My thinking was wrong. The pressure switch, when installed, never sees atmospheric pressure unless there is a leak in the system. It should always be at around 90 psi depending on the refrigerant. 2 terminals is sufficient.

I used water, which showed where the leak was coming from. It was coming out about 1/2 to 1/3 as fast as I could blow into it, which tells me I may have a leak somewhere. The compressor front main seal is notorious for wearing out too.
