a different kind of relay for ignition help

[JDP12]

Hey, well i got the parts for my ignition, but i have a different kind of relay. Here is a picture of what it shows for the pins, so how would I wire this type?

those squares are pins, yes there are eight

this a link to the relay: http://www.radioshack.com/product/index ... age=search


I'll be using this with a camera capacitor and ignition coil by the way

EDIT: It is a double Pole double throw relay, here is what wikipedia says about it

DPDT - Double Pole Double Throw. These have two rows of change-over terminals. Equivalent to two SPDT switches or relays actuated by a single coil. Such a relay has eight terminals, including the coil.

what do you want to do?? the thing acts as two switches which are separate. when the relay is off the switches are connected to the one contact. when the relay is on they switch to the other contact. you can use it as two separate on off switches!

[JDP12]

I need to figure out how to wire it like the one in the spudwiki how to, or at least how to make it perform the same task.

[TechnoMancer]

firstly these are usually not very big so what is it switching. i'll go look at the article now.

[JDP12]

k its under camera flash ignition

[TechnoMancer]

what are you building so i can tell which article in the wiki to look at?

[TechnoMancer]

can you send a picture of the top of this relay or of the side with the diagram on it?

[JDP12]

umm here, sorry that doesnt have a picture of it, i'll keep trying

OK I've seen the link. but it is rather hard to explain. on your diagram you want to use pin 9 or pin 12 for the one connection and then probably pin 5 or pin 8 for the other.

soo run the battery to pins 9 and 5, then run the ignition coil to pins 12 and 8? here's a pic of what i mean

no
the battery and switch must go to 13 and 14 cause those are the switching coil!!
the capacitor and coil can be wired like that though

[JDP12]

ok sorry, I just have no idea about these things.

So it would look like this?

Thanks for the help

that should be right.
if that doesnt work the coil could be connected to pin 4

[JDP12]

okay thanks for all the help i really appreciate it

Yep, that looks to be about right. Those relays basically just let you operate two different circuits at once, but you can just ignore one switch if you want to.
