This fuel pump oil pressure switch completes the circuit when it "feels" the oil pressure (4psi and higher). I used it to supply power to the electric chokes on a dual-carb set-up. It is rated for 12v but it works fine with 6v.

It looks like the part has changed - it shows 3 contacts but I think that mine has 2 contacts.

Here is a 2 contact switch.
