Apply 5v to all the pair or PINs until you hear a click sound. They are connected to coil.

Are you sure that you are talking about the kind of relay that you have shown in the picture?
I have never seen any kind of relay which looks like that.
Are you talking about a sugar cube relay?

It is also called a sugar cube relay.

Here is the datasheet for your relay , i hope this will clear things up :

The pin connections are given at the bottom right of the 1st page.

If you still dont understand how to use it , then google for "dpdt switch" or "dpdt relay"

A DPDT relay is the same thing as a DPDT switch except that there is a coil instead of the mechanical switch.
