The Oil Pressure switch if broken off will drain "pump" the oil out of the engine very quickly.
an oil light is designed to come on when there is NO oil pressure or LITTLE oil pressure. that said, when your oil light is on before you start your engine there is NO oil pressure to turn it off until you start the engine.
Some are designed to shut fuel pump off if oil pressure drops. Engine seized?
If you problem is that the gauge shows oil pressure with the engine off, you have a gauge or sending unit failure.
If the oil light is working and is off with engine running, then you have oil pressure. To determine how much pressure, you need a pressure Gage.
If you are asking if the engine will shut off when the sensor does not detect oil pressure, the answer is no. It will run without an oil pressure reading.

Most cars would not have any oil pressure until after the engine starts turning because the oil pump is driven mechanically off of the engine.
No , just an engine oil pressure warning light that comes on if the oil pressure is too low
What size engine?
