Yeah, but that's Radio Shack, so take it with a grain of salt... Looking at a Bosch relay I have here on my desk (OK, it's a Potter&Brumfeld, but it's just as good...) terminals 85 and 86 operation the coil. Terminal 30 is the "fixed" end of the switch, and this one has 87 and 87A, so it's a "toggle" relay or SPDT. I also have relays where there are two 87 terminals, which are DPST (I use them for lights.)
Eagle is correct in that the power for the load should go to the "fixed" terminal, or #30. This is technically correct, given the function of the relay. Is it mandatory for everything to work? Not really, but it's always a good idea to follow standards - it saves headaches when troubleshooting...
