Good quality at a low price

Using these in a high-current power supply to switch current sense resistors. Lowest price found for a comparable product (even those without the socket and wires), fast delivery, and good (at least OEM) quality. The only problem I found was that the wire crimps in the socket were a bit light, but this was remedied by removing and soldering those connections. Contact resistance measured (at the relay prongs) 6 mOhms, and the coil draws 140 mA. @ 12 V. 5 stars overall !
