AC Compressor button switch

[Hook'em]

In the process of replacing my heater core this past weekend, I managed to break the ac compressor button switch (I found the wires dangling still attached to the terminals). I have a new part, but I don't which side to affix the green wire and which side to affix the yellow wire. Since the button switch seems to merely open and close a circuit, I don't know if it even matters. I used the search function to find many threads on the ac, but not one specific enough to answer this question. Any advise is appreciated.
