I'm not sure I understand what you want nor that you understand how relay's are wired. Have a read of https://en.wikipedia.org/wiki/Relay
Your average relay has four or five terminals. Two to switch it (the inputs), one common output, one NC output and one NO output.* Four pin relays will only have two NO output pins.
The inputs and outputs are isolated from each other.
What determines the power being switched is what the device on the output side of the relay needs.
If you want to use a bunch of relays to switch a bunch of 12v devices you can wire all of the common output terminals to the 12v and either of the NC or NO outputs to the device then to ground. Assuming your 12v supply and wiring can carry/provide enough current that is.
*: NC = Normally Closed, NO = Normally Open. Think on or off.
