Introduction: Useful Deadman's Switch (interruptor De Pie)

Picture of Useful Deadman's Switch (interruptor De Pie)

Esta es una herramienta que hay que tener. Lo que digo podrà parecer una tontería a algunos, pero este "cable en Y" a mí me resulta casi imprescindible. Sin él no podría utilizar con comodidad varias herramientas eléctricas de mano o de mesa, y consecuentemente muchos trabajos se me complicarían.

This is a "must have" tool. What I say may seem silly to some, but this "Y cable" is almost essential to me. I couldn't comfortably use various power tools –hand or table– without it, and consequently much work would be very diffucult for me.

Step 1: Descripci�n (description)

Picture of Descripci�n (description)

Es simplemente un cable con interruptor pulsador, para accionar con el pie.

La siguiente descripción detallada es mucho palabrerío para despejar cualquier duda, pero lo más probable es que Ud entienda con solo ver las fotos cómo hice el interruptor de pie.
  • Compré 4 m de cable de taller, apto para 15 amperes. Usted puede necesitar cable más o menos grueso, según lo que vaya a alimentar.
  • Corté un trozo de aproximadamente 1m.
  • A este le coloqué en un extremo un interruptor pulsador, o sea con resorte de apertura, montado sobre una pequeña base de madera.
  • Al trozo de 3m le puse fichas, un macho en un extremo y una hembra en el otro, como si fuera una prolongación.
  • Luego le hice una muesca a 1m de un extremo, quitando la aislación de goma.
  • Una vez descubiertos los cables, corté uno de ellos con el alicate.
  • Quité 1 cm de la aislación de ambas puntas del cable recién cortado.
  • A estas puntas les soldé con estaño los extremos del cable que tiene el interruptor.
  • Aislé todo con vaina termocontraíble.
  • Reforcé la Y con vaina termocontraíble.

It is simply a cable with push-button switch, to drive with your foot.

The following detailed description is much chatter for the avoidance of doubt, but the chances are that you understand just how I see the pictures foot switch.
  • I bought 4 meters of workshop cable, suitable for 15 amps. You may need more or less thick cable, as to be fed.
  • Cut a piece of about 1m.
  • In that I placed at one end a pressure switch, it is to say with opening spring, mounted on a small wooden base.
  • The piece of 3m chips I put a male on one end and a female on the other, as if it were an extension.
  • Then I made it a notch at 1m from one end, removing rubber insulation.
  • Once peeled off the wires, I cut one of them with pliers.
  • I removed 1 cm of insulation from both ends of freshly cut cable.
  • These tips are soldered with tin to the ends of the wire that have the switch.
  • Insulate all with heat shrink tubing.
  • Reinforce the Y with heat shrink tubing.

Step 2: Uso (use)

Es casi una obviedad, pero por las dudas alguien hasta este momento no haya entendido el propósito de esta derivación en Y, acá va una explicación:

Se enchufa en la toma de pared el enchufe correspondiente, o sea el macho, y en la hembra se enchufa la herramienta. Esta debe estar con el interruptor en posición ON. El interruptor del cable Y debe quedar al alcance del pie, de modo que al pisarlo, la herramienta arranca. Esto es muy útil cuando se necesitan ambas manos libres para sujetar la herramienta y/o el trabajo.

This it is almost obvious, but just in case someone so far do not understand the purpose of this Y derivation, here is an explanation:

You plug into the wall socket the male plug, and in the female plug the tool. The tool should be with the switch ON. The push switch of the Y cable must be within reach of the foot, so the tool will start when you step it. This is very useful when you need both hands free to hold the tool and / or work.

excelente idea!!, es mi primer comentario en la pagina!!
la voy a tener en cuenta para futuros proyectos.
Saludos desde Bahía Blanca!!

Gracias, Chuliano. Ese cable tan sencillo es una de las cosas que más uso en mi taller: me sirve para el torno, la mesa de corte, el taladro de banco, la lijadora de banda puesta "patas parriba" y algún experimento con HHO últimamente. Le cambié el tomacorriente de salida por uno doble, para poder usar la aspiradora junto con el torno.

Thermo heat sleeve transliterates to "heat shrink tubing", at least in American english. Good work!

Done, thanks!

Hola Rimar, buen instructable como siempre!

De título pone "Dead man's switch", es así como le llaman ellos (por ende vas a tener muchas más visitas porque van a entender qué significa).


rimar2000 (author)DriX2011-06-10

Gracias DriX, ya le cambié el nombre como tres veces. Hecho según tu sugerencia.

Hi Rimar, cable can refer to many things so in that way the title is a little confusing, of course it could be the translation since my spanish is somewhere around ZERO, I don't really know. Perhaps "a useful electrical switch" or " a useful workshop switch" would be less confusing. Personally I didn't know what it could mean so curiousity made me look !

I can see where this switch would be very useful and since its a "deadman" very safe. I often use the type of extension cord that is fused and switched, like that used for computer safety, as a remote on/off switch

rimar2000 (author)l8nite2011-06-08

Thanks, I8nite, I will change the title.

To be honest, I was a little confused - to me, a 'y-cable' is a headphone-splitter (2 sets of headphones into one socket), but I knew that you, rimar2000, wouldn't be publishing such an Instructable... ;-)

So I clicked through, and learned something very useful - Thank you.

If I used this on a 'Table Saw from Circular Saw', it'd solve the problem of starting and stopping the saw whilst the buttons are held in by whatever means. AND it'd be safer, too, because if anything happened with such a 'home-built' conversion, the switch would cut out immediately the pressure of my foot was lost!

S, Thank you again, rimar2000!!

rimar2000 (author)karlpinturr2011-06-07

Thanks for the comment karlpinturr, I changed the name to "Useful cable tool (útil cable Y)"

I guess I would call this a "foot switch" or a "momentary foot switch". Some people might call it a "dead-man's switch", meaning it would automatically switch off if the operator was not present and attentive.

I don't know where I would get a momentary switch that would be rated to accept 15 amperes at 117 volts off the top of my head, but I'm sure they make them.

I've used a foot switch like this that was built-in to some book binding equipment.  This might be good for use on an improvised lathe or something. What kind of tools do you use this with?

kill-a-watt (author)kill-a-watt2011-06-05


It looks like your local power is 220 volts.

rimar2000 (author)kill-a-watt2011-06-05

Yes, here we use 220 V.

I asked by a "robust" pressure switch, and I bought the best they offered me. There was not much to choose from. So far it is holding, and it takes more than a year of use.

Before this, I had another similar cable with a much more precarious switch, without problems.

I use it with my desk belt sander, my KISS lathemy poor man's lathe, my table support for drill, and eventually other electric tools.

Do you think that the title of the instructable is not suitable? I like it as is...

kill-a-watt (author)rimar20002011-06-06

I'm sure that the title is fine. I figured out exactly what you were building right away.
