Oil leak from a sensor switch under the oil filter

[Duke92]

Hi can anyone confirm what switch would be leaking oil underneath the oil filter on a austin meastro 1.6 s series is this switch easy to change and will I have to drain the oil?

Oil pressure switch (which I think you already guessed!) , easy enough to change, no need to drain oil, just be careful not to overtighten the new one and don't use thread tape on it..
