7i96S Basic Switch Wiring confirmation

Hi all, I know this has been aske before, however, there does not appear to be a simple visual on it. So thought I would confirm.

I am trying to set up limit switches. I would like to first test config on single switch. I believe that the best way is to wire a 24V power Supply +ve to the switch, then switch to the boards input Common. Then Wire 24V -ve to Input #. (Ref: Image attached.) Is this correct or should it be switch interrupting -ve side pathway?

I believe that once tested as confirmed I can run a single series based set of switches to use for X, Y and Z limit switches. Correct?

Thanks all.
