What does this switch Do?

Is this an Oil switch for a light or for a gauge in the dash..

Mine is leaking and i assume it has to be for a guage but parts stores are trying to sell me a switch with a large steel canister on it........

Looks about like the oil pressure sending unit. It would be locatd just above your oil filter.

If the bigger one they're trying to sell you looks like a big brass bell, it's for a fox.

Although technically it is an oil pressure switch (not a sending unit). The SN95 Oil Pressure gauge in the dash is basically a dummy light with a needle attached. There is an inline resistor so that when that switch sees enough pressure (IIRC only 5-10psi) to pass voltage, the needle moves to the middle of the range.

The ones with the brass bell are actual oil pressure sending units.

Ok now were getting somewhere.. So they gave me a $10 switch that looks slightly different to the factory one above, but it is just a switch for a light not a pressure guage.

So will this slightly different looking one do the job or does it have to be 94-95 specific like the pic above

I'll respectfully disagree with the sending unit calibration debate. The gauge is what has the hysteresis built into it. A resistor would just lower the gauge reading (as was done on a particular motorcycle because owners freaked when the gauge read high. The resistor was part of a TSB to 'fix' the issue. And you thought the cooling fan circuit breaker was a poor fix ).

To reiterate, the part you showed is for your gauge, not a switch for an oil pressure light (which we don't have, last time I checked. We have a low oil level light, which is a *sensor*).
