    Your post is vague, but I'll take a stab at it.

    The switch is probably for a dummy light on the dashboard...Oil pressure above minimum=no light, low oil pressure=light comes on.

    The sensor is probably for a gauge set-up.

    Your oil pressure gage is not a gage at all. It's a glorified idiot light. All it does is tell you if you have pressure, not how much.

    Check with the gang at they'll be able to answer any questions.

    Baja is absolutely correct,a sender unit drives a gauge via a variable resistor,a switch turns on a light.
