If anybody cares: I found out that a simple momentary connection is all that is needed, using the metal tip of an ink pen on the power switch terminal posts on the motherboard. So, a SPST momentary switch is the minimum needed.
Having the motherboard exposed on a table in front of you is much more convenient for testing the motherboard, CPUs, RAM, etc. Try it! Note this applies to ATX type power supplies, where the + and - posts for the power switch are embedded in the motherboard. The old AT power supplies required a bulky external switch.
