Key switch

A key switch is a switch that can be activated only by the use of a key. They are usually used in situations where access needs to be restricted to the switch's functions.
Key switches are available as components with solder connections, and are available with a variety of ampere ratings. They may use tubular or other specially-shaped keys for extra security.〔
Key switches have been used for a variety of purposes, up to and including the launch of nuclear missiles.〔
In less secure applications such as corridor and restroom lighting controls in public buildings, tamper-resistant switches with a simpler key mechanism may be used instead.〔(【引用サイトリンク】url=http://www.ncef.org/pubs/low_cost_measures.pdf )〕〔(【引用サイトリンク】url=http://www.leviton.com/OA_HTML/ibcGetAttachment.jsp?cItemId=xreQ9kM.SwSAGa6JaqTCzw )
