I am going to change the oil pressure sensor and switch in my gs spider. I was just wondering if all the oil would drain out of the oil pressure switch at the bottom when I remove it to put in a new one, as I have just had the oil changed and don't wanna have to buy 4 more quarts lol!

Not all, no. If you had just run the engine, there'll still be a fair bit in the oil galleys. But the majority of it is in the pan. The sensor is part way up the engine block on the firewall side.

If the car has been sitting for an hour, you might get a few drops.
