applying an electrical voltage/current, but the exact mechanism by which current is allowed to flow through the switch is different in relays and transistors. Relay switching: A relay is a mechanical switch triggered by using an electric current to generate a magnetic field near an armature. A magnetic field is generated in a coil, which...
