Switch ID request.

Evening All,

In this pic, the switch on the right is the M151 oil pressure safety switch.

The switch on the left has no vent line aperture and is bigger.

Can anyone tell me which vehicle it belongs to please?
TIA

Guessing there are no part numbers at all?

Looking at the picture, it looks like one sensor has a single electrical connector (maybe self grounding?) and the other might appears to have two electrical connections? Possibly?

No part numbers.

The 151 switch has the standard 3-pin Packard, but the switch in question has a single Packard.

I have never seen one without a part number.

I have never seen one without a part number.

I found this stamped on the side.

Suggests a 151 oil pressure sender, but it's much bigger than I remember.

 

[Guyfang]

Found what?

MS-24538 TRANSMITTER PRESSURE 24V 60 PSI

Thank you very much.

Any idea which vehicles it would be fitted to please?

60PSI senders were stock on M37, M38, M38A1, M35, M54, and a few others. It all depended on the target oil pressure range of the engine.

The same one would be on an M151, the other unit with multiple connections is the pressure switch that turns off the electric fuel pump if the engine stops.
