Switches

A switch is an electrical component that can break a circuit, interrupting the current or diverting it from one conductor to another. The 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… More

A switch is an electrical component that can break a circuit, interrupting the current or diverting it from one conductor to another. The 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. Less
