Why in the world would you want to do this? If the sending unit is defective then replace it. If the light is on you either have low oil pressure of the sending unit is bad. Low oil pressure will ruin your engine.
You are referring to two separate things. The fuel pump has a relay and not a switch. The oil filter does not have a switch but the oil pressure has a sending unit that sends a pressure reading to the gauge. Some cars have an oil pressure switch that incorporates a circuit to shut the engine down in case it were to loose oil pressure.
if your pressure switch acts up at all, replace it.
