Musical Killswitch[edit]

All of those who are listed as killswitch users are actually using the Toggle Switch of the guitar except for buckethead who's using a killswitch that it's purpose is to silence the sound briefly, when the toggle switch's purpose is to shut or turn the electricity of the guitar.

Internet[edit]

Anybody wants to help me out create an 'Internet' section for this article? --> http://www.crunchgear.com/2010/06/23/relax-president-obama-will-not-flip-an-internet-kill-switch/

Thanks! P@ddington (talk) 00:52, 24 June 2010 (UTC)

IMO it should be split off into its' own article. I've added a split tag. -- Gordon Ecker (talk) 08:26, 26 June 2010 (UTC)
Also, there should be more information on China's internet kill switch, and any other current or historical internet kill switches, I've added the globalize tag. -- Gordon Ecker (talk) 08:35, 26 June 2010 (UTC)

Oh absolutely. I knew it would eventually become its own article, but I kind of wanted to start it here. I think now might be the right time to split. Do you think the new article should be include the software bit, or should it be all about the Internet Kill switch? P@ddington (talk) 17:20, 26 June 2010 (UTC)

Btw Gordon, I have a random question... about skipping lines on Wikipedia. Let's say I want to skip a line between the tags you added and the text of the article (for appearance purposes.) How would I go about doing that? Seems like just skipping a line in the code doesnt quite do it... Can you help me out? Thanks! P@ddington (talk) 17:52, 26 June 2010 (UTC)

Yes definitely. CMTucker (talk) 23:07, 22 February 2011 (UTC)

Hardware[edit]

Too low info. 2.94.94.228 (talk) 19:09, 6 April 2013 (UTC)

Deus Ex (and other media)[edit]

features a very famous killswitch. why is it not in this article?!?!? —Preceding unsigned comment added by 212.183.126.95 (talk) 15:37, 28 April 2011 (UTC) Not only. Generally, this article lacks section "KillSwitch in popular culture", mentioning such importnant facts, like it is often depicted in works of science-fiction as device used to control and emergency kill people(!). This happens very often (like in mentioned DeusEx). Second very popular depiction is showing it as security measure for controlling AI (like depicted in book "Neuromancer" <they mentioned EMP bomb for disabling Artficial Intelligences gone rogue>, XFiles episode mentioned in article also uses phrase in this meaning.)77.253.23.158 (talk) 17:38, 7 May 2011 (UTC)

Elevators[edit]

Is this an American reference? I've only ever seen a stop button in hollywood films, never in an actual lift 94.247.241.90 (talk) 20:49, 10 May 2014 (UTC)

In modern elevators, the stop button is replaced with a key switch, to prevent misuse. Older elevators had stop buttons, although many have had the stop button replaced with a key switch.199.184.205.88 (talk) 04:29, 28 January 2015 (UTC)

Update Needed[edit]

The article appears to be behind the times insofar as it speaks of smartphone kill switches as something not yet in use. How a kill switch is activated when one no longer has the phone in one's possession would be useful information. Orthotox (talk) 17:24, 20 June 2014 (UTC)

kill switch - emergency switch[edit]

I see it as problematic to talk about a kill switch as the main overriding category and redirect emergency stop or emergency stop switch to kill switch.

There are different categories of an emergency switch or emergency stop switch as they work differently.

- kill switch, taking off the electricity to the machine
- a switch implementing a controlled stop, as for example active braking of dangerous components falls under emergency Stop.

There is also a difference between emergency switching off (kill switch) and emergency stop.

I also have not seen the use of the word "kill switch" in ISO 13850, there the talk is about Emergency Stop.

My proposal is, have a page emergency stop, redirect rather kill switch to it, and explain the different ways to implement an emergency stop.Jochum (talk) 14:53, 9 February 2015 (UTC)

I am inclined to agree. All the best: Rich Farmbrough, 20:57, 1 April 2017 (UTC).
I also agree. "Kill switch" is not the correct name for this article, nor should it be used throughout the article to describe the function of an emergency stop or emergency shut off. In my personal experience (which is not to say it's the final word on the matter, only as an example), the only context in which I have ever heard the term "kill switch" used was to refer to a disabling switch that prevents a vehicle from being started by a thief, by opening the starting circuit in a hidden location hopefully known only to the rightful owner. Usage of the term "kill switch" to refer to an emergency stop or process halt is slang or colloquial at best. I think this article should be retitled "Emergency stop" (or similar term we come to consensus on) and all instances of the phrase "kill switch" in the article should be changed to that, except for the very short section that actually talks about the vehicle disabling switch, which is a completely different thing. Darkest Tree Talk 19:24, 18 May 2017 (UTC)

I agree with Darkest Tree's comments and with Jochum's proposal. There should be a separate "Emergency Stop" entry which could be referenced by this page, simply because "kill switch" is a popular misnomer for an emergency stop. I would be prepared to contribute to an emergency stop page. I didn't want to just wade in and start hacking and slashing without the other users involved in this page being OK with it. I've written a whole series of referenced articles on this topic, see https://machinerysafety101.com/series/emergency-stop/. Macadk (talk) 17:57, 16 July 2017 (UTC)

"Machinery" section[edit]

Using a normally-closed switch will NOT stop accidental activation of the kill-mechanism. It will actually ACTIVATE the kill-mechanism if the wire breaks. This being preferable, an emergency stop when it isn't needed, to the alternative, pressing the button and nothing happens. That's the nature of a normally-closed switch. Pressing it breaks the circuit, as breaking the wire would do.

The same system is used on burglar alarms, at least the older type, not necessarily computerised ones. Sensors are all in series in a loop, all normally-closed. When a sensor trips it opens the circuit, as will a burglar trying to cut the wire to disable it. These two systems are common users of normally-closed circuits.

I'm happy to help with improvement to thsi section as well, as this an area of my expertise. See https://machinerysafety101.com/series/emergency-stop/ for backup.--Macadk (talk) 17:59, 16 July 2017 (UTC)

Minor removal[edit]

"On machinery controlled by a programmable logic controller, the emergency stop is designed in a way that it overrides the output of the controller."

This is certainly not universally true. For example, many machines I worked on had a separate process, running on the PLC. dedicated to the E-Stop which would kill the other processes and put the machine in a safe state.

All the best: Rich Farmbrough, 20:53, 1 April 2017 (UTC).

Willing to work on this section as well, as this is a part of my professional expertise. --Macadk (talk) 18:01, 16 July 2017 (UTC)
