Key switch
<templatestyles src="Module:Hatnote/styles.css"></templatestyles>
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.[citation needed]
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.[1]
Key switches have been used for a variety of purposes, up to and including the launch of nuclear missiles.[2]
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.[3][4]
