Oil Pressure sender disected.

Hi Guys,

I just happen to get a hold of a Rotax fuel pump and a Rotax oil pressure sender and
I just couldn't resist the urge to explore. So out comes the saw and presto the guts
are exposed.
If you look close on the oil pressure sender you can see a plunger just under the
center of the main arm and when pressure pushes on it it in turn moves the arm,
which is held down by a spring until the pressure pushes and that moves the rheostat
lever which changes the resistance which is then calibrated for your oil pressure
gauge. Damn this is hard to follow.

If none of this makes any since, it didn't to me either and I typed it.:unsure:
