| <onlyinclude>A '''switch''' is an electrical component that breaks or closes a [[circuit]]. Opening the switch (breaking the circuit) means turning off the electrical device and closing the switch (completing the circuit) means allowing electrical [[current]] to flow so that the device is on.</onlyinclude>

| Switches should be placed on the [[hot line]] so that when they're turned off the electrical device (like a lamp) is at the same [[voltage]] as the [[ground]], to reduce the risk of [[shock hazard|electric shock]].

| ==PhET Simulation==
| |
| The [http://phet.colorado.edu/ University of Colorado] has graciously allowed us to use the following PhET simulation. This simulation explores how electrical signals respond to a switch. The electrical signal sent through a [[wire]] when a switch is opened, or closed, travels much faster than the [[electron]]s in the circuit. Please play with the simulation to explore how a switch turns on and off [[household electronics]].
