Default Oil Pressure Switch

Hi, I need help locating the oil pressure switch. I cant find it anywhere, I have looked on the passanger side by the firewall near the oil filter and I still dont no what it looks like. Is it easier to access the switch under the car. My oil pressure is very low at idle. it goes into the red zone after the car warms up but will move when the rpms go up. Is the dangerous for my car?

Oil pressure droping off into the red is not a good thing...

The oil pressure switch is on the passenger side of the engine, look above the oil filter adapter on the firewall side of the motor, not too far from the power steering pump, the oil pressure sending unit will be about 2.5 inches long...

It looks like this:

The back part with the wire coming out of it in the middl there

And I was able to access it easiest through here:

The splash shield on the front there is removed.

This is on a 93 SSEi, but should be the same for others.
