Hi all,

I'm looking for four Dual Pole/Dual Throw (DPDT) 12V 30A(ish) relays for
an automotive applications.

Most suppliers seem to just do SPDT types.

Anyone know where to get them from and/or if they are fitted to any cars
I can get them off

thanks

Lee

if you are in the uk try maplins.co.uk

I doubt very much that you'll find what you're looking for. I find
automotive relays rarely come in DPCO format, especially not at
25-30A. The closest i can find is an industrial relay rated at 25A
DPCO.

They are available from RS (www.rswww.com) and no doubt many other
suppliers. However, looking at the prices i think it would be cheaper
to buy two SPCO standard automotive relays.

Product: go to www.rswww.com and enter 376-880 in the search box.

I can't think of anything that would use them on a car?

Just how much current do you want to switch?

What's the actual application so perhaps someone can suggest a different
route?

Pretty common at lower current ratings, but 30A is pushing it. Do you
really _need_ 30A ? If it's for lighting, then split it into separate
circuits across multiple relays.

A 30A one can be found at such places as Maplins or RS Components.

Why do you need double throw? There are some Lucas DPST ones around
(they may have one contact of each pair linked to one terminal) in
oblong aluminium cans. They are usualy available from traders at shows
and classic electrical dealers. If you need DPDT for logic just use
lower rated relays feeding a couple of standard SPST automotive relays
for the high current circuits.

I used to use ex-WD relays from the shops around Edgware Road and
Lisle Street but that seems to have all gone now. Henry's is still
there but I haven't been in for a long time.

They're DIN rail-mounted, not the usual car format, and Maplin don't do
a 30A DPDT anyway.

30 amp DPDT with a 12 volt coil? Not from Maplin.
