Editing Dead man's switch (section)

===Key switches===
On recreational vehicles such as boats, [[personal watercraft]] and snowmobiles, and on the control panel of many [[amusement ride]]s, the user or operator has a cord or lanyard attached to their wrist or life jacket, that is in turn attached to a [[Key switch|key]] mounted on the dead man's switch. Should the rider fall off the vehicle or the operator at least move away from the controls, the cord will be pulled out of the dead man's switch, turning off the engine or setting the throttle position to "idle". On powered boats in particular this cord is often called a "kill cord" (for powered boats use around the wrist is not recommended, as it may slip off without cutting the engine).<ref>{{cite web|url=http://www.rya.org.uk/cruising/safety/Pages/Useyourkillcord.aspx|archive-url=https://web.archive.org/web/20130117003954/http://www.rya.org.uk/cruising/safety/Pages/Useyourkillcord.aspx|archive-date=2013-01-17|access-date=2013-05-07|title=Use your kill cord|publisher=[[Royal Yachting Association]]|website=RYA.org.uk}}</ref><ref>{{Cite web|date=2020-02-14|title=Kill Cords|url=https://chieftain.training/kill-cords/|access-date=2020-06-03|website=Chieftain Training|language=en-GB}}</ref> If the helmsman goes overboard or is forced away from the controls, the engine cuts out. This prevents the boat from continuing under power but out of control, risking injury to anyone in or out of the water including passengers who may have fallen out or may still be in the boat, and collision damage to any property in the path of this out of control boat; this in turn prevents or limits damage to the boat itself from striking other objects. It is a common and dangerous practice to defeat the kill cord by fixing it to part of the boat instead of the operator; for convenience. This has been the cause of accidents, some of which were fatal or caused limb loss.<ref>{{cite news |first=Steven |last=Morris |url=https://www.theguardian.com/world/2013/may/06/cornwall-speedboat-accident-police-rescuers |title=Cornwall speedboat accident: police pay tribute to rescuers |work=[[The Guardian]] |date= 6 May 2013|access-date=2013-11-15}}</ref>

Some luggage carts at airports and exercise [[treadmill]]s have this feature. In the case of treadmills, the dead man's switch usually consists of an external magnet attached to a cord that clips to the user. If the user falls or walks away without turning off the treadmill, the switch cuts power to the treadmill belt.

In [[Physical information security|information security]], kill cords are also used in computers to turn off the machine if the user is separated from it.<ref>{{cite news |first=Anton |last=Shilov |url=https://www.tomshardware.com/news/buskill-usb-cable-now-available-a-pc-kill-switch-for-data-protection |title=BusKill USB Cable Now Available: A PC Kill Switch for Data Protection |work=[[Tom's Hardware]] |date=15 Dec 2021|access-date=2022-07-02}}</ref><ref>{{cite news |first=Jean-Luc |last=Aufranc |url=https://www.cnx-software.com/2021/12/15/buskill-usb-kill-cord-protects-data-on-linux-windows-mac-os-devices/ |title=BusKill USB kill cord protects data on Linux, Windows, Mac OS devices |work=CNX Software |date=15 Dec 2021 |access-date=2022-07-02}}</ref>
