Oil switch/choke help. - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm looking to add an oil pressure switch in conjunction with the electric choke like the factory.
I see there are 1,2 & 3 terminal switches available.
I can't get a clear answer on which one I need because they don't list how they operate. I'm thinking the one wire closes the contacts with pressure and thus could be used on the ground side of the choke coil.
Or...use the 2 terminal version and use it on the hot side of the coil.
Anybody know the easiest way to do this? VetteVet?
