Switches
A switch is a device used in electrical engineering that has the ability to connect or disconnect a circuit's conducting line, halting the flow of electricity, or rerouting it to another conductor. An electromechanical switch, which has one or more sets of moveable electrical contacts coupled to external circuits, is the most popular type of switch. Current can flow between two contacts when they are touching, but it cannot when the contacts are apart.
