Hi All,
I have a 12v switch panel which is currently connected to my main car battery with a 60 amp circuit breaker (Hub style switch). However i want to have a switch which is separate so the switch panel is able to receive power from my second battery but not receive any power at all from my main battery. It would then be hooked up to a 10 amp circuit breaker from the aux battery as i wouldn't be running as much while the car is off. Obviously the main battery running to the switch panel would be on a 60 amp relay this diagram is just for simplicity.
Diagram of what i think it should be below:

 

IT IS NOT CLEAR WHY YOU NEED A 60 AMP RELAY.
A simple switch to disconnect the second battery from the first is what you would use.

 

First, You need to state what problem You are trying to solve,
an/or, what problem that You anticipate possibly having in the future.

What is the purpose of the second Battery ?
Is the second Battery similar in capacity to the Main-Battery ?

The switch you show in your diagram is common SPDT switch with the out connected to the common terminal. What is the problem?

 

IT certainly IS IMPORTANT that we understand the problem to be solved, or at least the results to be provided, to avoid a string of random guesses. Adding a second battery is fairly common in some vehicles, but for various purposes.
