Specifications for automotive relays and switches?

Why is this stuff a secret???
Where can I find data sheets or specifications for automotive parts such as relays and switches? (Amperage ratings of contacts, pin and internal
component diagrams, duty rating of relays - continuous duty, etc.)
All the usual things provided by everybody else in the electrical world!
But this information is not anywhere on the internet and the only thing on the product packaging is a part number! No ratings are on the devices either! Just a part number...
Or is there an automotive parts manufacturer who provides this basic information on their web site?

Good luck. These are not intended to be industry standard parts. They are proprietary parts for specific applications. You are not going to find these kind of specs for proprietary parts from IBM or Apple either. The best hope will be when cars become a global commodity, assembled from standard parts like the "clone" PCs. It is already going that way.

** Cos folk like you simply do not need to now.

** Probably no-where.
Car makers put out tenders for such parts and suppliers produce devices that do the job for the lowest possible cost.

** Car parts and spares for cars are a whole world unto themselves.

** See above.

** What for?

** Relays supplied to car makers need only work at 12 volts DC.
No other voltages or AC ratings exist for them.
Bloody obvious, really.

Relays are easy - the common ones tend to be 30 amp.
Here's the pinouts:-

As regards switches there are so many in use it would be difficult to give ratings for each and every one - especially since so many no longer switch things directly, but just operate an electronic switch.
But if you know what the original app was and it was switching direct would be easy to make an educated guess.
The same firm does a range of modular rockers and they're 15 amp.

Putting my conspiracy hat on. In Europe , defense /medical /aero-space manufacturers , have a derogation allowing the continued use of leaded solder/components, but AFAIK not automotive industry. They all know that to allow lead-free with heat and vibration of a car then they will hardly get out of the factory before solder joints start to fail - so they keep quiet about continuing to use leaded "tinning" of components and leaded solder?

Ford, GM, Chrysler, Toyota, Honda, Hyundai, Kia, Holden, Nissan, Subaru, VW, MB, or what?
Each is different. Different maker, different specifications.

Bosch has reduced the variety of relays available in the US. There are 24VDC relays typically used in heavy equipment and marine. You can try Hella and Tyco, Hella used to put out a catalog, lots of luck with Tyco, although they do have data sheets if you drill into their web site. There is a US automotive switch manufacturer (can't think of their name) that makes a variety of automotive and heavy equipment switches, some sealed.

I used to own an old Ford Escort, The Bosch plugs (2 sets) also cracked around the centre electrode and dropped bits of ceramic into the engine. I though it was just me.

But all (us) Saab Turbo owners know that you should only use NGKs!

You might try SAE AS5363 perhaps with SAE J2544 or SAE J1859 or SAE J1744 or SAE J2907. Typically before you have enough to really work with you will find you have to buy about a dozen or more standards. Start with 1 or 2 and find the rest from the referenced standards that those are written against.
