`Electronics: Switches`
	`Switches are used to make or break an electrical circuit. They can also be used to divert the current path into one of two or more directions (ways or throws), and can also switch more than one circuit at once. For example, a double pole double throw switch (dpdt) can be used as either an "on/off" or "changeover" switch controlling two circuits at the same time.`
