What is a Switch? A switch can be interpreted as on and off. It also refers to an electronic accessory that can open a circuit, interrupt the current flow, or cause it to flow to other circuits. The most common switches are human-operated electromechanical devices that have one or more electrical contacts. The "closed" of the contact means that the electronic contact is turned on, allowing current to flow; The "open circuit" (open) of the switch means that the electronic contact is not conductive to form an open circuit, and no current is allowed to flow.
