Mouser has bunch of 10A contact rated relays with 12VDC coils. Mouser is always my first choice for components, and eBay my last choice only for when I'm desperate and can't find something anywhere else. I always select standard USPS shipping, and parts almost always make to me in NJ within three or four days, max.
Here, I'll make it easy for you:
