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

Switches should be placed on the [[hot line]] so that when they've turned off the electrical device (like a lamp) it is at the same [[voltage]] as the [[ground]]. This is 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 switches work in an [[electric circuit]]:
