An Oil Pressure Switch is an electrical switch that senses changes in the resistance of metal due to heat caused by friction, thus switching the Oil Pressure Switch on or off depending on changes in temperature. Oil pressure can be created using pumps, turbines, compressors, and other fluid power devices. Oil switches are also often referred to as Oil Pressure Sensors. Further discussed in this article below:
Oil Pressure Switch
An Oil Pressure Switch is a device that uses the pressure of the oil itself to make or break an electrical circuit. It can be used as a sensor for indicating low oil pressure, or it can be used as an electronic switch for controlling equipment based on operating conditions within the engine. They are typically found in automobiles. Oil becomes pressurized when it heats up under normal working conditions by being trapped between moving parts inside the engine block.
These switches have two terminals that carry current at all times. Still, they take no voltage until there is a drop in oil pressure. It causes a change in resistance due to heat generated by friction, which causes the conversion of kinetic energy into thermal energy and makes the trapped oil hotter. Depending on the application used, they are typically designed to operate between 30 and 100 psi or so of oil pressure. They usually have a built-in check valve that prevents hot engine oil from flowing back into the pump when there is no system pressure.
It can be described as an electric switch that operates using fluid or mechanical change in devices like pumps, compressors, turbines, etc. These switches are primarily used to sense abnormal working conditions like low oil pressure.
Importance of Oil Pressure Switch
An oil pressure switch is an essential part of your engine, as it helps prevent the motor from being damaged by too much stress. It works along with other components to help ensure that the car's engine is always working at peak performance. When you are driving on the highway or racing down a straightaway, your vehicle is being pushed further than it might typically go. This causes extra strain on the engine, increasing the oil pressure. If this happens for long periods, your engine will be put under extreme stress and could fail.
Unfortunately, Oil Pressure Switches don't last forever; they can either stop working properly or become stuck in one position. When this happens, you may find that your Oil Pressure light has come on or that you don't have any Oil Pressure. They are replaced to ensure the safety of your engine, but this shouldn't be done without first testing it. Testing Oil Pressure Switches is very easy and can either be done with an Oil Pressure tester or resistor; no special tools are required.
Checking oil temperature and pressure
When the oil temperature runs too high, or the oil warning light stays on, the Oil Temperature Sensor is faulty (not reading the right temperature). First, check if a metal clip is attached to the sensor (spring clamp) because the oil pressure switch usually comes attached to the sensor wire harness with a metal clip. Remove the old oil pressure switch from another end of the wire harness (if Oil Pressure Warning Light is on, Oil Pressure Sensor has failed ).
The oil Temperature Sensor should be connected to the oil filter housing, so unscrew the Oil Filter housing and screw the oil temperature Sensor back (to Oil Filter Housing) with a new Oil Pressure Switch (with a metal clip attached to a wire harness). It usually has two wires. Connect one end of the Oil Pressure Swcvb itch wire (with resistor inside) to battery negative (-), connect the other ends of the wire to the starter solenoid terminal (not to Starter Relay - it's a different thing); make sure you use ring lug or eyelet connector. Turn the ignition key in the On position, but do not start the engine; wait for the oil pressure gauge needle to move up.
Now check if your Engine Oil Pressure light stays on (Oil Pressure Sensor has failed; Oil Pressure Switch is still good).
Applications of Oil Pressure Switches
Oil pressure switches are built into most cars and trucks manufactured today to protect the vehicle's engine. Oil switch failures account for many car fires on cold mornings when automobiles with complex engines idle too long before starting their drive systems (heater, defroster, etc.).
When an engine is left running for a short period to warm up, the oil pressure will rise, causing increased activity at the switch and providing increased current flow through it; increasing the heating of the Oil Pressure Switch, which will result in increased resistance to current flow.
They are also commonly used as safety devices for turning on lamps or other electrical equipment at a pre-set oil pressure level, typically around 50 psi. Oil switches are also used to activate valves for controlling fluid power equipment. They can be normally open or closed contacts depending on the application.
