How do you wire up a 2 way switch?

I understand how the 2 way switching works, I am just unsure of the "best" way of implementing it.

The best way I can see of doing it is using SDI from each switch back to the light, a twin active between the two switches and have a supply feed to the back of the light. One of the SDI carries the active supply to the switches, the other SDI is hooked up to the light's active. This is exactly how i have done it for an irrigation pump before. But in this situation, the pump and supply were in the same location, which made using SDI to each switch the best solution anyway.

Is there a better way of doing it, ie, without the SDI links, and preferably by taking the supply down to the light switch (since its already there anyway)?

Oh, I realise this should all be done by a licenced electrician so no need to drum that into me.

Correct, if you feed is alread at your light: You need a SDI to supply the feed to the 1st switch, then a twin between the two switches and the second SDI as the switch, it can run back with the twin or exit above the second switch

If your feed is at the switch: Very simple, switch or both switches hve feeds, add the twin between the two, and run a switch wire(RBE) from the best position, and feed the other common ternimal

Also im assuming you know how to two way a switch?

Or if from an existing switch you can run 3 strappers from the existing switch to the new one, negating the need to access the light

yeah if its existing, then this would be the easiest option

Yep i understand the two poles etc.

So by your second option, when you say "feed the other common terminal" this means run an SDI from the switch not connected with the RBE, back to the other switch, which I then join to the active headed to the light?

ie, there are 3 actives running between the two switches?

ok, thats what i was thinking, 3 strappers means 3 sdi's? or a triple active?

Or a twin an SDI ...Active in 1 and Switch wire in 2, or vice versa, strappers 1-1 C-C 2-2

ok thats what i will do, i have an existing light, i want to loop another light off it, and then two way switch it at either end of the garage.

[jet-6]

The last option is the best for you, a twin and a sdi or 3 sdi's, its all the same!

[lump_a_charcoal]

But of course the licenced sparkie who does it for you will know the best way!

Once you get one light working, then loop off it... No need confusing the situation.

I googled that image myself, but when i read it, it appears to be a UK wiring standard, not AUS, ie, 2 wire supply etc.

I understood how the 3 way switching works, i was just unsure of how to effect the wiring to meet the australian standards.

teh third wire is simply ground. Its not switched. if you want just run it straight to your light socket. Alot of appliances do not use ground from the power point. and i think the standard changed recently so that even your lightbulb socket must have ground.

Jes

standard changed in at least the 2000 update of the AS3000 (probably even 97) requiring twin+earth for lights.

Im quite familiar with electronics, being an electronic engineer and all >_<, just not so familiar with the finer points of mains electrical work.

OOOOOOOOOOOOOOkay

[Shadow]

i just ended up pulling 3 SDI's through

sparky's problem now when he comes to do the fitoff ^_^

built in a garage, didnt want sparky to come out to move 2 power points and add 3 runs of sdi, but he can come do the fitoff
