For dc contactors (relays) there is one big manufacturer: ALBRIGHT.
These parts have many advantages I think - many AGV suppliers use them on their vehicles.
But don't look for datasheets or something like that on the internet - there is nothing or better said nothing usefull.
You can get these Albrights with auxilary contacts 1NC+1NO. This seems to make them suitable for safety circuit where you need a feedback from the relay if it it opened or closed. For safety applications the actuation of the aux-contact must be direct without a spring in between. But this is the case with the Albright. They put a spring in there.
So PLEASE don't use it for safety-applications - it is not safe.
