I want to have a 3 way switch at mid bus and at rear of the bus to activate a relay. I have two wires run to the back, one from the breaker(Red) and one to the relay(Yellow). I have a 3 wire( B W G) run from the back of the bus to the middle of the bus. In the middle I put the B wire on the dark post and the W and G wires on the gold posts (Travelers). At the rear of the bus I connected the black wire from the middle of the bus to the Yellow wire, the W & G to the gold posts of the rear switch and the red wire from the Breaker to the Dark post of the rear switch. The switch will turn on from the middle, and off from the back but will not turn on again from the middle. I have tried every possible thing and still not good. Any Ideas?? | ||

If you want it to work like a three way switch in a house you will need two Single Pole Double Throw switches without a center off position. Starting at the breaker we take a single wire to the common connection of the first switch near the center of the bus. From there we need two wires going from the other two terminals of the first switch to the same terminals on the second switch. The second switch then has a single wire going from the common terminal to the coil of the relay. The other side of the relay coil goes to ground. And that is how a three way switch works.  | ||

What voltage do you want to switch and how much current? There is another way! For about 10 bucks if it's 12 volts. | ||

Or he could just get a "Clapper". "Clap it's on; Clap-Clap, it's off." All the old farts have' 'em. I think the AARP gives 'em out. | ||

 12 volts, Has 6 amp relays and only needs a single button or ten or however many you want. 1-wire to ground to activate. I use them for lights, small motors and all sorts of stuff. I have lighted buttons also. | ||

from what you describe it appears to be wired corrctly are these household switches | ||

Here a link to what David suggested; http://www.intellitec.com/pdfs/MOTOR%20CTRLS_web/5300193.000.pdf It a remote relay to run 12v 20amps motor. How much it cost or what can we get them for $$? David! Unless price is right, there is lower cost version use single SPDT w/center-off or twin push button momentary switch for each station or room to control same lamp or whatever unit. Lord willing, I will try to come up a low cost circuit on board later unless someone already post one. X10 is similar one but use 110v AC. w/digital signal control. http://www.x10.com/x10_ahptt2.html?cf458c19078b6f344285fa94 FWIW Sojourn for Christ, Jerry | ||

Mine is cheaper but you might need an external relay for 20 amps or more. I bought barrels of these surplus and have been hauling them around for 4 years now. I have been holding on to them in hopes that eventually someone would/could use them. (other than me.) The neat feature is the lighted LED & Function only needs a single wire to the module, The other end from the switch is to 12 volt ground. Diagrams that you can actually see are on my website under the "Stuff" button. The price is under "electronics" button." www.rvbus.net " This is the only time I will post this information here because I don't want to upset I@N any more than necessary.  | ||
