These are 12VDC 40 amp 4 pin relays. They have several common automotive uses like cooling fans, fuel pump, lights,winch controls and many more. This sale is for a pack of 6 relays new. They might have been pushed into a socket so the pins will show this. They have never been used and are new product.They are SPST type. I have several sets in stock and If you need more, we offer 25 and 50 packs as well. E-mail with any questions. I buy bulk and only use brands we have used in the past without problems. The brand shown in the picture is one of a few we stock and we ship what is in the inventory at the time of the order. The brands are all the same spec and style and are left over product from when the application required the model without a mounting tab. Check my other auctions for relay sockets bulk with crimp on terminals.
