Thread: Need wiring diagram for two switches.

Anyone know how the switches a wired together..

Andy, better brace yourself, there will be incoming............along the lines of "if you don't know how to do it, don't"!

BTW, the safe way to do it is to get a remote control for the DC, I have one and can switch the thing on/off from anywhere in the shed.

Hello,

If you don't know how to connect electrical, DON'T TOUCH.
Otherwise,

Hi, yes I know electricity is dangerous....

I have put my hand across live voltage on several occasion in the dark room, touching equipment with wet hands...

(one the flash was so bright that staff outside the darkroom saw the flash, and the darkroom was ment to be light tight... This was before safety circuits, and I was only employed there. the studio had been wired for electricity in the 1910's. so almost all was true 'Ancient' wiring)

Now EVERYTHING I have has safety circuit breakers on them... dohhhhh.

but telling me anything is dangerous, is just waving a red flag as a bull... (noting infuriates me more, than when I want to learn something, and people wont teach me... happened all my life... my uncle agreed to teach me how to use a lathe, and then reneged... and got highly infuriated when I turned out better work than him. even though I was self taught, and he lectured at technical colleges... If anything I am a fast learner... that is why I joined this board... to learn....)

But a circuit diagram would be more helpful than telling me off... (and more appreciated. criticism is no replacement for help...)

Though your point is well noted, and accepted... (I have been 8 times in coronary intensive care, and only twice in emergency for accidents in the hobby room... so I have less accidents than I do anything else... hahahahaha... and can certainly take criticism, and can also dam well hand it out also... hahaha)

regards, Andy

If you don't know which wires connect together and connect the wrong cables together, you may cause serious damage to your electrical board and maybe to yourself and others.
This is why i recommend you DON'T TOUCH.
Sorry about my first reply, Now i know that you have worked with electrical
before and know the basics, You will be able to wire this light switch yourself.

The link i have included will show you how to do this, hope i could help.

Just a little point here.
What you are asking is just a little on the illegal side of things.
I now refer you to the forum rules & safety instructions.
Bravado doesn't cut it....safety does

One might expect that someone who has experienced as many life threatening experiences as you might have learned that those 4 letters only appear once together for one individual.

I have to admit I'm a little like yourself - I can do it.

Others here have offered advice to keep you safe as I'm sure many others may have done in the past.

Use those 8 letters and sail life safe.

It's better for you and more importantly those around you that matter.

You might also like to consider what your insurance company may think - electrical work should include a certificate of completion (or some such name).

Whether wiring the dust collector as proposed is legal or not will depend upon which side of the power point the wiring is done. If the 2-way switching is done after the power point (i.e. the 2-way switch wiring is between the 3-pin plug and the dust collector) then no licence is required.

All said and done, I'd think BigShed's suggestion of using a wireless remote is probably the way to go.

And might work out the same cost or cheaper

Hi Andy,

I've wanted to do the same but just without the rewiring part. If you're all on 10Amp equipment, you may get away with one of the master/slave devices already on the market. Most are geared towards energy saving when you turn your TV off it will turn off all your ancillary devices.

You may want to keep an eye on this thread for development of a 15Amp version. Of course, I don't condone doing your own electrical work and do definitately consult a qualified electrician when dealing with this stuff.

Cheers,
Af.

If it requires 15amp I think you may find that 15amp two way switches are not available because I know for sure that cross over switches aren't made in 15amp

I am sure that is not true in all jurisdictions, even if it is in yours.


fwiw I can be done with any number of switches, I learned in "Computer Organisation" at CCAE in the 70s. I don't recall how now though. Google for "exclusive or" and/or xor, I think those should lead to it.

Silicon chip magazine (Issue number 238) had an article about two way lights last year.

The article explained that there are ways shown at sites on the internet that work but are dangerous.
