Oil pressure switch thread size

[maviczap]

Anybody know what size the thread is of the oil pressure switch

I want to fit an oil pressure gauge and the standard sender size is 1/8 Npt thread

The switch is a right pig to get to on the block isn't it, just to the left of the oli filter but only reachable with tiny fingers
