Contactors--which way is up?

[72878]

I am seeing some mixed signals on which way the main and starter contactors should be mounted, with some of the datasheets silent. I am planning to reuse the old ones and buy a little more avgas.

I am pretty sure what I want is + Gs to close the main and open the starter contactor which to me says the little hat on the main is up and on the starter is down.

Am I right? Whats the consensus on this.
