It is important to have the right amount of oil and oil pressure in order for the engine to run smoothly.
About Oil Pressure Switches
Most (if not all) cars have a gauge that is connected to the oil pressure switch.
In case of a problem (ie low oil pressure), it cuts out flow of power in the circuit and turns on a warning light. One must immediately stop and turn off the engine.
