Help with wiring two way light

Help with wiring circuit to wire a light in my aft companionway. My poor old brain cant get around this one @#^%%#$*.
I would like to have a single switch each end of my companionway to turn on and off a light in the passage from either end. I know it can be done but cant come up with the circuit.
Hope there is a smart guy that can help Cheers Jacko

Re: Help with wiring two way light

Its quite easy, but I don't know how to draw here...umm Ill try to do it in words.

You need 2xSPDT switches, ie, 3 terminals without center stop.
Lets give the wires colors.
From the battery, for example, red + and black -
Take the black to one of the terminals of the light.
Take the red to center of the "outside" switch
Take another red to from top terminal of outside switch to top terminal of inside switch.
Take another red to from the bottom terminal of the outside switch to the bottom of the inside switch.
Take another red from the center of the inside switch to the other terminal of the light.

No worries mate...

There ya go.

Re: Help with wiring two way light

You need 2 - 3 way switches. Diagram is for AC. For DC omit green wire, white is (-) and black is (+). Red is additional wire that runs between switches.

Re: Help with wiring two way light

It can also be done with only 2 wires between the 3 way switches, and I'm not talking about using the ground as a neutral. Only old electricians and farmers know how to do it. It was standard practice with knob and tubing wiring. Sometimes know as a "California 3 way". Google it. You're welcome.
