Gold C8020 (19106700) Engine Oil Pressure Switch with Light

Q: Is this a normally open switch? Closes when it senses oil pressure?

Opposite. It is normally closed and grounded, that's why the light is on when key on, engine off. Pressure of oil opens the circuit.

Q: c8020 oil presure switch, will this fit a 1968 firebird with a 454 big block chevy and what is the oil presure range.
