===Meaning===
A '''switch''' is a [[Electrical Component|component]] in a [[circuit]] that can connect or break the [[circuit]] to control whether [[electricity]] flows.
===About Switches===
: A '''switch''' is anything that breaks a [[circuit]].
: An 'open' '''switch''' prevents [[electricity]] from moving around the [[circuit]].
: A 'closed' '''switch''' allows [[electricity]] around the [[circuit]].
: A [[switch]] is a useful safety device in a [[circuit]] so that the [[Electrical Current|current]] can easily be stopped. This prevents [[Electrical Component|components]] from getting too hot and prevent [[electrocution]] from a damaged [[wire]].
