An electrical knife switch is a mechanical device used to control the flow of electric current in a circuit. It consists of a pivoting metal lever, resembling a knife blade, which can be manually flipped to either open or close the circuit. The switch is typically mounted on a non-conductive base, and the blade is connected to the circuit's conductive components. When the blade is in the closed position, it allows the flow of electricity through the circuit, while in the open position, it interrupts the flow, effectively disconnecting the circuit. Electrical knife switches are commonly used in industrial and residential applications, offering a simple and reliable method for turning on and off electrical power to various devices or systems. With their straightforward operation and visible status indication, these switches provide a convenient means of controlling electrical circuits and ensuring safety in electrical installations.
