I don't believe using the manufacturer's terminology to describe a component is being "overly pedantic" - I believe it's simply being accurate.Let us not be overly pedantic. The switches sense pressure, and open or close accordingly.
There are oil pressure switches and there are oil pressure sensors. Oil pressure switches are binary devices that complete a circuit above a specific pressure and open the circuit below a specific pressure. Oil pressure sensors are analog devices that vary their resistance infinitely based on pressure. Oil pressure switches and sensors are not interchangeable.
At my day job, our products use air pressure switches as safety interlocks to monitor blowers. I cringe when I hear others refer to them as "air flow switches" (they respond to pressure, not flow) or "air cells" (that wildly incorrect description descends from the use of "sail switches" that respond to flow, not pressure).
