I've never been under the hood of one of those, I'm sure many others here have though. You'll get a reply.

They in fact are Hobbs Switches.

I believe on that car, one is high pressure light and the other low pressure light (indicator)

That's what I thought. Now how do I know if these work. I had popped them off earlier and one had dust and rust inside the other one was in better shape.
