you look bad doesn't it?

The OP didn't ask for a particular package and all the relays referred to are suitable for automotive use. They're thick as shit Steve. If it doesn't plug directly into what they |
help them if they actually had to make or modify something.

Not from Maplin. What the fuck did I say? Such places as, meaning "along the lines of". If you're going to say they can be found there at least do the homework. Most people who know what a DPDT relay is will know of the existence of maplin and RS. Apparently not otherwise they'd have found them at RS. |

Care to give the part number of one you consider suitable? Why? Are you incapable of reading or do you not understand a product |
RS Stock no. 376-880
But as there are SPST solutions up to 70A that'll fit in a standard
automotive 5 terminal relay socket, it seems a bit daft.

Thanks for all the responses. Yes I really do need 30A well ok 25A. It's a common problem with electric windows on 70's Italian cars. You can build a relayed circuit to reduce the length of the ground wire which significantly speeds the motors up. |

you a circuit diagram of the common way.

a minute).
If the relays are in the door (usually luxury cars only, which probably
includes any Italian car that had electric wondows in the '70s), then
adding a decent earth strap across the hinge is often useful.
You don't need to run a ground to the motors though, because the usual
circuit is a reversible motor between two SPDT relays switching each
end of the motor from ground to +12V. Close one relay at a time for up
or down. If there's no good earth at the relays then you could do with
adding one. They'll usually be under the dash though and already have a
good earth. I can't see why running an earth near the motors helps
though.

Yes thanks, sorry for not replying earlier.
Looks good to me, so I'm going to try it out as I have a bunch of SPDT
relays hanging about
