I'm confused...a
switch, by design, will have at least two terminals.
I think the late cars did have two wires going to the light(power and ground), where the earlier cars only had a power wire to the switch. The aforementioned mercury switch would then provide the ground side of the circuit when the hood was raised. It really depends on how you want to do it. All you need is a simple on/off switch, cut the power wire going to the light, and splice in the switch.
I'd say if you are purchasing the switch, go for the "dual terminal", and it should plug right in.
