ASCO Series 300 Power Transfer Switches
... Where would you be without a constant flow of electrical power? We often take for granted that power will always be around when we need it. In reality, power failures are common, and when the power goes out, your business suffers. Power failures are unpredictable. They can occur at any time and for ...

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.
