I am looking for a relay diagram that will allow me to use a (-) auxillary channel output from an alarm system to trigger a relay to turn on or off a 12volt source. ie. neon lights /radio/ ect. The end result, first push of the button on the remote will turn on device. The next push of the button will turn it off. Thanks in advance for any input!

Hi install_tech, all you need is a latching relay to control it as you described. You can get them at most Radio Shacks or your local electronics shop.

What's up install_tech, I have a diagram but I don't know how to get it to show up on here so I'll type out the connections. This one that I will explain is for hooking up your radio to the auxillary.

PIN 85 = aux. output from alarm

PIN 86 & 87 = to radio's memory wire

PIN 30 = to radio's ignition wire

PIN 87a = to radio's ignition wire

NOTE:the ignition wire to the radio is cut between the connection of 87a and 30, the wire is not solid. Any other questions post em'

I would like to make a circuit that uses a pushbutton to act as a spdt switch. I want to make it where its normaly off, i push the button once and it flips to one way, i push it again and it flips the other way, and i push it again and it turns off. I have about 20 spdt 12 volt relays so the circuit can be as big as it needs to be. Any help would be great!

do you only want to use spdt relays? or do you care to use a module that will do that? what are you trying to accomplish with this setup?
