Please add[edit]

Please edit this sentence "Typically, the controller handle was a horizontal bar that is rotated to apply the required power for the train." to indicate along which axisthis bar is rotated. Is it turned around its shortest axis (like twirling a baton), or is it simply twisted along the long axis (like revving a motorcycle)?

Many treadmills carry this (optional) feature these days. I'm not sure if that deserves mention, so I'm suggesting it here. 00:54, 6 November 2006 (UTC)


I suspect Wikipedia is having problems. The history shows that I blanked the page, but I did not do this; I was trying to fix a typo. It also gave a couple fake "editing conficts"; the last was genuine (reverting the "blanking" that I "did"), but the first apparently was not. What's going on?

Strange. You may want to report the bug so the developers can figure out what happened: a string of page-blanking glitches could easily be mistaken for vandalism. -- 07:06, 1 Apr 2004 (UTC)


Should penalty switch, vigilance control, dead-man's switch and dead-man's control be merged? They are very similar. Andrew pmk 03:16, 23 May 2005 (UTC)

Yes, definitely. Go ahead and do it, please. Simon A. 11:28, 23 May 2005 (UTC)

Definitely. Also pilot valve. - Omegatron 23:50, July 10, 2005 (UTC)

  • Which one should be used as the main article name? I'm not a native speaker, but dead man's switch sounds best to me. Obli (Talk) 02:24, 15 January 2006 (UTC)
    • Dead Man's Switch is the one I remember most easily. --Alvestrand 01:56, 3 February 2006 (UTC)
      • Done! Obli (Talk) 21:07, 18 February 2006 (UTC)
  • Is this the same as a kill switch? - Shinglor 20:18, 19 June 2006 (UTC)

Problem with page[edit]

To whomever is updating this page:

You need to talk about Dead Man's Switch in regards to its application to nuclear warfare.

There is a link from the story 'Nuclear Strategy'.


deadmans' on trams in France[edit]

Hello, I am the one that put an external link on this page and it's been there for a while, but no information from it has yet been put into the article, could someone (please) do it?Myrtone@Dead man's 11:24, 26 May 2006 (UTC)


Regarding the edits concerning the word "alerter": I know that Microsoft Train Simulator uses the term, and they seem to refer to something similar to a dead man's switch. --Kabelleger 21:34, 9 July 2006 (UTC)


Maybe someone has a better image than the current one? I had to stare at the image for half a minute to figure out that it was a foot-pedal on a carpeted floor. If there is an image that illustrates it more obviously, that would be great. DancingMan (talk) 00:29, 30 November 2007 (UTC)

Is it really that ? I couldnt get anything at all. I hate incomprehensible images. Could someone get a better image as the main one, possibly keep this image as secondary and add a better caption. I'll message the original poster of the image.Machete97 (talk) 14:01, 23 May 2008 (UTC)

I'm the person who made the image... Had to do it with an old mobile phone camera, so my apologies for the poor quality. Should anyone have a better picture, please replace the current one with the new (better) picture. I just don't like articles without pictures, so I add them whenever I can. Even if their quality is so poor... Erik1980 (talk) 15:24, 23 May 2008 (UTC)

The picture quality isn't the problem, its just unclear what it is actually a picture of - it's incomprehensible. Machete97 (talk) 22:44, 24 May 2008 (UTC)

KISS principle[edit]

An exception to the popular KISS principle has been identified. It is noted that the KISS page has no concept of exceptions to this principle, it being some kind of imutable law, rather than a rule of thumb that can be broken as necessary. Something needs to be added to KISS principle to refer back to lessons learned on the railways.

In aircraft[edit]

Really!? How would that help? --catslash (talk) 01:47, 1 November 2008 (UTC)

I was just thinking the same thing...its use in aircraft seems not only dubious, but completely absurd.
[Edit] I've solved the mystery. Apparently, a dead man's switch is used in aircraft refueling. --drewster1829 (talk) 18:58, 15 January 2009 (UTC)

Original Research - rarity of deadman switches[edit]

"dead-man equipment was quite rare on US streetcars until comparatively recently"

That is a conclusion based on no source and not true. The Presidential Commission Cars (known as PCC_streetcars were almost the only streetcars built and used in the United States since before World War II, and were in use in some cities until the 1990s (and are still in use on Heritage lines) had a deadman pedal. So this claim is patently untrue. —Preceding unsigned comment added by (talk) 07:34, 21 July 2009 (UTC)

Tread Machine (you know for working out)[edit]

I added it as an example, because it is unique; it is not a tool. They have ones that clip on to you that pull out a plug incase you trip and fall. —Preceding unsigned comment added by (talk) 12:17, 5 December 2009 (UTC)

I fixed the link so it goes to treadmill. (talk) 17:30, 20 December 2009 (UTC)

Merge again[edit]

Two problems:

  1. article Dead-man's vigilance device needs to be merged here
  2. in this article, under Vigilance control there is contradictory text: "Main article: Dead-man's vigilance device", followed by "A hybrid between a dead man's switch and a vigilance control device is a dead-man's vigilance device."
