== Bit Switch ==

The switch is a way to pass the state of the input bit to the output of the switch, but only when the switch is in the enabled {{On}} state.  The {{Off}} state prevents the input bit from being passed through to the output.

== Word Switch ==
{{Infobox component
| image        = Word_Component_switch.png

}}

The word switch functions similar to <code>width</code> individual bit switches.  However the enable pin remains a 1-bit value, enabling or disabling the entire the input line at the same time.
