switch

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.
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. A relay is a switch that is operated by electricity. 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.

    Avoid getting scammed by 'Audiophile' network equipment - AQVOX Switch

    This is worth watching even if you already know something about networking and particularly if you don't. I found it interesting even though I wouldn't buy that stuff anyway. Companies like this need to be boycotted, name and shamed etc.!
