![]() ![]() Switches are made to handle a wide range of voltages and currents very large switches may be used to isolate high-voltage circuits in electrical substations.ĬonceptDraw DIAGRAM is a powerful software for creating professional looking electrical diagram quick and easy. ![]() ![]() A relay is a switch that is operated by electricity. The mechanism of a switch may be operated directly by a human operator to control a circuit (for example, a light switch or a keyboard button), may be operated by a moving object such as a door-operated switch, or may be operated by some sensing element for pressure, temperature or flow. In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another. ![]()
