Yet I believe this one is closer (however mine is all plastic): http://www.ebay.com/itm/Engine-Oil-L...96a594&vxp=mtr

I wonder if we're talking about the same switch. What you're looking at in these two links is a low oil level sensor located on the pan of your engine. That's not the switch I wrote about in a post above. The switch I'm talking about is located at the bottom of the oil filter housing. It's near the dip stick tube which is what you mentioned in your post. Here's a picture of an oil filter housing removed that shows the low oil pressure switch for the light on the dash. If we're talking about the same item, its GM part number is 25036935 or AC Delco D1846. It's an easy part to buy.
Note that it has only a single wire attached to it.
